Yes the oil system should be blanked off securely to stop the motor drawing air. As far as the jetting goes its generally accepted to go up 5-10 points on the main to compensate for the oil that is reducing the amount of fuel going into the motor thereby weakening the fuel mix.

I would change the jets ... as the oily mixture would require a slightly larger main jet .. I would guess you have done the obvious .. ignition timing & decoke to ensure the rest of the motor is running ok ... but also if you have not blanked of the oil intake into the carb for sure the motor will run weak Link to comment Share on other sites More sharing options...

I should have read the intro in the noobs section properly that said you leave the bike for years at a time, ah you didn't write one. Link to comment Share on other sites More sharing options...
