heres my progress of the rebuild of my act 500r. my main question is exhaust. it looks as if the cr 500 gnarly pipe with fit right it with no mods. is this true? do you guys usually use cr500 exhaust with atc silencer? also whats the best way to do the cooling lines. i would like red hoses but i probably have to buy a couple kits to piece together. any input would be appreciated. or if you have any parts for me let me know. ill keep updating as build goes on.
