Although they may not deliver 62~63hp like they do on a delimited MC18, they will still push a '16 into the (very) high 50's if carefully set up. Electronics are likely to be the most limiting factor, plus the standard crankcases on the '16 leave a lot to be desired. You can't (easily) fit later cases, but if you buy some and take a look inside you will soon see how to improve the early ones and make up those few extra horses.
I have wondered about the electronics on the '16's before as regard to the tuning of the engines, will the stock ignition be a brick wall above 50hp? Cases I'll be looking at modifying if needed, I do have a set of '18 cases lying around to copy.
Anyone had hassles with the ignition system on an mc16 whilst tuning?
