Ah my beloved GS still hasn't been fixed. I fixed the problem with fuel (no spring in the vaccum / tap causing fuel to flow when engine off, ouch).
Anyho'. Acceleration is still poor and general tickover is haywire. Max speed about 80mph :(
If I unplug the left start-plug lead the revs are going up and down and doesn't sound good at exhaust, like minor backfiring. Not smooth running.
If I unplug the right start-plug lead the left cylinder is running smooth EXCEPT if I rev to say 6000rpms and hold it there while in neutral the rpms constantly become lower until the engine dies.
The only thing I havn't had checked yet is the valve clearances. Does anyone know if this could cause any of the two problems?
Please help my poor GS this Christmas :kiss:
Yes check the valves. Such different behavior between cylinders means there are leaks or your carbs are way out of sync or tune.
Thanks, I had the carbs tuned recently but I had to readjust the right carb needle as it was too low and no fuel getting through. Could have upset the balance.
