PMA Rotor Timing Marks

[Scotchmist]

Hi all,

I've presently got an RD350 PMA fitted to my bike but never got around to making timing marks on the flywheel. Can someone confirm that the only mark on the flywheel is for TDC? I'll also need to add timing marks to the engine cover. Please could someone confirm how many degrees advanced from TDC the 'fire' and 'advance' marks should be. I'd also like to know whether the timing can be retarded very slightly to improve bottom-end torque. If so, by how much?

Thanks.

The traditional method here is to have a single mark on the flywheel, with the 3 other TDC, idle Fire, and advance marks on the case.
