1982 Suzuki GN125
Nice frugal commuter / beginner bike
The bike had a difficult to diagnose ignition misfire.
Replacement of the stator / pickup assembly cured it.
The starter had a worn output bearing and worn brushes.
I replaced the igniter module, coil and plug cap in trying to fix the misfire.
The carburetor needed to be replaced due to severe old gas blockage.
The bike was a 'basement find', which I bought to fix and resell. I replaced the chain, tires and carburetor after repairing the starter myself. It took a while to find the bronze replacement bearing for the starter, but that has performed well.
The stator replacement was the last item to replace; it did not test out-of-limits per the repair manual.
I've been getting over 75mpg with the bike, even with the misfire. I look forward to seeing the fuel mileage now that it's making full power.
I've been able to get the bike up to 70mph (indicated), but that was with a tailwind. 63-65mph is typical, maximum. I don't ride it on any roads posted for over 55, and recommend keeping it mostly on routes labeled for 50 and under. There's no real acceleration available above 50mph.
The bike is a little small and light for me, but its speed range and fuel mileage make it a useful nice-day commuter. I'm glad to have helped save this little classic and keep it on the road.
Would you buy another motorcycle from this manufacturer? Yes
