Hey everyone, im new to the board and also new to the whole powerful 4-stroke thing, so bare with me if you will. I just recently bought a 2004 yz450 and yesterday i had a lil crash with my bike and busted my clutch lever AND perch ... so i figured its time to get a whole new set and i found ASV ... so i was lookin through the products which they offer and got a tad stumped on which one i should buy... I was looking at the C/5 series, pro model perch, but im not sure whether to get the hot start one or the one with the added compression release ? what does the compression release do ? and does it work with my bike ? thanks everyone, sorry if this sounds a lil noobish but it is !
