Hi All

I'm converting to 535cc and upping the compression as part of the rebirth of my 500 Bullet Clubman S.

What's the concensus on fitting a decompressor or not?

I never used te decompressor when the bike was std comp 500 and I've always blanked off on std engined 350's I've owned.

Tomshayes. I too had a Indian 500 and I didn't alaways use the decomp because, at ~6:1, it wasn't so hard to kick. BUT now, with the 8.5:1 535 piston, the pain of getting it wrong means I always use the decomp. Mine's mounted in between the rocker boxes because I have a second plug in the original decomp hole.
Cheers, ChrisD

Thanks Chris... Think I'll keep the decompand see how it goes..

Hi Tom



You might like to speak to the Bullet Whisperer (Paul Henshaw at Performance Classics).



My 612 has a compression ratio of around 9.5:1 and Paul has a neat solution.

Picture here:






The idea (and it works) is that you use the little lever thing to reduce the compression, for starting, and then flip it off once the bike is running.



The pictured version was Paul's prototype (which is fitted to my bike) but I believe Paul has since designed a Carlos Fangango version.

Fandango.

There are a few of my modified decompressors out there now, but here is that first one in action, as fitted to Count Johnny's machine just over two years ago ... https://youtu.be/KXg6uZkdJ3k

Here is a Royal Enfield Fury 500 also equipped with a modified decompressor, I offered this idea to our hosts a while ago, in case anyone thinks I am trying to muscle in with this [they are fiddly to make one at a time] ... https://youtu.be/yiYNNJ8soAE

Carlos Fandango ??--------- Well, well, there's a "Blast-from-the-Past" and no mistake !!------ Personally I gave up smoking but opted for the Chest Wig..... 'er indoors so was much impressed at the time that she dumped me !!..For those who haven't a clue what we're on about, here's a taster of life in the fast lane ( sort of !!)..
