Oops. Now I need a manual for pushrod 250 head removal

[KirkN]

Sigh. Like the title says....

Started my Baja X250 and while it was warming up, the throttle stuck open. Took me 4 or 5 seconds trying to get the throttle to release before I killed the motor. Tapped on the carb in the area of the throttle slide and it released. (!??) Started bike again, and carb again stuck open. Wasted 4 or 5 seconds dicking around before shutting it down.

I didn't think it was really revving up that bad, but now it won't start. Did some rudimentary troubleshooting and could hear the motor 'chuffing' back thru the carb and have discovered that motor is only making 30psi compression.

Sigh. Must've bent a valve.

I haven't yet done any disassembly, but first up will be pulling the valve cover and having a look. See if I see huge excess valve clearance on the intake valve.

So, anyone got any pointers on head removal? This is a pushrod 250 motor.

Anyone got a line on a new intake valve and a head gasket?

Sigh.
