Not bashing Source, or anyone else here, but the problem with these "cheap" kits, is that they are marketed as "ready to assemble" and "just as good" as some of the other higher priced kits. This is where I have a problem. The problems that BG is finding are serious issues and if a novice just slaps it together, there will be problems with the motor. Sure, you can take it to a reputable shop and have it checked, but if they fix it, and a good shop will, it will cost you money. Where as, I would just about guarantee, that if you paid a little more and bought a K-1 kit, or something similar, it would be perfect and indeed ready to assemble. So in the long run, which is the better deal? To fix the flange, the taper, the runout, the cosmetics, scrape bearings and rebalance....you are into a good deal of labor on your "cheap" crank and we have not even looked at the rods and pistons yet. And from all the evidence we have seen in the past, you would be crazy to NOT have all this stuff checked. So I am just not seeing the huge cost savings in these "ready to assemble" economy engine kits. It MIGHT save an experienced builder a few bucks, because he will check and repair all this stuff himself.....but, the time spent will be passed on to a customer. I still see no savings in it for the "average" guy.
