Recently just purchases a used 2002 beartracker off of craigslist. The first 5 or 6 rides on the thing (approximately 1 Hour each were great; everything worked as intended. The other night I go to start it up idles fine but when I give it any bit of throttle the engine will just bog and stall. So rather than rebuild I just bought a new zoom zoom carb and the beartracker is still bogging?! My boots are brand new, no air leaks. What gives?

 

Take the float bowl from your original carb, remove the jets, blow it and the jets out with compressed air and re-assemble. New carbs have to be set up, it is always easier and cheaper to clean out your old carb than to fit new.

 

the old carb was cleaned and still gave me the bogging issues. Thus i bought thr brand new carb and the issue is still there.

 

How does atv run with the air cleaner lid on the box? also this atv doesnt have an accelarator pump an will get some bog when accel slow...Put lid on then see...with the lid off the engine gets an lean mixture from to much air an not enough fuel.Good Luck

 

Also with the aftermarket air filter an the lid off give engine an very lean mixture..double whammy

 

Lid has no effect. Same issues. Checked the jet sizes as well same in old carb as new carb.
Its weird I put the old carb back on and it worked perfectly. So 2 hours later i decide to take it out again and its back to the bogging. Its defentely NOT a carb issue. Possibly electircal ?

 

checking charging system cold and hot

 

How did run with old factory air filter

 

Air filter is def not it. Had about 7 hours witht the new filter when she was running great. Ever since i took it out on a really wet night the bogging started.

 

k just asking trying to help
