Seals for oil drain tunnels after fitting cylinder spacer

Recommended Posts

Hi to everyone,


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

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.
