[SOLVED]Engine break-in....stalling...overheating?

Big update: Issue is fixed !

Installed #130 main from #125, engine run cooler in overall.

Did a little adjustment for carb sync and found the minimum stable idle is 1200 rpm (increased mass maybe ? (pistons are bigger))

Re-calibrated the pilot mixture when hot with colortune...


Now it's running fine


Thanks everybody!

Finally, i can nail the long thread


Best regards,

EDIT: oh yeah and no new carbs are needed

Man that is weird. That little jet change made for all of those symptoms? The oscillating idle and everything else? :blink:

Oh well, as long as it's fixed ! Still got half a summer to ride!

The oscillating idle

I think it was clutch related... i could hear the primary chain rattling on first gear at red lights.

Adjusted the slack (less than 1 turn out) on the clutch lever... rattling was gone and unstable idle...

Maybe a little bit of friction from the clutch kept the engine under a little skippy load and at trouble to keep the idle right...

That's my hypothesis

I started reading this lonng post and got to page 4. SIGH :dry:

Bout page two I'm thinking this poor lad is lean.

Two needle clip positions is alot. 4 pilot turns is alot.

The bs34's Bless those power makers, need a wide open throttle test repeated with adjustments to the pilot start out lean and open it till it pulls to redline the strongest. Those tiny jets :blink:

NEED FUEL?

WANT FACE LIKE THIS :woohoo:

how bout one for each gear :woohoo: :woohoo: :woohoo: :woohoo:
