u/Additional-Orchid735

Previous ride at the week I had no problems and jetting felt almost perfect. Yesterday I got several runaways after longer WOT sections when letting off the throttle. After stalling the bike with gear and restarting, it felt quite normal immeatedly but didn't want to continue hard pace anymore - just ride back to pits. Difference was that at week track was dry and now wet-ish. Deep sand.

I have recently went down slightly with main jet, but only 170->168

-Left side crank seal didn't look too bad but changed it anyway.

-Went back up with main jet.

-Pilot might have had some trash/water drop, not sure.

-With hot engine at track sprayed brake cleaner to carb/air boot/reed area etc with no effect(did not test crank seal with cover off).

-Can't feel any slide sticking. Positive clunk.

Anything else to check?

Was thinking to add UNI filter plugs to airbox for allowing some more air. Already bought 6-pack while ago but forgot what was my original plan.

Has anyone done it? Guess these need to be drilled on the dirty side of OEM filter but there's not much room.

Bike will be ridden in rainy/muddy conditions and needs frequent power washing
