107cc

Hi I have had this project bike for a couple years and I am finally getting around to wanting to work on it. I bought it for $30 from some one and it came with what is shown here. Also have a partial exhaust and wiring harness that is in bad shape. I am currently looking for more info on this...

i have looked everywhere and i cant find one part compatable for an sdg 107cc speed mini pit bike, help me out please!
