thanks for the reply I have done a little to my 350 polished the ports, blanked off decompressor , gold star pipe & silencer, K/N air filter bigger jets, and Mr H's alloy rockers. I was considering slightly higher comp piston.
does anyone do an oil cooler kit, gets a bit warm here in the summer, or do you have to make your own. Most grateful for any advice

Even in Corfu I don't think you need an oilcooler. If you take the actual temperature of the oil in the tank after a run I think you'll be surprised. It's a pretty cool running motor. Over here in cold miserable UK we sometimes have a problem of too low oil temperature.
Have done whet you have to the 350 I would think the next thing would be a slightly larger carb as that's likely to be the bottleneck now.

I’m a bit puzzled by the idea of UK winter weather giving a problem of too low oil temperatures. Even a 20W – 50 oil will work fine down to around minus 12 degrees C.

Presto, it's common for the temperature of even air cooled engines (all engines are ultimately air cooled but you know what I mean!) to struggle to get hot enough all over even in winter in order to drive off water condensation completely. Enfields of all types (singles and twins,) can suffer from incomplete oil circulation even though the main areas (head, barrel, timing chest,) are getting up to working temperature quite quickly. There is a discussion on just this subject going on on the Interceptor site right now where someone is running a modification which moves the return oil pipe to the back of the oil tank rather than sitting over the pick up as it does as standard.

I found that I had cooling issues with my 350. Particularly once I'd improved the breathing so that it would maintain 65 mph plus on the open road. I found that the aluminium barrel was the answer and at a very reasonable cost. As I have the facility to do a certain amount of machining work I went for the off the shelf cheaper version however if you don't have that facility I'd go for the Hitchcocks checked version.

Oh and I do recommend the 8:1 piston.

I agree Mark. Condensation is a big problem with Enfields in the cold. However a couple of points: a) that is not an oil problem, as if the oil can't cope with the temperature; b) condensation ought not to be a problem in the sense that the oil will hold the water in suspension (the 'cream' we see is a sign of that), it's 'standing' water that causes trouble, not this 'cream' (which some oils produce more of than others).
