Siezed Engine

Postby Barlow » Wed Jun 15, 2016 8:58 pm



I posted awhile back about the engine in my 75 Wing being seized.
Well with some info from the members here it is now turning over with the tranny in 5th gear and using the rear wheel but..............
With the tranny in neutral, when I try to turn the engine over with the kick start lever it won't budge.
Any idea why and how to fix that problem ?
The bike has been sitting for a long period of time and I'm thinking the clutch plates are stuck together.


Happy trails,
Barlow

I don't think the clutch disc seized or not would have any effect on the motor turning over,
I would be more inclined to think it has to do with rust in the cylinders, have you removed the plugs and sprayed penetrating oil in the cylinders and then work on turning it with the plugs out. If not I would try that, if it gets better then you would need to remove the heads and clean them out properly. are you sure the motor is turning when in fifth gear and not the clutch slipping allowing the wheel to turn

I used a 50/50 mixture of trans fluid and acetone which freed the engine.
When I turn the wheel I can feel the compression stroke even with the plugs out.
I've had the clutch plates stick when a bike is stored over the winter but was able to free them with the starter.
The Wing is not running at this time so I can't go that route.
I hope I can get the clutch freed up without any disassembly.
Looking for ideas.

seafoam in the oil might do the trick. you could even do a 50/50 mix of trans fluid and seafoam, let sit a few days and just keep rocking the wheel while in gear to get it all over the plates. even if it doesn't fee them up it won't hurt anything
also keep working the clutch lever as much as possible to keep changing the pressure of the plates in the basket
maybe pull it in and tie it tight to the handlebar to keep the pressure on it overnight

No, you are not. With the plugs out there is NO compression. If you are feeling that then it's a tightness in the engine, probably still the rusted bores.
If they have been that rusted, pull the heads and clean out the rust particles as well as change the oil. You don't want these particles circulating in the engine or you will have a bigger rebuild job on your hands.

'Impossible' is just a level of difficulty! The only stupid question is the one you didn't ask first!

I think the problem with your kick starter is a separate issue. Mine is also stuck/inoperable, but the bike starts and runs great otherwise. Have you tried carefully hooking up jumper cables and spinning it over with the electric starter?

This was suggested to me by another person so I think I'll try it.
Interesting to know about the stuck kick starter.
I'll have to check into that also.
Will let you know.


Happy trails,
