I've read a ton of threads now on the conversion / swap kit for the DB 30. I picked up mine a couple years ago and my boys liked it at first. I liked it because although I could not really ride it given the tiny engine, it reminded me of the one I had from sears as a kid.
the boys are bored with it now but I know if I swapped the engine using CJTMINI's kit they would filp. I also think it would be a great project for them to do / learn a bit about how the whole thing works.... The are sorts nuts and have not spent time pulling apart their bikes or our mower the way I did as a kid (I never got good at puting togeather again though)
CJTMINI ... can you let me know how to buy your full kit? I want one for sure!
