Timing pics for WR400...Please help!

2 posts in this topic

Bike is tough to start. I use the choke. Once choke off, struggles to hold idle and must take care to apply throttle so will not stall. Lots of popping while riding.

All free mods (wire cut, airbox lid out, throttle stop out) plus aftermarket header and White Bros E2 exhaust.

I ride in CA. 0-3,000 agl.

Timing marks tough to line up just right.
