just like the title says, how do i set the valves on an 1986 hond 250 bigred 3 wheeler

It is very simple.

Remove the tappet covers from the top of the motor. setting the timing to top dead center and check the gap with a feeler gauge. If you have never worked on a fourstroke you might want to by a service manual. We sell one that covers ATC250es/sx and trx200/250 84-87 for $29.50

You can find out if you are at TDC by removing the timing plug on the flywheel side of the motor and checking the markings when turning the engine over, or you could remove the spark plug and feel the compression (with a finger) as the piston comes up, then you'll know you are at TDC. When I check my 200S valves I make sure that there is some play in them but normally do .007mm for the intake and exhaust. You can also head over to 3wheelerworld.com for some other how too's, there are plenty of smart guys over on that forum as well that can help you out. Good luck!
