hiya chap, my advice is unless you've ridden these sort of bikes, ride it first, cause you can quickly end up deciding you changed something for the wrong thing. the first chop i changed, i hadn't got to know it properly and made a right mess of it and it then took me another three attepmts to get it right. the third time, i thought about it, and spent a good month on it flat out and doubled the horse power and nothing of it was original and it cost a lot. in fact it would've been cheaper for me to go out and buy the bike again. these days i can do pretty much anything cheap, but i had to make the cock ups first to learn. like i said lad, do about 200 miles (not neccesaraly in one go) and think about it while you're riding, doing this i discovered i like unlimited power but in the laziest posistion possible. hope this helps
