I am using a slow jet#35, needle on second position, main #400(cylinder was modified by MXT and carb bored to have more top end) and 1,5 out AS.
I am going check for any air leak on Boyesen RAD valve and between the carb and the air box.
BTW the last top end was done by myself and maybe could be wrong regarding throttle routing cable.
Is it possible to give any hint how to route that cable in the right way ?
A lean main could also make the engine idling high ?
Thanks all for your help.
I had a problem a few weeks ago. I had not been riding for two weeks and during this time it had got colder in the air. So i could ride normally one lap then it boooooowah on WOT and had a very high idle when i tried to slow down. Then it went away when i rode slow then came back again. The solution was a 188 main instead of 180, works great now.
