I have a friend that has looked into buying a 200 SHO and having it chipped to be a 300. A yamaha mechanic told him that the 200 SHO has a different camshaft and it cannot be converted to a 300. How about it, can you convert a 200 into a 300 with ecu changes only?
Yes sir. Several here have done it
The Yamaha mechanic was wrong. The same cam shaft used in the VF200 is used in the VF250. Only differences between any of the VF220/225/250 sho's is the ECU and engine graphics.
