I was looking into buying an FTZ modified 91 cr250r cylinder and bolting it onto my trx bottom end. FTZ claims 55-60 hp on race gas with this setup. it is a bolt on cylinder with the powervalves blocked off. I'll be running my PT Race 89 pipe and 37mm PJ. anybody else have this sort of setup or ever seen it? I'm just curious why I haven't seen more of it...and any opinions on this? thx
