Headshake

I may have experienced my first headshake at the track yesterday.

At the straight away from the pits, i WOT on 2nd gear and was almost redlining and had to turn. So I hit the front breaks and handlebars started shaking. As my speed slowed I eased out on the break and it stopped in time for me to turn.

Also there is some "clicking" sound sometimes when I apply my front breaks. It feels and sounds like it's coming from the right side of the front end.

Oh and I dont have front stabilizers yet but am looking into it now.

The "clicking" could be your rotor buttons under stress or your bearings between the triple clamps. May need to adjust/tighten/service the bearings in the head tube.

i think perhaps when you slammed the brakes you locked your elbows, creating too much inout on the handlebars..that is can headshake.

grip the tank with your knees when you brake hard and keep the arms loose.

ha! Im sure Tim is pretty cool about his parade laps, but a noob running WOT seems like it could lead into a "ruined it for the rest of us" situation.

wait till you see the parade lap video I have lol. I was dragging knee following others on the parade laps videotaping


Check air pressure first,

Check wheel for straightness.

does shake happen when cold? or only when warm?

+1 on the headnut bearing as I mentioned at the track.

A steering stabilizer is only a bandaid for the issue. I dont run one on the hyo, the katana didnt have one.

+1 to cali. Never ran one on a bike that I have tracked and I like it that way. My old 1000 would headshake some, and I put a damper on it. It didnt really help at all to me. I fact I didnt like it over the stock one with thicker fluid put in it.

LOL....yea, people were hauling azz on that parade lap man!! But thankfully no one crashed! Do all parade laps at GSS run like that?

That is because I was busy moderating everyone's speed on the track that day.

I agree, although I have seen people go down on turns doing way less than I was doing. I knew I had enough time to slow down before the turn.

Bevo, on the other hand, was going faster than me on that straight liter bike

Check air pressure first, checked night before that day

Check wheel for straightness. I will double check tomorrow although I could swear it is.

does shake happen when cold? or only when warm? first ever incident that day = warm

+1 on the headnut bearing as I mentioned at the track. Headnut = nut in the middle of handlebars correct?

A steering stabilizer is only a bandaid for the issue. I dont run one on the hyo, the katana didnt have one.
Thanks again cali.

Ares,

Do you know if the bike was wheelied a lot before you got it? Over time that can easily get the bearings out of round real quick.

If you feel comfortable doing it yourself, take the triple tree off, and get into the bearings, check for play in them (worst case is you pull em off, and bearings fall right out of the cage. that's bad)

easiest way to tell if it's the bearings in the head, just elevate the front wheel. grab the forks, and pull forward/back, and side to side. The unit should smootly turn from lock to lock as well. If not, it is possible the head is tightenend too much, or simply worn.

If they are too tight, it is best to go ahead and replace them (depenidng on how tight) you can get away with it for a little bit(loosening up to stock.) Allthough, getting them to stock setting, is just as CALI sez, just a bandaid for a problem.
