I can't remember where this bushing goes. It was with my clutch side hardware. I looked through the HSM diagrams and found nothing.

OK. Thanks for the clarification. I think I'm going to use the .063 copper base gasket to get my pistons at basically zero-deck, then the .042 copper head gasket.

The bore on the stock head gasket is big enough to accommodate the larger pistons? He has .063 and .042 material. Doing copper on the top might help with heat dissipation, but would add $50 cost to the project.

He only has .063 or .080 gasket material in this range. Without base gasket they come above the deck 060. I'll need a copper base gasket and head gasket to get me to a combined gasket thickness of .100 (ideally @ .060 below and .040 above).

GS850 pistons poke out of the bore about .031. For optimal squish I need a copper gasket in the .070-.075 range. I have a message in to Copper Gaskets Unlimited to see what they can do.

Bottom end is good as new (except for the worn crank ball bearings).

Ready to go back together.

Bearings actually seem incredibly hard to find. Maybe I'll just stick with the ones I got.

Outside ball bearings on the crankshaft are rumbly. I need to replace them while I'm in here. Any tips on a good source? The stator side looks like an off the shelf bearing, but the crank output side has the hole in the outer race for the alignment dowel.

The shift drum stopper was kinda grindy, and on inspection I can see it is worn. Should this be replaced?

Bottom half of crankcase is done. Top half is disassembled and washed. Bead blast tomorrow. Then ready to start assembling everything.

Got a set of vintage OEM tank decals from Japan on Ebay.

Finished the starter rebuild.

I did the transfer piece mod last night as well as the mod to radius the filter cap. One other step I added was to expand the first coil of the transfer piece spring so that it would seat tightly on the transfer piece ID. This improves the oil pathway clearance while also ensuring that the...

This seems a little risky and complicated. Is it really necessary if I do the transfer piece mod?

I hope so. Retail was $90 + $90 for custom paint. You can see some bad orange peel in the reflection on the stock picture above. I expect my custom painted "traffic red" to have better attention to detail.

I've read some comments about this here and there. Is there a full step by step somewhere?

Thanks

Where can I get heavier clutch springs? Have no idea on the clearance. The guy has done several 378 conversions, and I sent him the pistons. He said he shipped it back to me today, so I should have it in hand early next week.
