Thanks Matt ,
i am running 2 deg advance with 100LL and 14cc head volume ( if i remember correctly ) .
Each time i have saved up for vhm heads , i get distracted and buy something for my 300 .
My tuner says that i can run a smaller head volume , I will be sending him my spare motor once i have finished cleaning the casing with the soda blaster .
My bike likes to rev to 12500 rpm , didn't try any higher
I think that i will get the rs chassis for this spare motor , but then it never ends
