When riding my 92 xt600 wi 21000km on it, when your riding it slow like around 25/40mph it has a kinda wobble,, you CANNOT go in a straight line, it weaves from right to left, the weaving is very strange. but on accelaration, the problem goes away.. but whilst cornering especialy on the right bends,, it feels scary.. the wobble is there again..or a should say weaving..I originaly thought the bike has had a prang, as Ive just bought it. only done 200 miles with it,, but this was very noticeable within the first 5 miles..

just below the headstock on the frame just where you would put the oil, theres seems like its kinda rippled,,its not smooth on the tube frame... 6 inches from the headstock id say just about level with the bottom yoke.

I have also noticed under braking.. it dives to the right, as if the bike is gonna fold in the middle.. its very strange..

I have Mitas tyres on it... the front an rear wheels bearings seem fine.. the shocker is damping ok, the forks are dry,so no leaking.. looking along it when trying to ride at a straight line with someone else riding it,, i noticed that the wheels are out of line with each other... the front looks dead straight whilst the back looks like its not in line with the front. in fact the rear looks like a wee bit of an angle.. but the rear wheel is sitting straight in tehe swinging arm with the chain adjusters...the same number at each side on the axle.

all bearings seem ok, as i said, on accleration, you do NOT feel any weaving, but try going slow,,its a different matter...

I did notice that its not the correct front mudguard, also the headlight has been changed to a round one,,an the wiring is all bodged behind the headlight, an the tanks shrouds are missing. an the tank has a slight dent in it.. with me thinking it may have had a front end shunt at one time. but the last owner o 3 years,,tells me he has never felt anything unduly with it...but I DEFINTALEY feel a weave,, the weave Im talkin about feels as if one of the tyres is twisted,, giving that impression,, but the tyres are ok.... any ideas people...... Thanks,... bama3

I'm sure you dont want to hear this, and you probably have half a suspicion yourself, but it sounds like you've been had. Ripples in the frame, wheels out of line, bits missing or replaced - this bike has most probably had a prang and been repaired. Dont believe what the previous owner tells you, he was trying to get shot of it , after all.
If you've only just bought it I'd take it back and ask for a refund. Good luck.

Hi Timus.. yea am actualy thinkin that as well, they ripples am talkin about,, ad say more of some crinkin, jist slightly, but am thinkin that as well, i did call the guy up as he lives 70 mile fae me, an he said that it has been fine wi him an he didnt know about it. I might try an get a hold o a frame, an swop eveything over, as its a great engine in it....cheers

Hi there !

Ive just took a photo of my frame. Mine has slight ripples, not sure whether they`re in the same place as yours. Hopefully the picture will prove useful to you. Let me know if you require any more

yea, but am gonna do a thourgh check

I didnt know that ma pal has a Jig to square bikes up thats maybe damaged,,so hes gettin teh bike this tuesday,, then we`l see,,, but thanis guys fur yer input.. cheers

The "ripples" are marks left by the tube bending machine in the factory, no need to worry there but it does sound like it's damaged somewhere.

Check if any of your disc brake rotors are straight! A bent rotor will cause that!

Also you could have a bent rim, loose spokes or even a problem with the tires themselves..
