Motorcycle was running super lean. I calculated what size of jets and shims I needed. I came onto order and found their jet calculator!! Used their calculator and it recommended the 120 jets. I had 122 calculated. Got the jet and shims and bike is running much better now!Thank You so much! Gave them a 4 star for shipping because I wish I could have had the jets and shims shipped Priority. Even with this shipping, it only took 4 days from Florida to Arizona.
your Jet kit really made my bike come alive it really runs strong and good im very happy Thank you i have told all my friends
I received the Honda VF1100S saber 1984-85 Ultimate Jet kit - Hvf1100s84 and installed it the day I received it The V4 is a real pain to remove and in stall the carbs ..

My 1984 V65 Saber has a K&N filter in stock air box with Cobra F1 slip-on Mufflers, stock ignition..

I had a flat spot in the rpm range at 5500-6500rpm,a lean condition. With the ultimate kit and adjusting the float levels to the required 7.5mm(9/32) One float level was not in the required range,with two shims per needle transformed the performance machine pulling strong to 9800 rpm.

The jetting was spot on! The pilot screws where adjusted and final location was 2 turns out from being seated.

After a strong road test I checked the sparkplugs and they showed the correct fuel mixture (very light gray ,no soot).

Engine idles smoothly no over rich conditions. Very nice preforming setup.

I'm the original owner of this bike from NEW in 1984.

Yes I'm an old Dude,70 yrs old still turning wrenches on motorcycles and cars.


Thanks for a great kit,
After trying several modifications to the exhaust and intake, You folks have been a blessing to work with. The bike runs like a champ. Thank you.
Kit corrected the lean condition after adding free flowing exhaust THANKS
These guys know what's going on installed my kit on 1983 interceptor 750 and it runs so much better it's like night & day!
I had a little tuning problem contacted carbjets & john responded
immediatly to me and his info was spot on.
Thank you rick
Ordered the Ultimate CarbJetKit for my '07 Honda Sabre. Installed and worked great. I have a few questions, called CarbJetKit guy and he took care of us.
kit arrived quickly, and although I had never broken down this bike the online instructions were great. Started on first tap when back together, and recommendations for correct kit were righton.
I built a Honda Bobber from my VLX 600 and had an issue after adding my after market parts but with the help of these guys Jet Kit Calculator my bike now runs like a champ!
I put pods on my 1982 honda nighthawk 750. Wouldn't hardly run. Placed your kit. Fantastic improvement. Thank you
I have a 98 Valkyrie , put a set of cobra 6 into 6, removed the baffles, and put a k&n air filter, call theses guys told them what I had done and the sent me the kit, my mechanic looked at it and scratched his head... 2 sizes up on the small jets, 2 extra washers on the needles, and 7 sizes up on the mains, went from 100 stock to 115's on the main jets, he questioned me was I sure this was right???? I told him I had called and talked to them in person, and they said this was what I needed, put them in, about 4 hours later we fired it up, sat and idled smoother than before I did any changes, we looked at each other and just smiled, now the real test, down the road about 6 miles letting it warm up, turned around and WOW!!!!' hang on !!! I don't know how it could have been any better, no hesitation, no stumbling, just steady PULL!!! We put 260 miles on yesterday, run fine under (normal driving conditions) my mechanism said he would never have believed that it ran ok on the stock jets, and we could go from 100's to 115's and it not be too rich, but I think they were on the money, don't question what they send you, just put them in and smile when you twist that throttle!!!!!!
Very simple and succinct. Installation straightforward. Results were what I expected. Bike runs great. Loved the jet kit calculator----spot on.
Flawless from the jet calc to install, these folks are providing a heck of a service to bikers. Support them by making your bike run awesome.
Great is all I have to say from the calculator shipping price and the best part how to do it. I was going to pay someone 100 $ to jet my honda cmx250 but I did it in 30 minutes with ease. Highly recommended to all.
This kit was very easy to intall. The parts fit perfectly and the bike works better than when it was new. Recommend these kits to everyone.
The Ultimate kit for my 1985 Honda VT500c worked perfectly. My exhaust mod is cutting the 2 into 1 section of the stock muffler off, removing the guts, then a simple welded patch creating a small chamber that connects to the right side pipe only. Still using stock airbox and filter. I now experience 'accidental' wheelies. It's like a whole new bike.
