The bike will easily pull me (200lbs) up ~ 30 degree hill when cool, but wont pull daughter or me up hill when hot, any ideas or experience with this?? is this the clutch slipping? its a centrifugal clutch , rpms dont increase when going up hill but feels like the break is on, but is not. Any ideas?

 

are the brakes reacting normally and not sticking? so the quad has gears for shifting manually/semi auto or is it an automatic? if automatic, pull side cover and check drive belt for wear.

 

brakes are not sticking. It only happens after riding ~ 20 minutes. automatic , no reverse 2 wheel drive TAO TAO ATA110b.

 

i'd check the belt to see if it is wore down inside the sheaves.

 

How hot does the engine get? Way too hot to touch?

 

ill check the belt ...BUT why would it only lose low end when hot due to worn belt?

 

yes engine is pretty hot . but is air cooled

 

Im wondering if its getting so hot the engine is sort of vapor locking... basically burning the fuel before it gets in the engine.. All of these are set up very lean which makes them run hotter than they need to..Has the quad done this since you got it?

 

it just recently started doing it, but bought it used, and she hasent really ridden it much for as long on hills like lately. can clutch start to fail when it gets hotter when toward the end of its life, its an automatic, centrifugal i assume

 

I believe you can adjust the clutch on the side is a nut with a threaded rod comming out of the case, the rod has a screwdriver slit cut in it. Crack the nut loose lightly tighten the screw till it stops back off a 1/4 turn and lock the nut see if that helps also change the oil.
