Hi friends!

The "old" Classic Bullet 500 (mine is from 2001 and an export model) has a Carburettor flange assembly of aluminium (Nr 144083) fitted to the cylinder and the carburettor is then fitted to this assembly by a carburettor hose made of rubber (Nr 143143).

I have now seen that an Indian company sells a combined Carburettor flange assembly all made of rubber. It seems to be reinforce by metal inside the rubber part that is mounted to the cylinder.

One can find the item here for example

Has anyone tested it?

Persistenc?

For me it seems to "kill two birds with one stone".

That Mr H doesn´t sells it makes me a little doubtful about its function / quality.

Am I wrong?

My opinion is not to waste your money on such rubbish, but to use the Amal connector part number AM/2622/123 from Mr H. Don't be put off by being Amal, it fits the Mikcarb perfectly and won't perish as quickly as the original.

What you are looking at from New Delhi you will find here http://www.hitchcocksmotorcycles.com/pa ... nd_Rockers and supplied by the kind folks who provide this fine forum

The one-piece connector on eBay is a cheapo copy of the original Mikuni item, which as Beezabryan points out, is available from Mr. H (under part no. 142681C). However, this will NOT fit your Bullet; I suspect this also applies to the eBay item. Follow Midge's advice and stick with the original set-up.

the mukuni agent in queensland sells similar but they are genuine mikuni parts got one on one of my heads been there for a few years now does not perish like indian rubber.corts a bit more but you get what you pay for.

Can anyone tell me why the Mikuni manifold part nr 142681C from Mr H won´t fit my 500 Bullet from 2001. The aluminium made Carburettor Flange part nr 144083 that came 1997 or 1998 was as far as I know a change caused by the PAV-system (with a metallpipe that came out from the bottom of the metal Carburettor Flange).


If one has deleted the PAV-system I can´t see why the Mikuni manifold part nr 142681C would not fit. Did they changed the carburettor 1997, or what?


Yesterday I mounted the Indian made rubber manifold I bought from Ebay India, and I works perfect. I kept the two existing standard gaskets between the cylinder and the rubber manifold. So why would the better quality Mikuni manifold part 142681VC NOT fit, and moreover stand even better and longer?


With the carburettor a bit closer to the engine there is more room for opening and adjusting the carburettor. And lesser with parts.

Well, the Mikuni connector from Mr. H wouldn't fit my 2002 ES Bullet because it was fouled by the steady bracket lug on the cyl. head such that the bolt holes wouldn't align - and I didn't fancy grinding away either the lug or the flange. Maybe your bike is different. But Mr. H's listing for this part states it's suitable for pre '96 only - why not ask him ?

My bike began life as a 1999 home market model, although its history is somewhat obscure and in the past it has been substantially updated. It does though have an all rubber manifold which works just fine and is easy to get a good joint seal with - as long as it is not over tightened! So not too much pressure with the spanners please....
One of the exciting(?) things about our Enfields is that they all seem to be different. So, particularly on carb/intake/exhaust matters no one can be too pedantic in their advice. My bike has wonderful things like an extra air adjustment screw on the intake manifold spacer so that adjustments can be made for high altitudes, I think. Great for the Himalayas - of less use in the English Midlands!

Hi WINKIE--------- Glad to share your enthusiasm for this "wonderful" marque BUT (there's always one, eh ??)I'm sorry to "pop your balloon".. That screw is probably a blanking one from the removal of a PAV system ---- it was a vacuum signal line to the main valve unit...If I were you I'd remove it--put a good dollop of your favourite gasket sealant on it --and replace.. It's a potential source for a "mystery" air leak and consequently weak / overhated running..... The air in the mountains gets THINNER as you go higher so if anything you could use that screw for an oxygen boost valve 9 Bloomin expensive though )...It'd save on having to re-jet to a larger size...Some bikes/cars have an automatic compensating fuel/air mixture system.
