Velocette Venom, slipping clutch or camming drive? Gas cap repair.

For the past few weeks I've moved to running the Venom Clubman MkII to exercise it and to keep with the vintage british flavor of the season.  Its been running pretty darn good with the exception of a possible slipping clutch and leaky gas cap.  I spoke to Ed G. about this, which he mention that it might not be the clutch but that the primary drive shock absorber was camming over.  The solution is to add a 1/8 inch spacer in effect to keep the cam from ramping over. Since the clutch seemed to be work fine in all other arenas I figured that this was an easy go to give it a try. Here are a few pictures of my go around for making a spacer.

In my selection of bits and bobs within the shop, I found a sizable washer that would only need the i.d. bored out.  After a bit of fiddling with the chinese lathe we had a bored out washer.

Half of the cam ramp drive and spring, the shiny shouldered part is where I'll put the washer. 

Here is a view of the washer on the drive.

The final assembly of drive, washer and spring. 

After removing the belt cover, I pulled out the cotter key and removed the four notched nut on the end of the pulley.  The generator was left as it was adjusted. Only the pulley halves and spring would be removed. 

The washer was added, followed by the spring and then the two pulley halves with the nut. Since I left the generator as was, I installed the belt at the same time of putting on the two pulley halves.  You do have to be mindful that the pulley halves are matched up; that the notch lines up with the slot. otherwise, they will be mismatched and your belt will not be riding in the grove correctly.

I found that the whole pulley/belt/nut assembly could be turned back onto the output shaft by hand.  Then just finish up with the special four pin Velocette nut wrench. 

Don't forget to align the cotter hole with the shaft and re-install a cotter key.

As for the leaking gas cap, I only thought to deal with this just before the ride to the Gathering.  With a section of leather kicking about I just cut a new seal. Easy peasy.

The old rubber seal, cracked and leaky. 

Shaving the edge to fit under the metal retainer washer. 

Not a single leak throughout the ride even with a full tank of fuel on bumpy roads!
