Hello got a prob rode my qt into the ground always wide open, 40 miler a day and need to do high 30's atleast. Put a uni filter on my qt50 and three days later bam, now I need a new cylinder and was wondering what the feed back is? yamaha part vs. brandx. I need to go fast, but not break, was going over 30 really wanna do 35 consistant. Did my uni filter have something to do with that, because i had to put the air screw in all the way.
