i have a cr500trike. its very simple. mild porting, 44mm lectron, ftz pipe everything else is STOCK in the motor it just dosent have the top end hp. BUT its a ROCKET out of the hole i use a +14 arm and 10 paddle rippers its explodes out of the hole.. but just wont run out far enough. to beat fast banshee's/ now other simple stuff oh yea its got that down.. i really would like a better head thats set up for alky AND a newer BIG pipe desing made for dragging.. but so far its been super dependable and fun to ride..
