Woke up the bike

Comments On Aug 20, 2015:I was having serious cold start issues on my girlfriends bike. Between this and a K&N air filter it starts up fine on about the third kick from cold. It would get 5 stars if it started first kick when cold. It is important to note I rebuilt the carb on this bike with this jet kick after the bike sat for several years when the P.O owned it. So maybe all the bike needs is some more hours on it. But once the bike has been ran it starts quick every time and has added a few ponies over stock. Much more enjoyable to ride, and no more stalling makes her much more confident in her machine and allows her to push her self knowing the bike won't be the problem.

Jetting made easy!!!

Comments On Jul 30, 2015:I have a completely modified engine, a duncan racing exhaust and run a open air box, this kit had a extremely helpful jetting guide. I followed the guide and had perfect jetting on the first try! Lots of extra jets for different setups and elevations.

Improved throttle response, and overall power

Comments On Jul 04, 2015:Awesome product. Would buy again. When first bought, I ran the stage 1 settings. Big difference over stock carb settings. Modded my intake and went to a stage 3 kit. Jetting suggestions were very accurate. I had to fine tune to actual bike specs, but the guidelines made it very easy to get dialed in.

Woke this little quad up from the dead!!!

Comments On Mar 27, 2015:I bought my wife a 250z quadsport for Christmas & wanted to tune it up a bit for her. So after looking online at alot of reviews, the quad kids were saying that the DynoJet kit was a must. They werent lying! First I cleaned the carb & installed a Moose rebuild kit w/ the oem size pilot jet to freshen things up. Then I installed the DynoJet kit (which was super easy) to our sea level & mod specs which was under 3000' w/ the airbox lid & baffle removed. I then had to order an adjustale air/fuel screw for a DRZ400 from Keintech to dial it in. After all that, this little 250 rips for what it is & was. I was very surpised at how much more rev she had. Its actually a fun little quad now & great for my wife. The only issue I have is that it doesnt come w/ a new pilot jet. Its just 1 more small jet that would complete the kit I think. They come w/ carb rebuild kits, so for the price they could throw it in.
