Idle and over Rev!

[SmitAir17]

After the total overhaul of the front end, I was bashing again. However, after tuning, the idle was very inconsistent. I set the idle, and it would stay there a few seconds, then increase rpms a few seconds, then back to regular idle a few seconds....this pattern would continue. What could this be?

Question 2
It appeared to wind up sometimes before accelerating forward. The rpms needed to move seemed a bit high. Is is his a slipper clutch problem? If so, should I tighten it a bit?

Thanks in advance!!!

Sounds like you might have an air leak...
set it like they tell you in the manual go from there..

lsn could be too lean
after a pass what the the revs do if it drops to a nice idle lsn is good but if they rise your lsn could be set too leanor as stated before it could be an airleak

And tighten your slipper clutch like 1/16th of a turn.
