closed petcock= highly elevated rpms?

[hannesd]

so with the fuel bowl running lower and lower after closing off fuel, my engine starts racing very high... could this mean that i'm running rich on my PJ?
got 40 in it now...no head mod, nfairly new piston, all good condition engine.

just noticed this last weekend.end of the ride, put my bike against a tree (no side stand) and shut fuel off and after 15sec rso, it happens...

thanks for helping me with this..

ciao, Hannes.
