Extremely difficult and expensive to build up 250 engine for most people without their own machine shop. You're looking at couple grand total at least (or more). Need big-bore pistons and lots of machining to fit those pistons. Also need bigger carbs and lots of dyno-tuning. Highest we've seen is about 46-bhp and not sure how long that engine lasted.
For $200-300 you can pick up 60-bhp EX500 engine and carbs. Or better yet, aftermarket EFI system for $300-400 more.
