If you have, in fact, been lurking here as well as other chainsaw/forestry sites, you would recognize the screen names of the people in this thread that are actually ATTEMPTING to help you. Do yourself a favor; curb your childish *s-worddick attitude, shut your fuukking mouth and open your eyes. There are so many “bread crumbs” laid out for you to get you going in the right direction, Hansel and Gretel would be morbidly obese . You’ve already answered your own question MULTIPLE times in your own responses. Stop trying to be an internet tough guy. No one cares about feelings here, let alone ego.
No one knows everything. We ALL learn from each other. In the world of “built” 2 stroke engines a BGD, mild porting, muff mod and timing bump ARE mild mods. Once you cut the top of the cylinder off and make a 2 piece head, build a stroker crankcase, design and machine your own piston; then you are into major mods. Of which, several members posting here trying to give you advise have done. Just because YOU haven’t seen it doesn’t mean it didn’t happen.
Grow up and act like an adult or go back to Facebook and trash all of us. I’m sure everyone will support your tantrums and antics there. I personally prefer you stick around, but could give 2 schitts if you don’t.
