Perhaps tap it for NPT?

Probably not needed, better safe than sorry.

Oh, good idea. That will definitely work. You could also use a counterbore in a hand drill to square that up some but it may not end up square enough and your method is fool proof.

Thanks for posting this, I am enjoying your work.

I thought this was appropriate…

I hadn’t seen this one before. I wonder if he went through the fine details you’re doing.

Cool, and he probably had more details to worry about than me!

Yeh, that's what I was setting out to do. And I dropped my last 1/8" pipe plug on the floor and it bounced and rolled and lodged itself into a crevice somewhere that I just can't find. So I used what had on hand.

Now where was I? A month ago I put the engine back in the frame, for the last time I hope. I had a few life interruptions the past month but did get my cylinders back on.

After this discussion: http://xlforum.net/forums/showthread.php?t=2080406 I decided to put my cylinder base nuts back in and use the allen nuts that Needspeed turned me on to. Here they are:

Then I clayed the pistons one last time just to be safe since the last few times I did it I had the cams installed one notch off. The clay turned out just fine, still lots of room. After the clay inspections I put the heads back on for what I hoped would be the last time, lined it up with the intake manifold and tightened up the bolts good and solid

Well it turned out I couldn't get the clamps on over the intake manifold. They just would not get past the top cylinder fin. So it was off with the heads again to do a bit of grinding:

A bit of touch up paint, heads back on and now the intake clamps slide on nicely and I'm ready to move on the the next step. That'll probably be the transmission since it is so, so close to being ready.

I think that kind of o-ring is called x-ring. The manifold is normal, it takes a regular o-ring as well. I am just using the x-ring type here.

And yes it’s a Mikuni hsr 42 going on it. I ran it before on the1000cc ironhead. I didn’t know the carb was too big for that bike when I bought it. Even so it ran a LOT better with this mikuni than it did with the old stock carb. Now on this engine it’ll be just about the right size carb.

copy that bill.

Just clicked onto the forum after many years of absence - great to see your shovester evolving you may recall I have a project Shovester went the re phasing of the rockers (EVO rollers) and by shuffling valve stem heights and lash caps got the geometry acceptable bike is at where you are today just about their liken the post got me fired into finishing it Cheers Chris check Rogotek past posts will try and post shots
