On the right is my high rev modified piston
As you can see the piston has been ramped and trimmed on the intake side of the skirt this has allowed me to reach 18000+ rpm I have also ported the cylinder in a totally weird way I raised the transfer port by 1cm and extended it towards the intake because there was still enough space for good compression in the cylinder as I was experimenting i also added a small boost port keep in mind the other transfer port remained untouched as I didnt know if I was destroying my engine or not when I did this I noticed a huge increase in torque and rpms and also a different engine tone I was also able to tune the engine leaner than usual heres a look inside the cylinder like I said all I did was experiment and I got huge gains from it I decided to tear the engine down because I will be putting a new piston ring in I have also got a new pullstart coming because I want to do a neater job on the venting as bad as it looks its smoother and polished over and runs great
