Motorcycle Repair: back tire wobble, gsxf 750, suzuki katana
Are bikes
I just bought 1990 Suzuki Katana GSXF 750 it has a back end wobble it had been setting for a while got it home changed the plugs and it stared right up.

Tuck it for a spin and it rod nice. Then I oiled the chain and cleaned it got rid og all the oil it had on the motor and now it has a bad wobble at low and high speeds can you help?

Answer
Sounds like you either have an oil leak that is getting on to the rear tire and causing it to slip, or you have an axle nut that has loosened and caused the rear wheel to come out of alignment. Those are potentially serious issues that should be checked out by a qualified mechanic immediately. I suggest you do not ride the bike any more until the problem is fixed.
