Bogging down high revs/full throttle

PostAuthor: scottyr6 » Sat Nov 11, 2017 4:02 pm

Hi,

I've noticed my 535 hesitates a bit at high ish revs under full throttle/hard acceleration. The bike is standard apart from de-baffling the exhaust. Could it need bigger jets in the carb? If so any tips on what size?

Thanks,
Scott

Maybe, since you removed any baffling and increased air flow. It could have leaned out the mixture. Could just be changing jet needle size or height...But, I'd eliminate any possible air/vacuum leakage first (easiest). Could try spraying with carb cleaner around all joints /hose fitting.. holding at higher rpms.

Check your plug color. If they are white, it is running lean. First thing, try turning your pilot screws 1/2 turn out..... Then run it and check the plugs again. Could also be a low float setting and you are running out of fuel at high RPM>
