Breached head gasket!! #3 cylinder

I have no steam exiting the right exhaust which is the culprit, just sooty water/ coolant which will drip from the joint . This is a modified exhaust not stock. Bike runs great. No visible water in oil or radiator but….. the coolant does seem to keep lowering in the overflow tank. I’m suspecting...

Compression test and all 4 are exactly at 150. I suspected a blown head gasket since I will sometimes have liquid dripping from right tailpipe. Wouldn’t I have one plug hole read way lower if there was a blown gasket?

Ignition control module 85-87- gl1200

Price reduction big time if anyone still needs this.

My rational was equating a practical approach. I can remove and replace another engine faster than replacing the heads…. But I have to admit, I did consider a head swap.

Okay… swapped out engine and just got another engine in frame. Breaking news!!! I realize each situation is unique but you have to hear this one. This engine had sat outside with spark plugs in and coolant in radiator. Upon draining the oil appeared okay. I changed filter and oil and to my...

I really think that all parts were previously removed and not put back correctly regarding the rocker , springs and such. It was not the water pump.

Working on spare engine. The good ole water pump fix. Getting closer!

Okay….. I have a donor engine already removed from a bike sitting on my shop floor. Cylinders are free but….. there is some rust inside one intake and on valve. I soaked with pb blaster and I’m hoping I can still use this engine … fingers crossed.

Things are going from bad to worse… some numbnut placed the incorrect bolt ( smaller bolt at very bottom of cylinder head) thus cracking the bolt hole on the engine block. This explains the slight leak it had. I don’t weld and I’m not sure jbweld could fix this. I have an extra engine and might...

Here you can clearly see how the rocker is pushed up against the head due to the rocker arm/ rod not being centered. The other pic shows the adjacent rocker in the correct position. Never had this problem before.

I'm learning.......You have the valve rocker arm that slides through the rocker. The valve rocker arm is off ... almost seems like its worn. I will keep checking. I've read somewhere of a collet that must be re-centered to fix this. will keep checking the manual

Let me get my parts names correct here. The rod that holds the tappets is out of wack thus pushing the tappets too close to the outside of the cylinder head. I have extra heads and can clearly see the difference. This is causing the slack hence the tapping sound. I will revisit the manual and...

I was checking that and the rocker according to the manual and it appears that the rocker has moved so much that the tappers have pushed back into the cylinder head … weird. I will have to get a pic

Right head off. Pistons and wall look good. I have a couple of spare heads in good shape. Will just use those.

Geesh!!

Took valve covers off and found this. Need your help, what’s going on and can it be fixed? Bike is 86 interstate

Well…. Just now have some days off and will take a closer look. I thought it was the water pump but I could be wrong. I poured seafoam in oil , will take it for a short ride …. Drain oil then add fresh and maybe that will quiet it down. Will keep u updated

15 years ago I was bored during the winter months and started tinkering. Fast forward to the present and I have redesigned some wings and kept some stock. 15 bikes later I’m still building these things and enjoy every minute of it. Your call , I’m wrenching more than I ride and that might...
