ttr50 upgrades

[SIKKO_X2]

gday guys,
i want to get a 50 and modify the Fu** out of it but ive had trouble finding any stock crf50's for under a grand, so im looking at buying a friends stock ttr50. what sort of engine mods can be done to the ttr? i want to put a manual clutch kit, 4 speed tranny and an 88cc top end with racing head as well as alot of other mods. who makes these mods for ttr's?
cheers

most of your stuff will have to be gytr which is like a yamaha sub brand .
but there is a shortage of parts for the ttr and you will most likely have to buy your stuff from the us.
i know gytr make a 88 kit but i dont know about the race head and the manual clutch etc.
