Have a look at page 2 of this thread from Chuck78.
Slightly different cam specs but i think i see .006-.008.
I hope i am reading that correctly.

Anyone have any advice on valve clearances for this engine with yoshi cams? Intake 0.375" lift and Ex 0.350", I also have stiffer valve spring, heavy duty retainers and keepers. I know stock is 0.03-0.08mm, although that seems awefully tight.

Camera doesn't do the paint justice, really happy with how it turned out

Big things happening today, got the engine in the frame! Also got the new tires mounted up and the forks rebuilt and painted. If all goes as planned I should have a rolling chassis come the end of the weekend!

Got the engine assembled! Still need to degree the cams but I should have it in the frame very soon, going to begin tackling the front forks tomorrow.

The project has moved from the garage to the rec room? Excellent!
Were you at the swap meet in Paris on the weekend?
I saw a pair of S&W just like that.

Haha it's scattered throughout the entire house, I'm lucky to have understanding parents.

I wasn't, but they very well could be the same pair!

Couldn't help myself.

Got the frame primed and painted today, also did some very minor frame bracing while I had the chance.
Yoshi exhaust has also been primed using VHT header paint, I'm going to let it cure before I apply the base coat.
Also stripped the head down to lap the valve and change the valve seals, discovered that the head has also been milled down 20 thou.

Next on the to do list while parts dry: Rebuild front forks and begin assembling the engine.

Got the majority of the bike striped down today, all that remains is the front end and electrical.

Next up is prepping the "new" frame for paint, I'm going to bring it work this week to sandblast along with some other parts.

Yes I'm definitely keeping the stock parts, the photo makes the bike look alot better than it really is. I'm all for preserving these old GS' but I do like to make them my own as well.

Haha yeah an hour or my life I'll never get back.

And about the pipe, I agree.
