Wynne, as far as insurance goes, some companies here cover your mods under Comprehensive coverage.
somebody does make a high CR piston and cams and fuel module and exhaust.
unfortunately, for us english speaking people, the page is in japanese but i can still read the dyno sheet.
To add to this:Porting will yield approximately zero horsepower improvement. You're more likely to mess up the torque characteristics and idle than add more than .2 hp.
As for polishing, it will yield exactly zero horsepower.
Because he can and he wants to, this is cbr250.net so why not answer his question instead of saying something that is common knowledge...Why waste your money on the 250. You should of bought a 750

I have a whole garage full of toys everything has been tinkered with and a lot more pleasurable to drive and ride something you have tweaked yourself

My Australian friend, I new here in the forum too. You will find here a lot of useful information. I'm already saying thank so much for the things I learned here, and are not accessible in any guide or book.Haha Yeah just noticed that I've been one this site for 3hrs and I'm done already was to much school yard bullshit
I'm keen to know what gains can be had from head and cam mods. Yes, its cheaper to just buy a bigger bike but I like the option of pick it up and ride away after a spill (I've done this). Also an improvement in power to weight ratio combined with magnesium wheels means you'll beat a bigger bike off the line almost every time. Sure, they'll blast past you in first gear but they're using alot more fuel to do this.!!!If you want a fast bike, why don't you buy one, instead of trying to make a slow bike fast? It'll be much cheaper and easier in the long run.
You can turbocharge ANYTHING! Comes down to cubic dollars and how much fabrication and programming skills you have that you can do yourself vs. farm out to engineering shoppes. Lots of custom cutting, welding, wiring, programming and dyno-tuning.Can you really fit a turbo on these bikes? I'd like to see that and know how much it costs.
