I gotta agree with Groove here Crassius. You've judged this forum after being a member for only a couple months. You are obviously a builder but don't say how long YOU have been doing this. You buy the engines for your builds from BGF and are having problems with them, (really?) On one of your post you recommend "blowing" through the exhaust to see if it's plugged. With what, yer lips wrapped around it? There's NO WAY to build enough pressure with your lungs to make this a valid test. So it seems you still have some things to learn also. Not knocking you cause we all keep learning, He!!, I wish I knew EVERYTHING, But I'm not even close.
And yes, there are a few here that don't have the experience you obviously have, But this is an OPEN forum, and we were all noob's at one time or another, even you. The first thing you have to do to learn, is ask the question. So we all just do what we can, even to go as far as to describe which end of the screwdriver to hold if need be.
But I do have to agree with you on one thing. People that churn out bikes to sell after building only one for themselves are just looking to get someone killed. So far I've got somewhere around 70 builds behind me, and was building bikes for me and my friends for a few years before I started doing it as a small business.
So take it easy on the button pushing generation. They really didn't have a choice as to what era they grew up in. As long as they are willing to try, and learn something in the process, it's all good in my book.
fatdaddy.
P.S. And Google is a GREAT place to get answers, It's how I found this forum.
