Used this kit when I installed some Cobra Drag Pipes on my girlfriends Honda VLX600. Dynojet has done all the homework. I followed their instructions...no problem. Bike starts w/o choke, no idle stumble, and throughout the entire powerband perfectly. Great troubleshooting sheet provided...I didn't need it though.
I installed this kit with a Thunder Mfg air cleaner. Easy install on the VLX 600, jetting is right on for a pipe and air kit. Decent seat of the pants boost above 4000. Fuel mileage as stock/increased 3 mpg depnding on how ridden.
Magna vf750c went from fast to wicked fast. I recommend this to anyone with a magna. Open up your exhaust and add a k&n air filter and you'll have a rocket!
Dynojet kit woke up my ride! Super smoth throttle now. Thank you!
Well-made product. Came with everything that was listed.
This kit works! I chose the third level jets in the kit for my 2002 Honda VT1100C Shadow. I did the hole saw treatment on the mufflers and installed a K&N filter before I re-jetted the carbs. The bike ran well enough but in my opinion was weak on acceleration and back fired constantly whenever I would roll off the throttle. It also took forever to warm up on colder days. Installing this kit is not for the novice but the benefits far out weigh the hassle if you can D.I.Y. Seat of the pants tells me this thing accelerates much better, warms up faster and now has a nice deceleration note instead of bangedy-poppedy, pow pow every time I slow down.
Good product @ fair price!!!!!!!
looks to be what I need
I KNOW J&P SAID TO CHANGE THE JET KIT FOR THE YAMAHA ROADSTAR 1700 WHEN CHANGING THE PIPES BUT MINE ACTUALLY RAN BETTER WITH THE STOCK JET KITS. I HAD TROUBLE WITH THIS JET KIT. TWO THAT CAME IN THE BOX WERE PUT INTO MY BIKE BUT IT NEVER RAN GREAT. I ALSO HAD TO USE A LOWER GRADE GAS SO IT WOULDN'T BURN SO RICH. THE JET KITS FOR MY WIFE'S 650 CUSTOM WORKED GREAT THOUGH. I GUESS IT HAS TO BE YOUR CALL. I STILL LOVE J&P.
GREAT PRODUCT, BIKE RUNS GREAT
Great product!! Easy installation!!!
Worked great on my Honda VT750DC Shadow Spirit. I removed the snorkel from the airbox, added V&H Cruzer pipes and used the 104/106 mains from this kit, 3rd notch on the needle. I'm at 4500 feet in UT and it runs much better than stock.
Great bolt on addition, a must with aftermarket pipes.
Dyno Jet kits are the best. Research has gone into their kits. Not overly rich like a lot of the jet kits, especially those packaged with aftermarket air kits.
Real simple and easy to follow instructions.
Easy to install with supplied instructions. No longer need to use choke to start when cold (so far in summer). Removed the hesitation and sputtering when carb is cold. Workmanship of the product is excellent. Highly recommend changing out OEM jet to a Dynojet jet.
Great buy easy install detailed instructions added 20 miles to the tank with exhaust purchase
Excellent procuct, easy install, much improved performance. Fantastic Customer service. Highly recommend, especially for aftermarket exhaust.
best kind, good job
Product worked perfect
Kit has Plenty of jet options. Worked great on my bike, after I had installed a K&N filter and new exhaust
Installed the jet and needle according to the directions and my cycle started right up and ran great with the default settings!!! Very happy with this kit
Easy to install with included directions. Noticeably increased the power on my Yamaha royal star.
Great kit, well designed!
Easy to install. Did this with a K&N replacement air filter. Very noticeable difference.
Just installed this on my bike last night. At first I could only get it to stay running without the choke on. Tinkered with it today and finally got it running after I adjusted the air fuel mixture screw. Kit called for 2 and a half turns out and I had to take it to 4 turns out. Haven't had a chance to take out out yet and see any improvements yet
Fantastic result from installing this on my 2005 Kawasaki Vulcan 800. Only thing I have to say is that if you don't have experience with hand tools and some knowledge of carbs, I would suggest you do some research before tackling it on your own. Only reason I dropped a star is because the instructions aren't very clear if you don't understand, however the product on my bike works phenomenal! No more choke for the coldest starts!
If you get a new exaust, get this. must have
