Hi,
I have just started re-assembling my XS2 after a full strip down and a few modifications and have got a problem setting idle speed.
The manual says the best way is to run the engine, remove one spark plug cap and set the desired idle speed then reconnect and do the same on the other side. I have done that, setting idle to about 1000 rpm, but as soon as I put the second spark plug back on the idles races off to about 3000 revs.
I have repeated it a few times and it always does the same thing. On one cylinder it will run around 1000 but as soon as the second one is reconnected it revs away.
I have stripped and cleaned the carbs, all original settings were used. I have also fitted air filters from Mikes XS. I am pretty sure everything is airtight.
Fuel flow seems to be okay although a fair bit of air collects at the top of the right hand fuel pipe. The carb link pipe is always full.
Has anyone got any ideas?
Many thanks
Tim
