Somebody must have installed one of these, Anyone?

 

doesn't look to good to me. i'm waiting for another option.

 

SPEEDYDOG5-my wife had the first powroll 250 ex that was built because they actually used her quad as a 3 month r&d project.the 250 ex is of course limited by its small motor but if you do the powroll kit with the pipe that they make for it you will be very pleased with the results.the powroll kit feels like probably a 30 percent increase in power just as a guess.the one thing that the 250 ex could use is a rev box to up the limit but you can compensate for that by going to a taller tire for a higher gear ratio.the dependability of the powroll set up was about as good as it gets with no problems at all and we had that quad for about a year after powroll finished it and then we sold it to get my wife a bigger quad.if i can answer any more questions for you let me know and i will help if i can.
