Robert Schultz - (Tucson, AZ):
First I'd like to thank you for answering my questions so quickly and
courteously via email. Returning the exhaust I'd already bought to order
yours was a fairly major leap, but one I'm glad I made! I installed the Vortex
slip-on on my B12 last Friday, and noticed immediate improvements. Not only
does it no longer sound so anemic (though quite mellow when not "on the
throttle"), but my erratic idle has smoothed out dramatically ( a result of
being strangled?). Seat-of-the-pants impressions confirm your claims of a 10%
power gain. Installation was completely undramatic and took me about 40
minutes. You should have seen my wraparound grin after the first
round-the-block test spin! The front end has never been so light before!
Yours in Velocity,

Here's an update regarding my stage one installation. Thanks again for your
personal help/advise while I was "dialing it in". The combination
of Vortex slip-on, K&N filter, stage one jet kit, and ignition advancer has
produced a B12 that can run with CBR900RR's easily (until the suspension
reaches its limits anyway - that's next). Everything went into the carbs
without a hitch, and the advancer went on in less than 20 minutes, using all
of four tools. Your printed instructions are excellent - I didn't really
need the manual (but of course would've if it wasn't handy). It now averages
around 32 mpg, only down two from stock, but hopefully a good carb synch will
improve that. It warms up much faster than stock, and is smoother than stock
once it is, even if it now wants a little choke at first (even on hundred
degree days). I love the business-like sound, and the look on the face of
the repli-racer crowd when they hear it coming from a Bandit with hardbags!
There's more acceleration than I know what to do with - more than a sixth-turn
of the throttle in a low gear = wheelie, and even mildly charging off a light
and shifting shy of 5k rpm leaves traffic a ? mile behind when I check my
mirrors! Anyone who owns, or is considering a bike you make parts for, has
gotten an earful from me on where to go, and you'll be hearing from me
whenever I get enough $$ to apply to the other bazillion thing I want from
Holeshot. You Rock! Sorry this is such a long post, but it's one of those
"can't say enough good things" situations.

The new Corbin seat I ordered from you arrived yesterday and looked great.
I'm installing it this morning (even though it's only about 40 out and rain
on the way). The mirrors and shirt arrived previously. I don't know why anyone
would want to use the stock mirrors when they could be using Napoleon's.
Everything was better than expected. When I get ready to sync the carbs I may
be ordering those dials you advertise on the net.
Good luck with the project bike!
I am having a problem with my '99 B6, it is the coldest engine I have ever

My wife's '96 B6 ran worse than yours if you can believe it! When on the choke

15 minutes of "riding", some choke was required. It stalled at traffic signals

The good news is - I fixed it this past weekend! 4 words for you: Holeshot
Stage 1 Kit. Shim the needles with 2 washers, use 100 main jets for all
cylinders and 2 1/2 turns out on the mixture screws. Add new K&N filter
and you are good to go. My wife can't believe how well it runs. Starts, runs
and idles like a champ. I haven't even put on the timing advancer or Vortex
pipe yet (can't get her off the bike long enough!). I thought I would be able
to use the pipe on my B12, but not so. She told me to get my own.
Seriously, spend the $110. It's the best money I've ever spent on a bike.

I stalled my new SuperBike bars with Bar Snake this weekend. The Bar Snake
install was very easy, except it was tricky to get it installed and leave a
1.5" gap for the bar ends to be reinstalled. The weather didn't cooperate
much this weekend to allow me to take much of a test ride, but I could feel an
immediate difference during the short run I did make. I could feel an instant
reduction in vibration and more confident control with the new bar config. My
brother is very interested in a Bar Snake for his '81 CB750F-SS with the same
bars. He could really use it...
Well, thanks for the help Dale. The Snake was well worth it.
Matt Fujimoto - ('97 Bandit):
I really don't have words for the way my sale was handled, WOW, I guess is a
great start. Thanks Dale for the personal touch, I can hardly wait to get my
parts and upgrade my '97 Bandit. I have owned it for three years and have been
waiting for this chance to upgrade. I have followed up on all your articles
in Cycle World and other mags. I love the website; keep it up, guys.

I talked to you briefly on the phone about my recent installation of a
Yoshimura RS3 Oval Canister with a K&N Let Kit on my Bandit 1200, 2000
model. I have installed several jet kits and pipes throughout the years
including factory brand jet kits and Dynojet jet kits. On this particular
installation after doing the 2" mod on the airbox I just could not get the
K&N Jet Kit to perform. I found your website and ordered you stage one
jet kit designed for the 2" mod. I installed the jet kit according to
instructions and set the needle at #2 from the top with all the stock spacers.
Then I tried in half notch settings utilizing the shim to accomplish this
towards the rich side of the needle all the way up to 31/2 from the top. I
went out and ran the bike for 20 to 30 minutes at each setting and the bike
performed the best at #2 from the top with all the stock spacers. I would like
to thank you for a great product with a lot of R&D time put into it.
Note: I had no flat spot off of idle.

It has taken a while, but I've mated your Vortex slip-on to my GSX750X
"Inazuma", and it fits. Another model that you can add to the list
- even if it's not (yet?) imported into the US. Clearance is tight, but I'd
think it was designed to be that way.

The Progressive springs and shock went in without a hitch. It's a significant

Ben Payne - (Santa Rosa, CA):
Just wanted to tell you how much I like the fit and finish of your complete
exhaust system combined with the stage two kit. It went on so easily and fits
like a glove. The weight difference is really noticeable compared to the stock
pipe. It really screams above six grand and the front end comes up in second
gear a lot easier than before. Thanks again Dale, and also for your phone
support at any time I needed it.

This past winter I bought a stage II kit, advancer, header, and Vortex exhaust
system for my B12 from you. Just wanted to let you know that all is now
installed and the bike runs great. No more cold bloodedness in the morning and
no more stumbling at low RPM. The bike just rips from 2K to redline.
Brian Herndon - (Albuquerque, NM):
Wow! What a beautiful silver header that matches the finish of the forks.
This is what I thought when I received this piece of art. And it is so light.
So I took off my old header (all stained and dark brown in color). The
installation was not difficult at all, it is handy to have some good hex
(allen) wrenches though. The Vortex slip-on fits so well into this new header
too. When I started it up I noticed no additional noise from the thin-walled
head pipes. It has a noticeable increase in torque off the bottom that very
quickly gets you to that 6k-9k rush at the top! I wasn't sure if it was all
in my head so I did what I always do...raced my boss with the Hayabusa. We
wanted to take the rider out of the equation so we did roll-ons. In the first
through third I remained ahead of him until the upcoming shifts! Pretty amazing
considering a bike with the Holeshot stage 2 jet kit and full exhaust system
was beating a bike that costs $3,000 more. I can't think of one downside to
this header. Well maybe just one, it is so shiney silver all of the time that
it forces you to keep the rest of your bike clean to match it. Well done.
The rear sets really help with the ground clearance, but are still comfortable

Tommy Hall - (Salt Lake City):
Just wanted to drop a line to tell you how my project Bandit turned out.
I had the full set of mods done including the complete exhaust system with
Vortex header, stage 2 jet, GSXR intake cam, street-strip head port, JE 11-1
pistons, and the ignition advancer. The bike is an absolute rocket now. My
first dyno run was 138.7 HP and that was only to 9000 RPMs. After a number of
heat cycles and more break-in it hit 146.4 HP. I know there is a margin of
error but it sure does not feel like it. A few of my R1 buddies have ridden
it and are absolutely flabbergasted. I can't say enough about Dale and his
shop. He was extremely helpful when ordering parts and would always answer
tech questions when called. The parts were top quality and would always arrive
promptly. I also got the extended swingarm to keep the damn thing on the
ground. What a piece of art this was. I have had more GSXR riders ask me
about it and where they can get one. The work speaks for itself. Once again,
thanks, and I am sure I will be calling in the near futurefor many more parts.
This Bandit is the most addictive bike I have ever ridden.

Thanks for your advise about the bar snake and the long stem mirrors. The bar
snake made a difference. I was really impressed with the Napolean long stem
mirrors. I thought the mirrors were a little pricey, but well worth the money
once you use them.
Dean Cartier - ('00 B6):
I just wanted to thank you for your commitment to your customers. I must have
been one of the first ones to order a Vortex for a '00 B6. Other companies
(you know, the big ones) said we don't have anything yet! They left it at that.
Not you Dale. You said yeah, I think it will bolt right up. That was not the
end of it either. You did over 60 pulls on the dyno, found the best set-up
for the carbs and passed that on to me. Try to get that service out of one of
those other companies. I also appreciate that you did not try to sell me stuff
I didn't need, I only needed to shim my needles and adjust the idle mixture
As far as the Vortex is concerned, the thing fits like a glove. Only cutting
off an ugly wire foot guard was necessary. It also has a great finish. It is
very attractive and I really like the new nameplate. This is a QUALITY product
and it shows. The instructions included were very straight forward and easy to
perform. It is easy to see why you have such a good reputation amongst the
Bandit community! My bike performs great and sounds even better! This has
really added to my riding experience. Thank you for doing business the way
that you do. It really is appreciated. I'll be back for more goodies for sure!

Not wise, but had it at 150mph with a third more twist left on the throttle.

Hey you power hungry Rascals
I finally got home early enough today to play with my jetting again. I pulled
the needles and deleted the washers under the plastic spacer. As you may
recall I started with 127.5 mains on the 3rd notch and the engine has
responded to each needle adjustment with improved midrange response. So now
I'm at the 1st notch (leanest) with only the plastic spacer with 130 mains
and 2 3/4 turns out on the screws. It took me 35 minutes to do the needles,
I only had time for a short test drive of seven miles (upper 70s today) and
there is only a hint of a flat spot with a cold engine as the rpm comes up in
the midrange. Therefore, I still may be a bit rich on the needles.
How does it run? It pulls smoothly off-idle from a standing stop and almost
immediately starts pulling like a bear! With casual throttle openings from a
stop sign, the front end gets light almost immediately and comes up at about
3 grand. Awesome torque. I am very impressed and wanted to pass this along to
Am I dialed in yet? Probably not, but I must be close. This combination has
great merit and I recommend it highly.

I recently completed installing the Vortex Header, Stage I Jet kit for
Modified air box, and 5 degree advancer on my B12. I must say that this pipe
is probably the nicest piece of craftsmanship that I have ever purchased for
a motorcycle. I have owned numerous brands of headers in the past, but never
had anything of the quality, fit, and finish of your Vortex Header. The tuning
of the jet kit and pipe was very easy, as it appears you have done your
homework with the Bandit 1200. I am very pleased with the products that I have
purchased from you and would highly recommend your company to anyone. Thank
you very much for your tuning tips and I really appreciate the fact that you
talk to your customers to make sure that they are satisfied. By the way, my
Bandit runs better and smoother now than it has since the day I bought the
bike. It is really going to be a pleasure to ride now.

The bike before Feb 2000:
Ohlins front and back
5 degree advancer
Ermax undertray - Chuff cover (whatever) bad fitting, but it will have to do
until the Winter, (And it does fit with the Hugger.)
Bandit Mania rear light/indicator module (arrived after a 6 bloody week wait),
even worse fitting, but it will have to do until the Winter.
Vortex Header - very nice

(Dale's recommended starting point - can't find the instructions now), 16mm
float height, 2.5 turns out on screws - And an extra 1" hole (a gamble to
compensate for the Corbin).
At last I took the bike for a test run on Sunday, wearing a T shirt and jog
pants, I thought I would just check some slow riding with some throttle
response checks for a couple of miles, just to check if I had fouled things up.
A grin appeared.................................................
I meant to go home and put on more appropriate clothing and I tried to be
subjective - roll on in third at 4000, check for flat spots etc. etc. - that
didn't last long.
"We don't need no stinkin' subjective."
I was having fun, checking revs went completely out of the window. Throttle
response was AWESOME - the bike just kept pulling.
At an indicated 130, my spectacles started rattling around on my face and I
had to slow down (Must sort out the Ohlins). Spent the next few hours just
trolling around - until I realized I'd lost my smokes, panicked, and headed
Arrived home still in jog pants and T shirt now with bug bits, with sun burnt

Grin still here.................................................

I love my Holeshot Bandit even more
The Vortex Header seems to make the exhaust note a bit more mellow? -
surprise or deafness?
I still love my Holeshot Bandit
One day I will take the Bandit to a Dyno to get things just right (I have my

Thanks to Patman for local advice.
Rick DiBlasi - (B6):
I just wanted to fill you in on my results with your stage 2 B6 kit.
I ended up with 3 shims and the screws at 2.5 turns. I am very impressed with
the increase in performance. Combined with your complete Vortex system, this
bike really halls butt now.
I am not sure these are the optimal settings for my bike, but to be honest,
I am not a good judge since this is my first bike. All I know is that it is
running way above stock and that's all that matters to me.
The warm up is MUCH faster with no choke in warm conditions.
Thanks for the wonderful products and service. I can't wait for my new
suspension components to arrive.
Scott Radtke - (Florida):
I sent you the Mikuni jets and you sent me the modified jets for my B12.
Everything worked excellently. I installed the jet kit along with the K&N
filter and 2" air hole in the airbox. When I reassembled the bike it
fired up immediately thanks to your great instructions. I rode it for days
before I realized it now pulls hard to 11000 RPM instead of 9100 (didn't even
hit the rev limiter). It's truly unreal. What's the max safe RPM for the beast
(stock motor)? Thanks again!!!!
Gary Check - (B-12):
Read your B-12 article in C.W. the other day. All I can say is how mine runs
(1216 cc)......man does it have balls!!! It has 1400 mi. on it now, and it
seems to be getting looser and faster all the time. Have had absolutely no
problems or adjustments to the carbs or anything. Response is immediate.
7-9000 rpms is insane! I am 100% happy with what this monster of mine can do.
Jeff Knight - (San Antonio, TX):
I am writing to thank you for the R&D you put into the parts of your
stage II jet kit for my 99 1200 Bandit. The instructions were very easy to
follow. My brother Jim and I had removed the carburetors, installed the kit
and reassembled the bike in a little over two hours.Now came the fun part,
See how it works. The first thing I noticed when I hit the starter was the
quick easy start. just like you said, my bike was no longer cold blooded.
I had also installed your timing advancer while rejetting the carbs. It was
time to see how these would perform while riding. The results were literally
amazing. My bike used to be sluggish below 3000 rpm, but now it pulled really
strong throughout the entire rpm range. The ease of installation and the
precise jets to achieve maximum performance with no guessing makes the stage
II jet kit a great buy. Thanks again Dale and keep us posted on new products.

Taking a sammich break in from the garage; just got through installing the
cylinder block down over a set of Dale's 1216 pistons.
As with the stock-bore 11:1 set I installed a year-and-a-half ago, the
installation went as smoothly as could be imagined. Bores were honed per the
JE instructions, and all ring gaps were perfect without filing. I did a little
hand-massaging on the domes of the 11:1 set but these needed *nothing*.
Deck height is perfect. Wrist pins slip-fit perfectly... snug, but glide
freely on the thinnest film of oil.
There are numerous piston kits on the market for this old lump of an engine-
take your pick- but after two "complete satisfaction" experiences
with Dale's kits they'd be my first choice if I ever build another one.

First off, I traded in my B12 for a brand new 98 Valkyrie. I had your can on
