i think u shouldnt be doin 180kph on the road..or advertising it ...hehehe




p.s. its called $1.80...

Head stem bearings maybe

must be stuck in fourth.

wheels out of balance, tyres shagged, steering head bearings, disks warped, or bent frame...

As the max speed limit is 110, it shouldn't be a problem... excluding track use of course..

Defenitely the first three unless you had a bingle you havent mentioned.
I am bettting the front tyre is scalloped, but seeing as the first rule is always what have YOU done to it since it was working properly did you balance it correctly? No offence, just following the first rule of problem solving.

maybe the lead balancer fell off ur wheel

Iv had this bike 4 couple of years now and neva had a bingle wether the previous owner did or not I wouldnt know I did drop it twice since I got it but that was stationry and droped it slow cause couldnt handle the weight, like I said it was a slow drop, how ever it only shook at that speed and not any lower, I know I wont b doin that speed too often but just got worried and to answer every 1s question yes I did balance wheels, tyres new but guys some of your coments did help, I will get it lookd at, so I realy mean it, thank you very much

Could it be swing arm bearings? Chain & sprockets?

You can sometimes adjust them in by screwing the...screw thingy in that homes the bearings in place (after you take the bearing covers off it should be fairly obvious what I mean). Just don't overtighten or you'll kill the bearings. But of course, the only way to know how good they are is visual inspection. But it should be a bit easier on a chain drive bike than when I did the XJ...

If its got new tyres and the balance is right it has to be steering head or swing arm bearings. Check both now.
Put it up on blocks under the frame, get some one to hold the bike, grab the front tyre and pull it back and forth (and as you may not feel movement there) while someone has there finger on the join between the triple and the head stem, is there any movement?
Then do the sam to the back tyre and check movement at the swingarm/frame joint, how about there?
Understand this is VERY rough but will give you an idea.
Is the steering "notchy" (it helps if all cables etc are off)?
But the only true way is the visual (noramlly frigs the back ones looking ).
Or it just could be inherent in the bike, have you done $1.80 on it before?

Im guessing loose or worn steering head bearings now...

I will take it to a bike work shop and mention eveythin you guys said cause dont know much about mike machanics my self
neva done $1.80 b4 but done $1.60 and no probs ther, it has to b 1 of the things you guys mentioned so will get it checkd out

cheers for the info

Maybe you can get someone in the Sydney area with more experience to check it for you first? Could save you money being ripped by a shop
