Many engines have the water inlet directly under the Ex port duct.
Jan tried the idea of stopping flow directly cooling the duct bottom, by filling it with epoxy,and the engine lost power and detoed badly.
Franco at TM has decided to not use at all the holes in the case and cylinder that would allow ALL of the flow into the cylinder to enter under the duct.
I cant believe that he did not test this back to back against the original method of supplying water from the case via a hose that enters up high above the Ex port.
I am about to do this test, along with ceramic coating the duct,as there is still a belief by some that a hot duct will help the pipe work better.
This is very wrong in my opinion,as overheating the duct will overheat the plugging mixture pushed back past the rising piston, but the only way is to test this back to back.
My other test will be to do the cooling "properly ",that is to have the cold water enter the cylinder at the back ( opposite the Exhaust ) then flow over the transfers,cooling the Ex last.
In the TM homologation papers there is no hose shown, so having one around the back is not going to be illegal.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
