500cc web site link

I expect most people have found the above web site, but just in case others have missed it ...

"The Vincent Comet Pages ( DRAFT) - It is the intent of these Vincent Comet pages to strip away any non-essential Vincent Twin info and focus only on the post-war Comet 500cc single. This is an effort to help the Comet owners repair and ride their Comets. I need all the help I can get, especially pictures and graphics having to do with Comet technical topics. '

PS I think Meteor Owners might be allowed to view it too ...

The head bracket on the MO30a needs to be redrawn, it`s the wrong way round.

There is worse than that!

Below the actual drawing MO30a is an added photo of F47 Engine Mounting Bolt and nuts, together with the following text:
QUOTE
" This shoulder nut ET154 is short for early Vincents RC/1306 and before and actually should not be found in use on a Comet as Comet chassis numbers begin after 1306.
Reference to the Spare Parts List shows that spigot nut ET154 and engine mount bolt F47/3 are used on all frames prior to RC/1306.
All subsequent frames (to include all Comets) use ET154/1 and F47/4.
In this picture you can see that the shank on the special nut is longer on the later variant ET154/1.
Also the threads on F47/4 are longer than the earlier version."

This is mainly wrong - for the correct info see KTB by EMGS.
It is important for safety reasons to get this right.

It is just wrong to state
"This shoulder nut ET154 is short for early Vincents RC/1306 and before and actually should not be found in use on a Comet as Comet chassis numbers begin after 1306."

The Blue Harpers Spares list does state 'ET154/1 [ the long nut ] Used on engine No.RC/1306" but RC prefix numbers are FRAME NUMBERS!

P.Richardson 2nd ed 1960 page 219 gives Frame No. 8614 as the introduction of "Modified head-lug and cylinder head bracket FT 3/2", which is the 1951 type 3 lug.



May I suggest that the web site be amended to be consistent with KTB?

I am beginning to regret my original submission.
It does state "DRAFT" on the web page
http://www.thevincent.com/comet-pages.html
but maybe the "R" should be deleted?

As far as I can see if a drawing hasn't been through the drawing committee its not necessarily correct nor are any parts made from it.....

"whats the drawing committee?" -go to the back of the class

Singles or twins, owners should get away from the idea of referring to frame #s when deciding on ET154 or ET154/1. If the headstock fits on the outside of the head bracket use ET154.

If it goes inside a slot in the bracket, then ET154/1 MUST be fitted.
