I have one that seems to lose power as it warms up. I'm thinking the brakes might need adjusting. When this loss of power occurs, it's also more difficult to push. If this is the case, how do I adjust them?

 

their's no adjustment on disc brakes.

 

any idean on loss of power then?

 

I had a similar problem with my SunL SLA-110KLB. When the engine got hot, it would lose power and it also was hard to push. I thought the rear disc brake was locking up or there was a problem with the trans. The problem was my son was driving the quad with his foot resting on the foot brake. The rear disc brake was very hot to the touch and I could not move the rear wheels. After it cooled down, the quad ran normal again. Now that my son rides with his foot off the brake, no problem.
