3AJ update, any ideas?
The last few attempts to start the bike have seen it backfire hard enough to blow the carbs off their rubbers!
It started and ran fine yesteday (under it's own battery power) but when we went to start it again, it wouldnt play ball. Valve timing? the chain was zip tied to the sprocket before the work started, and hasnt been moved. Could having a much less worn cam and head mean the valve timing should be re done? Its not getting the best spark, but getting sparks and petrol.
Any Ideas?
Thanks
Pete
