I recently bought a 2002 JR50 for my newphew. He loves the thing and is going to be hill climbing with it next month. The bike runs good but lacks power for sure. Is there any small mods i can do to make this thing more peppy for him to help him up the hill better? Some peoople have told me to activate the 1st gear in this but Im not sure if it has one or not? Also i have heard to get more power out of it to run a small amount of octane booster and drill more holes around the big hole in the air box? Also heard about removing the kickstand and chain guard for less weight. My nephew is on 50lbs wet and I have changed the plug and also change all oils crankcase and 2stroke. Any help on this 1st gear would be greatlly appericated and any suggestions for some small mods to give it more power? Thanks
