Mr Freebird.......looking at your picture above......it shows you have equal lift at TDC.......therefore your cam is retarded........rotating the cam clockwise one tooth is advancing it 7.5 degrees........this is at the cam, so at the crank it is half that......3.75 degrees which is very close to what you need.......so rotate the cam clockwise one tooth........however, you might find the front cam out as well........I know it takes time and a bit of head scratching looking at the degree wheel, as from TDC you need to put a mark 50 degrees anti clockwise to show TDC on the front cylinder.......if the front cam is retarded, then you can alter that one at the same time.......you may not know that the crank gear has 5 keyway slots in its center so the overall timing can be adjusted........normally a small puller is used to extract this gear off the shaft once the thin E80 nut is removed.......this keyway adjustment allows overall changes of 3 degrees per slot at the crank........if your front cam is out, it may be a simple case of altering each cam.....or removing the crank gear and relocating the gear via a different key slot to alter the timing........keep asking away........if you intend on riding this bike for some miles, I might add that changing that alloy large idler gear to a new steel item is the norm.........the alloy gears work ok, but tend to readily shed fragments of alloy which spreads nastily throughout the engine and fills the oil tank........not good and oil tanks are difficult to clean especially whilst still attached to the top of the engine........Good luck with it........Cheers........G.
