Hi guys,

Got back my JJ3000 and ran a series of test runs. (You can see the history of that engine in post# 2761)
The engine start and run hassle free, but can't go over 110K. (it should rev up to 115K)
Fuel line is free, with a new clean filter.
Temps around 650 ~ 700c
Battery O.K.
Settings and parameters are O.K
I know it can be due to poor balancing or bad bearings, but both seems to be O.K
Do you have any idea why it happened ?
