P200 Malossi 210

	The P210 Malossi cylinders tend to get damaged on the softer exhaust stubs because of the way the exhaust system is attached. This problem is especially bad with rubber mounted expansion chambers. MB Developments can machine and reweld a new stub to repair an expensive cylinder that might otherwise be scrap.

	The transfers on the casings need matching to those on the Malossi barrel.
	Malossi 210 exhaust ports need lowering to match the piston at Bottom Dead centre. This is all that really needs doing to the barrel to tune it. Raising the exhaust port usually kills the engine and means it won't really pull 4th gear.

	Malossi 210 cylinders need matching a little to suit the transfer feeds on the casings.
	This is because the castings used to make the 125 and 200 engine cases are dual purpose. They are machined to accept 125,150 or 200 barrels. This means there are some funny casing transfers which don't match the barrels.
	No it's not a tunnel, this is a malossi exhaust port which has been lowered and then flowed.
