Sleeve Length

[Guest]

What is the min sleeve length I can use on my 82 GS1100E? I bought a used 1428 Big Block with MTC flat top pistons off ebay and one of the sleeves is shorter than the rest. Looks like it's been replaced. Can I still use it? 3 of the sleeves are 4.6" long and the one is only 4.38" long.

Case Boring and Base Gaskets

No advice on this one? I'm thinking the .020" difference will be OK as long as the rings are still in the sleeve? I realize there will be less skirt support of the piston, but I am willing to take that risk.

Just need to bore my cases yet and determine base gasket thickness and then I will drop her in. Anyone have any advice on case boring by hand or setting deck height with base gaskets?

Send a PM to rapidray or give him a call. Look up some of his posts, he frequently give his phone number.

I believe the number he gives out is his shop number, but building bikes is his business, so give him a call.

Case Boring

Sounds like a good idea. Thanks Steve.

Has anyone else here though tried boring cases by hand with a die grinder? I thought I read one post here before on a 1327 build who did, but can't find it now?

Give me a call at 714--356-7845. Let me guess, the shorter sleeve is #3? Yes, you can cut the upper case half but you should really have them bored in a mill. That way they will all be the same diameter & depths, and will be bored straight.

Ha, yes it was #3 cylinder that was short! How did you know? Left you a message with my number. Thanks Ray.

Wealth of GS knowledge.

Ray called me back earlier today and schooled me on GS engine builds in about 15 min! He was very helpful and willing to answer all my questions. Thanks again Ray!

Also, the 3rd sleeve is shorter because GS750's had a larger diameter primary gear on the crank!

Glad you brought back the knowledge to share
