There was another one by someone else that basically opened up the transfer ports in the bottom of the cylinder (with a half hacksaw) and referred to it as boost porting...and I can't find it.

edit - I know for a fact that I was subscribed to it. I've gone back to the beginning of Jan and can't find it. Lame.

are you referring to the thread that's still missing where the hacksaw was used? I haven't tried it, but I would like to eventually.

Guys- the thread was deleted due to the original poster going ballistic and saying things like "I've seen the questions you idiots ask and this is the best thing you'll ever do to your engine" "I know more than all of you put together" ect.

It was in response partly to me saying "Do this mod at your own risk and be ready to have to buy a new jug if it screws the cylinder up."

Well I had never seen those posts. May have been more appropriate to delete the offending posts and lock the thread, that way it was still there for reference.

Here's the bottom line- If you want to hack up your engine, do so at your own risk, and have fun....these engines are cheap enough, but the advice was not proven to be sound, and there is always a chance that a newb may take it as gospel and ruin an engine.

The reaction of the OP was enough to remove the whole thread.

Sometimes, it's hard to make everyone happy, so the decision is made to do what is best for the "masses."

If someone reacts in such a froward way as the OP did, then we don't need them or their "advice" here....Flame wars, admonitions, ect. are not what we do here.
