Oh poop

I should be okay doing it myself. I just need to keep in mind I have two herniated disks I need to be mindful of.

Thank you for the kind for the offer!

***edit*** bore scope in hand and 18 minutes until quitting time. I can't wait.

I hope that VERY HAPPY smiley is still in your next post...

All kidding aside, the valve seals are 30 years old, I had planned on changing the exhaust system anyway and Lord knows those bolts could break.. bolt removal without the head in place will sure make it easier. hey, look at it on the bright side (as I continue to tell myself...).

now to fish the mirror out of #2 cylinder which is made out of aluminum.

Did you find the problem?

[rustybronco]

Not yet...

I didn't see any valves hanging up, what I can see of the valve faces looks normal, nothing in the bore that was out of the ordinary like marks in the carbon on the pistons and nothing seen in the cam tunnel

late last night I got it to go around in the reverse direction for 2-3 revolutions and I've gotten it to go forward one time for 360+ degrees, but now it is back to 180 degrees lock to lock.

I'm getting my hopes up! because it is starting to feel like the cause might just be external.

on to the next step, pull the stator cover and have look.


I did get the mirror out.

[chuck hahn]

did you pull the cover?? Any ideas?

[SqDancerLynn1]

Have you checked it ?? I would bet the cam timing slipped !!!!

[rustybronco]

Unfortunately I can't get it to turn far enough to check the cam timing. but I think it's highly unlikely that the chain jumped, when it went from no problem the night before last, to how it is now.

tomorrows project is to remove the case saver and get that cover off.

it may take a little while but I'll find out the root cause of it.

Dale,
One thing you could do is remove the cams and then hold up the cam chain with your hand and try to turn the engine over. That would tell you once and for all if the blockage is related to the top end or bottom. One challenge with doing this is you need to get access to the cam chain tensioner, which may require removing the carbs. Never hurts to go though the carbs and freshen the O-rings so this may be your excuse now if you haven't already done it.

I've ran this thing through my head so many times, trying to think it through and the only thing that makes sense is valve to piston interference.

when I was shimming the valves I had to put up to a .2mm thinner shim and with 33K+ miles on it, most likely it never had the valves adjusted. so I think it is best to just go ahead and remove it, check the valves and replace the seals.

heck, maybe I can pretty up the head like yours while I'm there.

Seems strange that the engine turned over before but won't now. Did you check the cam timing, although I can't imagine how it could be off. If the valves are closing, and the timing is okay, the valves can't be hitting the pistons.

[chuck hahn]

you never told us what you found under the stator cover......all was good i am assuming???

[chuck hahn]

didnt happen to hit the shifter lever and the tranny is 'IN BETWEEN" gears and hanging up once in a while??????? sometimes when riding and shifting my shadow if i dont really slapm it into gear it will be like its in btween gears so to speak..i just jiggle it again and it shifts up and engages properly..just throwing that out there...

That's what stinks, it won't turn far enough to check the timing. I have to remove the cams to jerk the head anyway so that will give some insight.

I'd pull the cams and then check free rotation before going after the head. You'll have to pull the cams but you have to do that anyway.
