head work after boring

[Larry's Shee]

you don't bore a 2 stroke for power......you gain almost nothing.  You save the bores for when it needs rebuilds......and it will need rebuilds.  Again.....don't bore for power....there is none...........4strokes make power by boring, not 2 strokes.

 I don't think a 4poke quad would be much different really. A big ole V-8 yeah.

Hell, if the chokers get nearly a 2;1 displacement handicap for Mx, boring one 1mm isn't going to make much difference.

To O P, only bore whats needed to straighten the bore and run them. If it don't make enough power, look into more aggresive porting. Or just sell those jugs now and get some cubs.

 

JMHO, your results may, and will vary.

My apologies ivshould have said I have to bore the jugs from an old meltdown
