High compression piston:
A friend and I were looking into transplanting a bigger bore piston into the bike. Since this would displace more, it would compress more gasses into the same head volume and the compression would be raised. One possibility is the CRV piston. Apparently this has been done before and it's working fine on another bike, with a bearing on the big end. The deck height of the CRV piston is lower that the standard 500 iron barrel piston, so this transplant involves increasing the stroke by installing a different con-rod. However I'm not convinced we'd be able to get the tolerances at the Gudgeon pin and big end close enough to make this reliable. Anyone out there know a machine shop in Mumbai that can do this properly?

The other (proper) way to do it is to order the high compression kit from abroad - piston, cams, big end bearing, etc. This will cost around $900, to start with. See costs here. I'm not sure all that expenditure is worth it for this bike, especially given what the end gains will be - I mean the Enfield is never gonna be a Ducati
To cut a long story short, we're still looking into it. Any ideas to avoid silly expenditure are welcome.

Exhaust
Putting on a free flow exhaust by itself will probably not do that much good. To get the full effect of this you have to also add a free flow air filter and re-jet your carb. Some may even choose add a bigger carb and 'port' the inlet and exhaust ports since the standard cast iron parts can be a bit rough. My bike has a 30mm flatslide carb. With all these mods there is a decent increase in torque. The glass wool is for sound damping since the other exhaust I had was way too loud.

Hard to get all those things in the same place. There's an area in Bombay called Lamington road where all this is available albeit in different little shops. Alternatively in Delhi's Carol Bagh market. There are some online stores like this one - I've bought something from Ashish at Royal Motors before and he shipped it to Bombay, but his payment gateway wasn't very reliable, so I'd deal with him on the phone.

Doubt it. The barrel and bore size if totally different.

The sound is far more decent than my last one - which didn't have glass wool. It was so loud that it started to seriously irritate me while riding. This one is also a 'straight-through' muffler, so the bike revs more freely through the range. The perforations in the tube and the glass wool really helps to dampen sound. If you're in Bombay, Anthony in Bandra can get one for you.

500modder, is your bike back to stock?

Hog_Head, its difficult to get these parts off the shelf in Bombay. Definitely you'll get some of them. I'd suggest you try making them at a fabricator. If not, try to keep it minimalistic.

There are two types. One is a smaller one (used on my bike), while the other one is slightly larger. I'll check for both when I do get time. The smaller one is difficult to source.

Hi Gordon. The bike currently has a custom rear-subframe, custom front and rear mudguards, custom tool box, rear-sets, cafe tank, clubman bars, top yoke, Smith meter, cafe seat, 30mm flatslide carb, oil cooler and free-flow exhaust.

As soon as the riding season is over I'll put an alpha bearing on the big end. Also considering the following - high-compression piston, alloy barrel, stroking the engine. Alloy rims would be great too, but I haven't seen 19 inch ones.

Do you have a contact number, or better yet email address for Anthony's garage?

Gordon - do I recall that you were designing and making rear sets?
