Don't know what to do
 

I have a taotao ata110-d quad... it starts and idles fine... when I give it gas sometimes it bogs down. Which I'm sure that's fuel filter or air filter... what I don't know is some times like if I'm going up a small slope the rear end will start shaking really bad if I lift the rear tires off the ground and give it gas it stops.. any ideas what could cause this??

The bogging is more likely to be dirt in the carb. Is the chain and sprockets in good order and adjusted. Check the rear axle bearings for play too.

Okay I'm going to check that out after work today as I'm changing the oil I appreciate the feedback and hopefully we can get this fixed
