For Gods sake don't remove the kickstart - you're gonna save a few ounces and have to bump start every time. It really isn't worth it.

You can go to premix for safety sake, but I doubt it'll gain you any power, and suspect it hardly uses any either.

The wire splice or HRC box, decent exhausts, HRC kit and rejet to suit, together with a modified airbox should see you in the mid sixties. Loosing the filter is worth a few HP too - 3 on mine.

Have you hacked off all the un-neccessary bits? Rear subframe, junked the rear brake master cylinder, lightweight racing chain, coolant expansion tank, rear footrests, silencer support brackets, speedo, excess wiring no longer used (lights, horn etc)?

As you only weigh 60kg, I won't suggest you diet!
