Hi,

A few years ago I asked a motorcycle engineer if he could adapt an early Tenere petrol tank to fit on a 1991 XT600E
I took both the bike and the tank to him and his verdict was that anything is possible with enough time / money but it would require quite a lot of work including cutting and welding the tank, and then sealing it in case there were any tiny holes through the weld. Also the huge looking tank has a large hollow for the air box, but the 600E has the air box elsewhere.

It worked out cheaper and easier for me to buy a new Archebis plastic petrol tank, and this had the advantage that it funnels cool air to the top of the engine (more than the 600E tank) and made reaching the oil filler cap / dip stick easier than with the original tank - no need to remove a screw to take off a panel. A tank from a Tenere, which does not use the frame as the oil tank, might block access to the dip stick completly!

We had no issues with the bikes overheating when fully loaded on the dirt in the Australian outback, and it was over 40 degrees for a good part of the day. Don't know if it helped or was needed, but the 600E han an oil cooler added to it. It also had a compressor for air horns mounted on the head steady bracket which couldn't have helped engine cooling, but the onl thing to overheat was us!

Hope this helps

Mark
