Any reason I shouldn't widen the LT80 exhaust port 3mm on each side and also raise it 3mm? I don't have any porting experiance but seems I could handle that.

I'm sure the shops who work with these minis would produce better results but I just need a little extra juice.

Shouldn't the exhaust port modification along with the clutch mods and removing the head gasket wake it up a little?

thanks in advance for any comments.
