I'd be more worried about the front brake torque stays being in compression......................

I really wish you guys would just stop this..... There is a wideline FB frame and a very sad looking set of bare cases sitting in my garage and the last thing I need right now is for you to get me in any deeper with the war department.

David, when I used the Gold Star springs on the racer, I gave up trying to sort the retainers and odd large collets, we ended up using retainers and collets off a Toyota Corolla which worked out very well. I did machine inside the top surface of the valve caps for more clearance, but none have hit so far, and this without any extra packing other than the stock ET 160 inspection cap gaskets.

Francis Barnett?

I noticed on the ex-Colin Wills bike above that it has a Terry Prince top end. I also see aluminum rocker cap spacers. I had to use similar ones on the racer because the Gold Star Valve springs needed a bit more clearance under the cap.

David, the said spacers looks like Neal Videan gaskets...

Well, that makes sense. I looked at mine again and they are a bit wider than stock. I am used to seeing the red gaskets that I have been using for years.

The cap on the right was just to close to the retainer and valve stem. I took a cap with a hole in it and cut out a larger hole. I then welded a piece of aluminum on top. All I needed was the thickness of the top of the cap to get clearance, and only on the exhaust. I ran the aluminum spacers on the rockers also just to be sure there was no touching of the adjuster.

Thanks, Eric.

I assume there is a side stand or center stand calamity.

That Looks like Mark Warriner, with his Manx Based Norvin.

Higher valve caps, I am not sure where they came from most probably Terry Prince.

 

[davidd]

Terry did make some taller caps, but he warned me once not to use them. He said that they were not machined properly and there is a thin spot on the inside that will let go.

Thanks David I will check for thickness but they have been fine up to now.
