Bigger carb?

Don't add a PCV

Weight reduction may be your biggest gain, especially gyroscopic (if that's what you are after)

Hi Pete
I will look at making a boost bottle soon

seriously, don't bother. on a machine as small (slow) as this, you'll hardly notice. i don't think they even have gears, do they? not to mention that the science of boost bottles is almost as complicated as chambers. as far as i understand, boost bottles only really help in race situations in that they increase torque and hp slightly before and after the powerband, so you can run corners is certain gears without falling out of power so abruptly. or something. i don't really understand how they work. you've also got to change your jetting if you install one. if anything, putting on some random chamber and boost bottle off eBay will make it run crappier, not to mention a chamber will probably remove any torque you have in the low end (if there was any to begin with)... my advice... keep it stock, imo you're wasting money for very little gain, if any.
