Ok, so i had a head gasket blow out last week apparently from the head bolts either not having been torqued correctly or just good ol fashion vibration. So i dis assembled the head changed the gasket. Now i have good compression on both cylinders good spark on both cylinders but the clinder i changed the gasket on is still not firing. The bike will start if i hold the choke out and the rear cylinder exhaust gets good and hot while the front cylinder exhaust stays cold. So my question is, if i somehow screwed up the pushrods and put them in the wrong place would that cause the problem or would doing that lock up the motor all together? also is there something that i may have disconnected that could be causing this problem?

 

The exhaust pushrods are marked with three pink bands and are 10.800 in. (274.32 mm) long.
The intake pushrods are marked with a single brown band and are 10.746 in. (272.94 mm) long.

 

AWESOME!! So it looks like everything was put back together fine, i took the valve cover off and thats the order i have it in. But then what could be the problem with the dead cylinder? I have fire and fuel and compression! So whats missing?

 

I've put in a new spark plug that was dead before.
Could be a bad plug wire. Swap them on the coil and see if the rear fires and the fronts dead. (thats only if it still has a dual fire ignition system in it).
Could be a bad coil. You'd have to test that by the specs in the service manual.
