Standard transfers

[sugarlump]

Should I grind out the 'bulge' in the case transfers, it looks a bit restrictive?

I don't know much about tuning but while I'm in there replacing the bearings & seals this weekend...

Standard et3 barrel going back on (until i can afford a nice kit, crank, carb etc ;D).

Cheers,

Maybe a gain of about 1 HP on a standard, not really worth it, time on the exahust port would be better spent.
