I'll take the good cyl sleeve and the brake caliper if you can confirm that it's usable. I don't mind having to clean it. Thanks

thanks leo

Thank god NZ is behind Oz :wink2: and we don't have such a rule here :D

Could anyone tell me what this engine number stands for ? The head and the jugs have matching numbers at the front, but this one is stamped at the back.

PM sent, thanks.

Thanks for the replies. I did this mod on my GS850 (the same BS carbs as on the XS) - the drill size 7/64 is a part of the Dynojet tuning kit - and the mod DID make a difference - it helps the jet needle lift faster. Granted though, that's a 4 cyl engine with a 4-1 exhaust.

Yup, that's the one. What size drill is that, you know?

What is the drill size for drilling out the vacuum hole in the BS34 slides (that comes in the kit for when using pods and free flow exhaust? Such as: Heiden Dyno Jet Kit (Click here) I have the other components for jetting but wasn't able to find this info after searching the forums...

PM sent, thanks.

So, no way to tell the year of the engine?

yes I realize that - and it's only stamped with the number "447"

Thanks for this thread. I was able to identify my newly acquired XS as a 1980 Jap model SG(frame # 3G5 000xxx) But my engine is only stamped as "447". Is that (un)usual?
