Added an 01 PW 80 to the family this Christmas for my son. Got the carb all cleaned out and running well. I am very familiar with 2 strokes, but not the PW, and not oil injected. I also don't have the owner's manual, the previous owner is looking for it. Is there a way to control, lean out the mixture other than the adjustment on the carb? Is it normal for the bike to fall dead with rpms in each gear, before shifting? 87 or 93 octane? brand of oil preferred, I normally run Motul 710 in my KTM? I would like to get rid of the mosquito fogger it is right now. It's cool to cold here and expect the smoke to get worse as it warms. Thanks.
