Photo might help.  My 250 pipe goes under tank with no issues

Montesa worked hard to provide an unobtrusive routing. I don't see how you could route it elsewhere without it being both in the way and liable to damage.

 I had a 200 for 18 years building a pipe never crossed my mind. If I remember right the underside of the tank had a protective layer protecting it.

My 348 has a similar thing going on. I think the factory fitted something to the tank that was glued on. it must have fallen off in the 80s.

A previous owner bolted a bit of bent and hammered steel sheet to the frame that acted as a heat deflector. it didnt look very neat but seems to have worked.

sorry no photos as the bike is in bits at the moment.

It might not be the right pipe or it might be a bit bent or the tank might be out of position or it might be the wrong tank

Does the rest of the bike bike look like this?
