No, you wrong, it is totaly legal! read the roar ruls!
There is nothing about timing!!!!!!!!!!!
Just to give you an idea how it can be done one of the way. If you make conrod lenght not 25 mm, make 17 mm you timing will be 164 degree. It is just one of the way to do higher timing on exhaust and styas within ruls. Marine mentality!!!!!!!!!!
Just don't look on issue ordinary, be creative!!!!!!!!!!!
I have offered my help, but was regreted. I can be very helpfull with my marine mentality. I want to be very helpfull for everybody! I want to share my ideas and expirience!
