I’ve been slowly learning how to do it myself so far so good I’m lucky to have a number of spare heads to practise on lol
I’ve basically cleaned up the intake port
But left them very rough so the fuel can atomize and have gone all out on the exhaust side well best I could get my fingers in ( no pun intended ) lol I noticed a difference straight away when I put it back on my bike so now I’m thinking of upgrading to bigger valves and spring
This is on my stock mod 110 and one of my 140 engines
