Anyone have a 250ex with a big bore kit or 300ex carb or high-rev box?

I have a the powroll big bore kit. It increases the bore from 229 to 249 and raises the compression ratio by about 2 to 10:8, you also get a high lift rocker arm. It works really good. I paid $330 for the kit, $100 to the machine shop and did all the disassembly/assembly myself. you get more power than a pipe but its a little more expensive and not a bolt on. Its worth the money.
