i have a 99 wr400 and i took off the valve cover to inspect the timing chain. it was all fine so i put it all back together and now it backfires when i totlay let off the gas. the only other thing i did was take the header pipe off and i was wondering if i didnt put it back right but i think thats kinda hard to do. Anyone know the problem?
