i bought a yz 426 and from what i am told it has a gt thunder 460cc stroker kit on it, well when i went to change the timing chain and the cams i was in for a surprise and stupid me i threw out the old stuff and cannot find it. the problem i come across is the stock timing chain is too short, and reason being is there is a 1/4 inch riser plate that goes between my bottom casings and my cylinder (jug). can anybody help me find a longer timing chain? everyone i have talk to has never heard of this riser befor or a longer timing chain. HELP PLEASE!!!
