Recommended Posts

hi guys

i recently got me a 07 drz 400sm and i have a few questions for you..

its got a jd jet kit in it also it has the 3x3

here is my question..

i went out today and got a fmf powercore 4 slip on..

being that i got this bike from 20 min away from my house is installing this pipe going to effect my jetting?.. im not to good with carb stuff..

also i was curious about horse power gains and i would like to see some dyno results..so i can see where im sitting..

any help would be greatly appreciated.....thanks

slip on will have barely or no effect on jetting because it isn't freeing up much exhaust flow. That's more of the head pipe on these bikes. So, little or no power gain. Get a full system! Go with the MRD pipe and let eddie at it. http://warnekedesign.com/mrd-racing/pipes.html
