Guys I need some insight or ideas here............I have the head off the new bike, and am trying to remove the cylinder I have removed all of the nuts and bolts from the cylinder base.
Three front base nuts
Two rears loosened up as far As they will go and the four through bolts, but the base had to have been sealed with some kind of glue or sealer because the cylinder will not budge. Have I overlooked something simple? I mean this thing is solid to the cases. I have pulled, swore, used a rubber mallet and cussed more, but this thing is tighter than anything I have seen. Any ideas as to what could have been used or better yet what to do to get the cylinder off without damaging the cylinder or cases. Someone out there is surely to have had a similar experience?

Sometimes you can use the 2 tall nuts still threaded on the rear to push the barrel away from the case. Turn them equal amounts, a little bit at a time, and they should push up on the underside of a lower fin, and you should be able to break the sealer - whatever it may be. From there you can work around the barrel, lifting equally. Do everything in your power NOT TO GIVE UP and wedge a pry bar in between the cylinders and case deck.
 
Holmeslice, you are my new hero, funny how the easiest answer is right in front of me and I couldn't see that, great trick, thanks a million.
 
Yes, made my whole day worthwhile. This is the reason I like this forum so much. Being a novice mechanic, I can get decades of accumulated knowledge, tips, tricks, advice and brow beating when needed, thanks again.

Did a lot of head scratching on this too and banging with rubber mallet. Using those nuts as lifters worked a treat - simple and effective. Cheers,

Just be aware that as those nuts get to top of threads they can spin in place and bugger the initial threads to be a bugger to get started again. Glad you got er off.
