I used the tank to ride UK to Nepal, worked perfectly. It was fitted to an oe with totally ttr kit. But will fit the bluey if you buy the kit from totally ttrs.
The tanks taps work fine and has a locking cap, I'll include the original one too if any use.
I found that the original oil cooler fouled the tank so I made a crude bracket to angle it forward, I'll look for that if you need it but if I cant find it you'll have to make it yourself which is easing done.
I sold a spare one before I left for £190 plus postage on Ebay (can be used for xr400s too) so before I put it on there I thought I'd offer it to you guys first.
