timing?

[royxc800]

My mods are as follows. ported ,slightly smaller cool head domes, Boyesen reeds,30mm flat slide mikunis, Paul turner midrange pipes. I have the adjustable timing plate and was wondering if I should retard it or advance it and how much? I do mostly woods riding. Thanks Mike

I would advance it +4 degrees to give you more bottem end. Also, you might have to run a higher octane depending on your elevation and dome size.

Advance +4 and your good.
