Question about 1989 Suzuki GSX-R 750 K
Hi I own a '89 Suzuki gsxr750 slingshot. K model to be precise. I recently took a bit of a tumble. Low speed drop and since then my bike has behaving strangely on the road. There seems to be a slight "wobble" or shimmy when I turn or decelerate. For some reason and I assume it's a good one, my bike just feels "loose". I can't find a better way to describe it. I am in the dark, though I've thought of some possibilities. Steering Neck Bearing, front wheel out of balance or even bent fork, though I cannot see ANY bend of any kind. I would greatly appreciate any feedback. Thank you Riaan Venter
I would start at the top of the front assembly and work down.The easiest way to check for a loose or damaged head stock bearing is to put the bike up on the centre stand,have someone push down on the rear taking all weight off the front tire, and push the tire assembly in and out.There should be absolutely no play in the wheel assembly or headstock. The drop may have backed the head stock nut off just enough to loosen the assembly. I would also check to make sure there isn't a slight bend in the front rim.Check the brake caliper for clearance and don't rule out the tire it might have damage you can't see.You may have even bent the front axle slightly.This might explain why you only feel it slowing down or turning.Good luck

You should be able to drill out the A/F caps on the mixture screws if they are still in place. It sounds like you still have a blocked pilot jet circuit though if it runs well at higher revs when the main jet takes over.

The forks are twisted, probably nothing more. lean the front wheel up against a hydrant or the side of a garage, and tweak the bars straight. That's the quick-'n-ez way. The conscientious way is to get the front wheel up, loosen the pinch bolts on the triple clamps, straighten the wheel, and torque everything back up.
also take a close look at the bars and decide whether they are tweaked too.

It sounds like out of balance in the front wheel somewhere. Possibly a bad front tyre, the tire is damaged, bulged or blistered, or wheel buckled or simply out of balance.
