Your not going to get 100 HP out of an Aprilia either!

For information on de-restricting the bike, check out http://www.nsr-world.com/ Look in the tuning section.

As for removing things from the bike? I remove anything that isn't used. If you switch to pre-mix, removed the oil pump, and oil tank. If you don't mind push starting the bike, you can remove the kick starter, and gear, blocking off the hole. Remove the rear passenger pegs, the kick stand, replace the pipes, remove any lighting that is used for street, remove any electical stuff used for street, etc...

it's all standard stuff... you would do this with any other bike.
