I just bought this bike. I am thinking its like 2003 Suzuki JR 50. Not real sure how to date one exactly. And I want to turn it into a pit bike. Never built a pit bike before and was wanting some suggestions on what handlebars and mounts to get I want the high handlebars or maybe there is a way to raise the factory bars??? And how to stiff up the susepension to hold someone larger. I am new to the this game don't know where to get parts and stuff for these type things. Trying to keep the cost reasonable. Any suggested place to get parts would help too. Just give me a little coaching short story long I guess.
