yes, where reed block goes and throughout all the transfers and ports.
I've never used Mitaka...but someone else on here might have some input about them.

I guess a dremel is my friend in this case  :wink:
Yeah heard bad things regarding miaka so i will go wossner i think , also crank needs
A rebuild but i may get a whole new wiseco or wossner crank as here in uk a full bottom end kit is £210 but to have mine rebuilt with a wossner or wiseco con rod is about £165.00 plus my crank has seen better days to be honest

sandblaster:
Go Wossner on the rod and the piston.... You won't be sorry...

What are the wossner full cranks like? Are they balanced properly

sandblaster:
You buy a rod kit and have your crank rebuilt with it.
You can send your crank to a rebuilder and have it balanced.
