Jr50cc

Recommended Posts

I got my son a jr 50 it doesn't run well there is very little power to it. Just bought a new carb and put it in. Did not solve the issue it will run fine on flat land but up a hill pr full throttle it bigs right down. It also smokes quite a bit also. Thanks

Check to see if the restrictor is installed in the exhaust port. Just pull the pipe away from the cylinder (should be held on by a couple of bolts or screws, I forget it's been years since I've had one), the restrictor is nothing more than a washer they put in there to restrict (reduce exhaust port diameter) the flow of exhaust gas which leaves the bike with very little power. They don't have a lot power to begin with due to having one gear (actually two but first gear is locker out and inaccessible unless u modify it) so it always feel somewhat underpowered. But if the restrictor is installed it will be extremely weak. If it's there just take it out.
