universal parts?

[x-rider]

I have been on ebay looking at universal billet parts for my 83 200x. Parts I have been looking at are:

-universal billet front brake clutch and resevoir levers to fit 7/8" or 22mm bars.

-universal billet rear brake resevoir.

-universal billet thumb throttle

- fork boots

Hoping these parts will fit for me. Please let me know what you think.
