when i stand up on the grab bar and do a wheel on a shaft driven the quad wants to go to the right but when i do a wheelie on a chain driven i have no trouble keeping it straight, what could be the prob.

 

Check the stagger of the tires. You have to check the stagger not just the air pressure. The quad with the pull will have stagger in the tires for sure.

 

this might be a stupid question but what is a stagger

 

Sorry about that. Stagger is the circumference of the tire. It's what the NASCAR boys do to make there car turn. If you have a bigger tire on the right rear it will make the car turn better in a left hand turn.
To check for stagger some people just check the air pressure. This is the wrong thing to do. The only way to check for stagger is use a flexible tape measure or stagger gauge. In other words, snag the tape measure from your girlfriend or wife (don't let her catch you doing this!!) and wrap it around the tire in the rear and check it. Go over to the other tire and check it. The measurement should be even. If not, you have to put more air in the smaller one to get the same measurement. Once this is done your quad will go straight.

 

thanx i will check it out when i get home.[img]i/expressions/face-icon-small-smile.gif[/img]

hey i checked it and the are the same on bother tires so what else could be the prob.

 

Try a decent pressure gage that is calibrated to 0-5 psi. On low pressure atv tires, a .125 psi difference will have you doing circles within a football field.

 

On a straight axel with shaft drive; thats it.
Just add two or three psi to the opposite side that it pulls to..........it'll turn, believe me.

 

smart thinking there
