Hi Guys, I've been away from the forum for a while and have just re registered. It looks better than ever!
My 1994 ST100 with 145k on the clock, started to get a serious side to side wobble on the handlebars around 80kph, especially if the road is a bit rough.
I started with the easy things and had the front wheel balance checked - no improvement.
I tried to check the stem bearings by putting on the centre stand and pulling back and forth on the wheel. There seemed to be a small amount of movement. I then tightened the top bearing adjuster nut. When I road tested the wobble had lessened but I had overtightened making low speed turning a bit weird. I then backed off the adjusting nut 1/4 turn and tried again. The wobble came back.
I'm assuming the top and bottom bearings need replacing.
Does anyone know where I can get bearings? I live in NSW but any mail order supplier is fine.
OR can anyone think what else to check before doing this?
Should I look at replacing fork seals and oil while I'm at it?
I also need new handlebar grips, any suggestions?
Cheers
