Seals for oil drain tunnels after fitting cylinder spacer

[JohnnyB12]

Hi to everyone,

 

Rule 4. Don’t waste bandwidth with an introduction. We welcome lurkers. If you have a question, ask it.

New member JohnnyB speaking who's been occasionally consulting this site for a few years as a non-member and has finally decided to join in the fun.

 

Here's a question for guys who turbo their gsxr-1100's. When you fit a 2mm cylinder spacer to reduce the compression ratio, how do you seal the oil-drain tunnels from the cylinder head which will now be 2mm shorter than the new gap they have to fill?

I have NEVER seen theses special larger seals advertised to go with the new spacers. Have you?

 

Sorry have to go now and do chores ordered by my boss, so will chat later.

The seals are O rings in parallel bored holes - they auto adjust for the height difference!

Thanks for that info Gixer1460,  I couldn't work it out from the workshop manual drawings OR oem spares  drawings.
