Hello all. I decided to buy my 9 year old his first dirtbike. I found a 99 z50r ( i'm assuming it is a z50r but the owner thought it was an xr? ) for what I thought was a fair price. I'll be picking it up this evening and will hide it from my son until I get it fixed up and put a quick paint job on it. It does run but stalls and will spill gas out of the carb if the fuel shutoff isnt immediately closed after running. Is there an actual "carb kit" for these? If not...do they make a knockoff cheap carb i can buy? What is the site with the cheapest prices for parts? I also need front wheel bearings as they are beyond wasted... and some brake pads. Other than these items... it should just be a matter of bending back bent brake and shift levers and cosmetic stuff. I remember the 80's models when i was young were pretty bulletproof. Are these similar in dependability? I also am wondering if there is a way to limit gear selection...or a governor of some type to limit speed? Any help is greatly appreciated...Thanks everyone!!
