i dont know much about them but ive read a couple times here that there worthless that the gains are minimal if any.

they give you a little better throttle response, they are supposed to give you a degree or so of timing advance and increase spark duration, i doubt it does nothing, i can hear it when im warming it up as in before/ after sounding, but it is def hard to feel in the pants....

wouldnt spend any money on it... if you really want a roost boost for a 250R! go to Dave moore racing he has one that is dyno PROVEN... not hear say... for a 350X i havent seen a rev box or anything EVER... so who knows

I've only run them on 2 strokes. The last one I put on my 89 quadracer250. I gained some throttle responce and it seemed to start easier. Top end seemed to creep up faster also..............

[RideRed250R]

Dave Moore Racing is a big 250R porter for drag racing.. he offers about anything you need to get your R to hit the 70+ mark ... hes got some bitchin stuff...go to davemooreracing.com, look around... i have one cylinder with his play race port job and all i can say is WOW on that one... i just gotta have it resleeved i had it bored to 272cc and then the top end went out (damn olds hill) i would go to him for high numbers... i personally also like JM motorsports.. they have my 310 kit over htere right now... 60RWHP on pump is what they are saying

i just got done checking out the sight looks pretty kool and all the prices seem pretty reasonable too. can you still run pump gas with the play race porting? or do you have to run or mix race gas?
