I'm trying to resurrect a 94 R1100RS that I bought as a project that had "a rough idle" as stated from the upstanding citizen I bought it from. Turns out, these bikes will idle roughly when one cylinder had zero compression due to bent exhaust valves from over revving. Who knew? I took off the heads and had the valves checked / replaced along with a valve job on all 8 since it was a good time.
My problem is this: While attempting to reinstall the heads, I noticed the rocker arm on the right side head exhaust was tight when adjusting the axial gap. Everything is loose from the rebuild and nothing is set yet. The other 3 rockers were all "loose" compared to the this one. I popped off the retainer at the bottom and the screws at the top to pull the rocker off and have a look at the rocker arm shaft and it's stuck in the head some how. I was able to pull the intake rocker and shaft out no problem on the same right side head. When I put a punch into the oil hole at the bottom of the stuck rocker shaft to rotate it, it only travels maybe 30 deg and binds. The intake rocker shaft would travel freely side to side as far as I could turn it.
This stuck rocker arm shaft is the same location as the bent exhaust valves from the repair stated above. I'm disappointed the guy who put this together thought it was ok, it's clearly not. I understand the same forces that could bend the valves may have affected this shaft and I'm fine with ordering a new one to replace it. But, how do I remove it without damaging the head, valves, cam push rod, etc.? I did some "mild" beating on it trying to get it free.
