bbk ebay
 

there are hundreds of these kits with lots of different prices.which ones are good and which ones to stay away from

I bought a 47mm bbk off ebay from scrappydog last year and I can't say anything bad about it. I've put over 600 miles (1000 km) on it with no problems. I also upgraded my carb and airfilter at the same time. I can't speak for other kits but scrappy's is working well for me.

okay thanks

Dwint, a BBK is not going to give you the performance gains you imagine it will.

Some kits are bad quality pistons, the piston is actually hard to push through the cylinder, scrappy dog, and my kits are good quality, it took us a lot of trial and error to find them

thanks
