RE: BVM 15 speed model
Hallo Rudeboy,
the spinner is selfmade special for this modell.
Also inside the engine the piston, cylinder and the rod is not orginal it is also selfmade and better.
The piston material is from the MB 40 pylon engine from Rob Methkemeijer.
Also the head design is complete different to the orginal. The combustion ration is now 14,5 :1 .
Now is the engine a real monster and can reaf up to 30 000 U/min with no problem.
But still some work to do on the pipe.
Best regards Michael
