you need to match the porting on the cases so to say, everything is sucked into the crank case, it must be opened up as well, make sure you splitt the case so debri does not get in there when porting. I would put a320 main in the stockers, yours has about what mine has, I even drilled my 320 jetts out, it made a diffrence.

Two things, you do NOT need to match the cases. it will give you a very, very slight gain if anything, and....it'll lessen your gasket sealing surface.

 

If the motor is all apart...go ahead, place the base gasket on the cases, use a marker and shave the area not covered by the gaskets. However, are you prepared to split the cases and completely dissasemble the motor to get 1-2 HP tops....? Not worth it in itself, IMO.

 

Second, why would you "drill" a 320 main? Mikuni carries jets over 400 series....unless you're running alcohol....

 

It made a difference because you probably needed a 330 or 340 main....which, is available all day long....????
