Hello Pete,
Your big comet, Have you stroked it ?.
Good Luck Bill.
Has anyone tried a Harley silencer? I don't know anything about them, but I've noticed a few with very small after market silencers that seem to run very quiet (for a lumpy vee twin).

My 2" Supertrapp is the same as another Vincent owner in my hometown used for his Harley Lowrider, only he had two of them.
By the way: my wife is looking here for a mirror, I changed it from left to right when we visited Scotland... She was already confused because whe had a weekend without breakdowns!
Hello howard,
I think you can tune the Supertrapp to make it quiet by taking plates out,
Or putting them in, Is that right Nobby ?.

I saw one in a shop the other day, Trouble is you will loose power ?.
If it was me I would leave the end off, where I live even the cars have
6'' end exhausts, I spoke to the local car MOT man and he says he has to pass them !!.
They are very expensive, But I like Nobby's idea of a 2" pipe + Supertrapp,
I have a 2" front pipe off the Lightning I could use !!.
If I ever get a 600cc built, That is the way I would like to go !.
All the best Bill.
Yes you can tune them with plates for sound but more important for power! Peter Volkers is using a normal Vincent diameter Supertrapp and he won several horsepowers on a Dyno. With the 500 I rode with an open cone (like on the picture in this thread), but later I discovered that with a closed endplate the riding on the 600 was nicer and more smooth through all revs. I am not an expert in this, but maybe the same reason that megaphones are not a good solution for Comets?
Hi Nobby
I don't know the theory, but it was "known from experience" (I don't know who's experience or when) that Vincents didn't run best on megaphones.
