Saving Old Seagulls

Couldn't measure compression when I got it as head was off ... and goosed. I think I have sourced an early gasket so hopefully skim wont be necessary. Still worried about thinness of outer top of cylinder .... could I repair with chemical metal just to get surface area for gasket seal back?

Seems to be 32 thou. Jet is a 115.

Sorry Charles not had a chance but will do it Fri night or sat and post. Thanks.

Charles, Not sure what measurement you mean but have attached photos .... as you can see there was a fair bit of corrosion within the jacket with the top part of the cylinder greatly thinned. Inside surface of bore looks fine and piston running smoothly.

Thanks Charles, I held a steel rule on edge across the bore but couldn't even get a 2 thou gauge in between, the motor is a 1987 KL. On a related point the outer edge of the top of the bore is thinned down to a couple of millimetres due to corrosion within the jacket ... will this be enough of a fac...

Thanks, I will give that a go and thanks for the Loctite spacer tip.

I have removed these before using a bodged up pulley holding tool made out of a garden hoe but .....How are you actually meant to slacken / tighten the flywheel nut on an electronic given you can't hold the flywheel from turning as it has a cover and you can't take the cover off without removing the...

What changed to require a different head gasket between 1988 and 89 on the K & O?

That looks like the job Tam, Cheers. Ian

Hugz. The curlew one looks like an altogether more fancy arrangement ..... wouldn't like to try and botch up one of them! Charles, Thanks for the info. I spotted a pick in the spares book .... it looks superficially like a fuel tank brass blank plug ... it wouldn't happen to be the same size would i...

Only mystery now is that water spray nut thing. Will look up the spares book, might still be able to buy one. Arbian

That's great, thanks very much for your help. I should be able to have a crack at making one now. I guess if I could use stainless it might last better, I hear they had a tendency to corrode badly. Thanks again Arbian.

Grand, Looks same as the re made ones. Can you tell me which flange hole these line up with? Thanks

Thanks, I couldn't figure what that hole was for. The image on the main site of the re made ones had a hole in the tube part way down, does the original have this? If so how far down and what diameter. Cheers Arbian

What is the serial number and what parts are required. As Keith says it's a common motor so you can probably get hold of the more expensive bits 2nd hand and buy the plug / lead / cables etc new. If you don't need it now you can bide your time and keep your eyes peeled for the necessary bits .... no...
