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.

klx250s

Comments On Oct 03, 2014:I had to rejet my carb to run well with the new FMF power bomb header and muffler. this kit had a nice mix of jet that did the trick. I would also recommend you get a aftermarket air filter to complete the power boost !!
