Unhappy 1997 Polaris 425 Magnum Problems
New top end pistons valves no trying to start and gas is coming out of the exhaust what would be causing this? Any help would be great.

Thanks

Plated links DONT have to align with dots along as cam index pin as in your picture is at top dead center (appears to be) and BOTTOM sprocket mark lines up with case mark at the same time!

then what could cause gas leaking out of the exhaust? Valves are brand new with a new seat job?
