I've looked everywhere (virtually) here and on the web for a vendor for a cylinder sleeve for a 78 GS1000. The closest I came was Wiseco.com that had a listing but said they are no longer available. Can someone refer me to a supplier? Many thanks!
 
I'm not aware of anyone making stock sleeves for a GS engine. If anyone would know what is available I think it would be APE. You might want to contact them and see what they have to say.

EDIT: Guess I'm wrong on this one.:)

Great, thank you. Found them there; no prices, though. Will email them.
 
And in a hijack....

Speaking of cylinder sleeves....

I got the cylinder block off today (factory fresh, never been off) and got my first good look at them, no scoring really. My question is about measurements. With my calipers I can only check about half an inch down into the cylinder. Do I need to buy a special caliper to take the factory recommended 6 or 8 measurements? Also, they all read at between 69.6 and 69.75. The manual says standard is 70 and 70.1 is oversize. It's a 30k mile motor. Does it seem reasonable they'd still be at below 70 or must I be measuring wrong?

Hey Doc,

You can't measure a cylinder with calipers, you need an inside micrometer or a bore-dial gauge. You might be able to get away with a telescoping gauge with a regular micrometer but at any rate, calipers are no good since they don't have enough resolution.

That's the answer I needed. Thanks Ed. In the words of Ray (I think)... mo money... mo money... mo money....

I was probably going to let a shop do the hone (probably as cheap as buying a flex hone and they know what they're doing). I guess I'll let them measure for me as well.

You need a DIAL BORE GAUGE to do it CORRECTLY! Nothing else will give you an ACCURATE measurement! Ray.

Gonna see if the auto parts store loans them, if not gonna let the machine shop measure before they hone.

Have them measure AFTER the hone too. If your sleaves are boarderline between a 0/+1/+2 for your rings, it would help to know what the final measurement is, so you're not putting rings a size too small in there.
