No I did a search here for "JR50 MODS" and come up with some thing about it having 2 gears..It come stock in 2nd...you need to mod some thing in the gear box to get it in 1st(For the bigger hill)...But I dont know WTF they were talking about??
My son is a VERY fast learner and had is firts race last weekend (Got blown away by the KTM50's)...So I am looking around for some things to do,for now till he gets bigger then the bike goes to his sister, to make it go faster. I odered a "Fatty Pipe" that will come by the end of the week...Now I am looking into the sprocket thing...been looking around but only found stock ones...

1. Looking for the Gear Box MOD...
2. Looking for a bigger rear Sprocket...
3. Anyother Mods...(New or Shave the head, bore out the cylinder 1-2-3mm???)...
4. Just Break down and get him a better bike (KTM50...???)..
