Aaron,
There are only two covers that I've noticed. Vert style and sloper 160/175 style. I think the CL175 sloper covers might have a larger breather pipe attached but all the sloper covers are interchangable as far as bolt patterns go.
I'll take a look at all mine...the CL sloper may be a bit more heavy duty....the engine case rear mounts changed from the 160 to the 175 sloper so maybe they beefed up the cover too.

Oil covers are apparently different from vert to sloper. These pictures don't show as much as I'd like the triangular hole patern difference, but you still might see it.

Wow, looks like the oil holes may be offset about the same amount as the change in incline of cylinders between the vert and sloper. That's a new on one me. It's just dumb luck that I've kept the oil covers with the side cover they came on when I've built engines.

That top cover came off a 68-69 CA175 with a pressed steel frame.

Do you need regular sloper cover...I probably have one lying around.

Yeah... I never noticed until recently. I welded up the crack in my oil cover but could user another head cover if you've got one.

I have another oil cover . . It might match, I'll check the photos. And I guess I owe you for the Number plates!! How did you bust the valve cover?

How about making a set of brackets to bolt it up using the cover I sent? Something really trick and alloy . . . heh heh

Scott,
I cracked it on one of my get offs that Joe doesn't think that I ever have. I didn't realize it was cracked until (obviously leaked oil) I looked at it from the back. It was good practice welding aluminum. I can weld aluminum ok, but need to work on it. I didn't realize that there were to different types of oil filter inspection covers so I figured with all the covers I thought there, now there are only half as many.

Making brackets to mount it wouldn't be to much an issue, mounting it so the oil holes that feed it would require some brains.

Aaron,
You cracked the head cover in a get off??
Wow...that had to be a pretty hard hit, hope you checked the forks and frame. Something had to move quite a bit to crack that head cover.
They leak pretty easy though...after I got Hiroshi's bike running Mary noticed an oil leak on the head cover. We screwed around with it and found two tiny pieces of old gasket stuck to the cover and that was enough to make it leak. Surprised me...I figured with eight head bolts holding it down, and being up high like that it would never leak.
You've got one on the way on Tues. I found three of them in my spares.

Oops, I fucked the breather baffle up on the head cover by tampering, and the oil filter inspection cover from the get off. Just to clear that up.

Thankso Branso

PVL packed and leaves tomorrow UPS. The extra stator is not a spare, can you fix it for me? I forgot to send the receipt for your records in the package so I will send it tomorrow seperately.

I spent a few hours talking shop with John Heeley tonight. After discussing static timing vs dynmic timing I'm glad I switched to VP U4 gas and I would like to statr on adjustable cam chain timing. Can you whip somethin up for before the next event?

Aaron,
By STATOR...I hope you mean ROTOR...? Cause I don't do anything to stators...but I do change the taper on the rotors.

How to you like the VP U4? I've wanted to try it, I think it's probably the best fuel for our bikes. Where are you getting it? Bring enough for me the next race :)

I didn't get a chance to check the cam timing on that new megacycle cam you sent...I have a feeling their new machine is a lot better than the old one and the cam is probably very close.

At some point I'll come up with something for cam timing. I've seen several methods....seems to be the easiest might be to use a reground CB200 cam with a modified CB175 sprocket on it...that way the cam is already set up with the flange and bolt holes, you just have to bore out the center of a 175 sprocket and cut some slots. Of course it means buying a new cam. Might be possible to sell good used cams to other 175 racers. I'll have to take a close look at the CB200 cam compared to the CB175.

I'm guessing a couple or three degrees of cam advance might get us a little bit more power...but we'll have to re-clay the pistons again too.

Just looked at the VP U4...only 92 octane....might not be the best for high dome old engines like ours....I'd feel better with something like 96 octane.

Have you melted anything with the U4 yet?

Yes I meant rotor. I come with my own decoder ring. What is the dynamic compression ratio that would put us in the 96 octane catagory? 8.4:1? I jus learned how to do it, and I came up with what I thought was 8.0:1.
