I was on that rally Paul, I was using an SFC 1000 that was the property of the Norwegian Per erik Ramstaad, for whome I had bought and paid for the bike on his behalf, he was happy for me to use the bike for that weekend (Andrea was pillion) If I remember correctly the organiser was Claude who lived in Paris at the time? I never saw the oil temp gauge move off the bottom stop by more than a few millimetres, but that day, it was showing "normal" a small oil leak from the head gasket was suddenly no longer showing as oil but as cooked crust.

What year???????

It was Jean-Claude Clem who organised.
I'd need to dig out the T shirt for the year. I think it was 2001.

Just wondering what a blisteringly hot day in UK would be like. Probably mildly warm by Australian standards  :D

My Kawasaki Z1300 is gets uncomfortable under such conditions. The liquid cooling and electric radiator fan keeps the engine temp within limits, but that bloody great lump of hot metal sitting down there between your knees throws a lot of heat up at the rider, especially when stopped at traffic lights. It's like sitting on top of a volcano. If you only have a bit of fuel in the tank (eg. running on reserve) on a stinking hot day with the sun shining on the black tank, it's not unknown for the fuel to boil. A common modification for owners in hot climates is to glue a layer of that reflective foil insulation stuff (like builders use) on the underside of the tank to reduce the heat transfer from engine to fuel.
 
There are specific products made to glue to Plastic side covers on dirtbike to stop them melting from the exhaust. Exhaust wrap also helps, but only behind side covers, stupid ugly stuff. My 2 worst heat-related rides were qued up to get into some big race meet at Oran Park front entrance. It was uphill and took an hour to get 400m in well over 40c heat. It got ugly real quick on overheated engines and rider. The second was a ride organised by one of the local Cafe Racer clubs when it was suddenly trendy. There was anywhere from 500 to a 1000 bikes meeting at a Cafe at Tempy and heading down to Woollengong also in well over 40c heat. The problem was it happened on the same day as the 10,000 pushbike ride to the same place, TRAFFIC MAYHEM was the result. Chock a block slow traffic for the whole day also coming home. Motobikes stopped all over the place from the heat, a nightmare. That qurdered me of ever attending anything similar ever again.
 
I think there will be a few takers for this. Awesome achievement. Was there a need for it? Not really, which makes it an even bigger achievement. If i had the money i?d Be right up for this.

too many engine experts in this thread, and in truth, there is only one who knows what he is doing and talking about.
What is the latest state of play with the four valver, how many sold, any reliability problems etc

Thread locked to avoid confusion with more recent thread on the same original topic. A perfect example of the confusion caused by (1) posting to an old thread and (2) going way off topic
