I put a Goldstar on my 07' and it is absolutely great..  Sounds super...The Ace Coffee can is also very nice.. A good combo...

I have the Goldstar exhaust system on my bike, and I like it very much.
I can't think of anything I'd rather have on there. It looks great, and works great.
I love it.

Ditto Garbone and Ace on that.  I'm a Goldstar man.  It was the first thing I did a few years ago. Very good quality and it fit up real good too.

My 2003 UK-spec Sixty-5 came with a muffler that is much shorter than the classic “bazooka”, but not as short as the free-flow varieties that are on the market (see picture). It is quite light in weight. Would I be right in assuming that it would be someway in-between the two in terms of performance? I plan to fit a conical free-flow filter (with a re-jet to suit), but I am reluctant to change to a noisier muffler. By the way, there is no hot-tube in the header pipe. I would welcome any thoughts.

That exhaust and rear hanger look very much like the Brituro kit fitted to my UK bike. It gives way more power than the standard "bazooka" and is plenty loud enough. I made a tail pipe baffle for mine out of rolled perforated steel sheet, which tones it down slightly and improves  torque at low revs.

Chrome is good quality too.

I checked out the the thread on successful jetting for free breathing engines but didn't find anything for a 350 with a 24mm Mikcarb. What jet sizes would be good for such a Bullet with a K&N air filter (Model R-1060) and the stock short bottle silencer with a small hole melted in both baffles? And, what about with a straight-through 'silencer'? I won't have the latter because in Delhi, one really needs low end torque often.

DarthSid,

You need to try out different jets before you get the set up right. Here, people mod their 500s and not many 350s. For your 350 with a K&N pod, start off with a 100 main to maybe upto 115 or 125. Pilots can go upto two sizes bigger than stock. Plug chops will help you dial in the exact jet combination.

Cheers,

Jay

The muffler I describe in my previous post seems to have been a standard fitment on UK Sixty-5 models - as in this road test feature:-

http://www.realclassic.co.uk/enfield030320.html

As you say Chasfield, it gives a pleasant bark, and is not too loud, so I am reluctant to change it - especially if it's a decent performer.

I used to run mine with a 100 main and a richer slide and raised the needle up by one notch, that was to suit a straight through silencer and a K&N pod filter.
 Although some people I know have got away with just a 95 main jet and the standard slide if using an unmodified sixty5 exhaust .
The pilot jets rarely seem to get changed for just different filter and exhaust changes, although the vm24's are a bit more sensitive to change than the 28's.
Never underestimate the value of improved combustion efficiency and reducing parasitic engine and rolling chassis losses.

Jay, I am aware that 350 owners and modders are a minority here (even you have an AVL500, right?) but still posted my query in the hope that someone may have successfully hit the spot with a free flowing VM24/350 configuration. I know I'll have to be good friends with my rusty old plug spanner to get it right but was hoping to shorten the exercise with some inputs from the experts/people who've done this. I'll start with ric450classic's and your inputs. How come nobody talks much about the pilot jet with the VM24? Most people focus on the mains which would explain the dearth of pilots for the 24.

ric450classic, interesting you mention that the pilot jet rarely gets changed in the VM24. Why is that? And, is the VM24 more sensitive to change because of the considerably narrower throat (vis-a-vis the VM28) and, therefore, a smaller amount of air to work with? A small amount of increase in fuel in the VM24 would probably not be perceptible with the VM28. Is that right? Or, are you talking about changes in the airflow?
