need timing instructions for an xr80r?

[RST295]

I've got an xr80r motor on a go-cart frame and I need to know how to put it in time? If anyone's knows feel free to let me know plz. Thanks RST295

Do you know if that engine is the same design as the 50? I've got a couple of pictures from when I put the big bore kit into my 50 I could post if they are.

See if this looks familiar-

Crank Timing
Cam Timing

Line up the marks as shown on both the crank (flywheel) and the cam chainwheel. The cam lobes will not be depressing the valves, rather, they will be off the valve stems, pointing away from them to some degree (not sure to what degree, however, but it's hard to mess this up). Good luck!
