cylinder head removal

[Baycruzer]

That's a loaded question.

The engine I tried to remove the head from is on my garage floor, and going to the metal recyclers on Tuesday.

The engine for my motorcycle is still in it, I haven't tried to take it apart yet. I was considering removing the head while still in the frame.  Randy is saying that overheating is usually what causes the valve seat to come out. There are other things that happen to the head in that situation. The holes shrinking around the studs could present a real challenge in this case as well.

Something else Randy said kinda has me worried now. when I got the bike I was told it lost power. one of the first things I checked was the valve clearance. All of the valves were tight, 7 of the 8 exhaust valves were riding the cam when closed. So the possibility is the seats have sunk into the head, lets hope the last engine hasn't been so roughly treated.

Ok... So the head that you wanted is the one you can't get of?? Do you have a sawsall, or a grinder?

It might be time to just bring everything over so we can get things sorted.

Don't junk that engine yet, you might need something from it...

That's what I'm sayin... Don't give up yet...  "if there is a will, there is a way"

Another thing, that old engine might be good for the FJ cause, especially since someone just ventilated a crank case...

Because Chris is going to make an attempt at Bonneville and is now going to have to install the engine he planned on using at Bonneville in his daily rider, so now he has to sort out another engine and your spare stuff would work great for that.

Do not scrap that engine...

OK, so I still have all of it.

The engine with the head stuck on it, I checked the numbers and it is an 86 1200. The cases had been separated when I got it, all of the transmission has been removed, some of which is in the box of rusty parts. The crank, rods and pistons are still installed. can't promise condition.
I did break some of the cooling fins on the rear of the cylinder block, left side. I still have the pieces, could be welded if somebody knows how.

The head seems to be stuck on 2 of the studs between the #1 and #2 cylinders. At this point I'm going to leave it alone. offer it up to see if someone can use it or wants it.

OK, so I grew a hair and pulled the head off of my motorcycle engine. What a completely different experience this was. All it took was a light tap with a rubber mallet to loosen the gasket and lift it off, no damage, no fighting.

Next is a trip to RPM to see if it can be fixed and to drop off the spare cases.

[mikedastonfj1100]

Awesome.... Let us know how it goes:)

[Baycruzer]

Got the head to Randy. He says caused by PO not adjusting the valves, he can fix it.

[mikedastonfj1100]

Great news he was able to fix it:).. I've noticed with that type of valves u have to check them once in a while... Hopefully he does fix it:)...

Picked up my head from RMP yesterday. Randy did a beautiful job on it, it`s now the best looking part on it. Today I put on the head and reassembled the rest of the bike, got it running but for some reason the carbs are all out of sync. Must be because I synced them with the three burnt valves.

[Baycruzer]

Sorry it has taken so long to get back on this.

I have put the bike back together, cleaned the carbs, bike runs like a champ. I am super happy with how it has worked out. There will be some new questions asked soon, I will start a new subject for them as they are not related to this one.

thanks for all the support, lets go ride!

Right on!
