Also to finish things off when we measure the intake clearances it was showing 0.80 mm, could this be the valves bent or just from general bad maintinance that its got this far?
We re shimmed anyways but all we can get is an occasional backfire like timing is out.
When we had it apart we did have a look at the head and everything looked ok but we never had valves out and there was no obvious marks on the piston from hitting.
Im also aware that the oil/filter and valves should have been checked when we got it but this one never.
Edit:- ok got bike running but it was 12 pins in between not 13, does this mean chain has stretched?
