wobble again

[walker70]

Hi,after taking the bike out today I noticed it wobbled at around 25 or 30 miles an hour,thought I had everything good and tight,new front wheel bearing,newly rebuilt front forks and new tires,the only thing I have not changed is the steering head bearings but there is no looseness in them,it only did this one time,other than that is handled like a dream,any input,thanks.

Loosen, remove, clean, check for wear, regrease, replace swingarm bearings. One side worn can cause this.

Okay,I will check the swingarm,it crossed my mind when I was having the problem after I got this bike,come to think of it I had a similar issue on a van, it was in the rear suspension,thanks.

I seem to remember seeing a post on here where someone had found a tool that would remove the left side nut but it was really made for a regular bicycle,it looked like it was on Amazon but not sure???

Do you mean to say it wobbled ... and that it was a "hands on grips" wobble?

My '85 will do that, always (at least since August 1995) as if hands off as decelerate with slightest weight shift forward. Never with hands on grips, even just one hand as then I sit up more and even one hand will dampen it.

It's a Park FR-6 Tool - found at bicycle shops.

Hi,that is the tool that I found,also when it does wobble it seems to do so as I start to roll on the throttle with my hands lightly on the bars,like I say tho it has only done this one time in the last few months but I am still going to recheck the steering head bearings and the swingarm bearings,those are the only ones I have not replaced because they felt good and tight.

if you haven't torqued the neck brg's then that is what i would do . it seems these bikes have a very minimal rake , causing the front end to act like a bad shopping cart wheel . torquing the brg's to a maximum suggested torque ( or even a little more will help these problems ) the only real fix would be to change the rake angle . i think you will find , although the brg's feel good , changing them will also help a bit as the roller balls always roll in the same spot making them wear uneven . if you jack the front wheel off the floor and the handle bars fall to the side the brgs. are definitely to loose.
Also check the front axle caps and make sure the little arrow on each cap is pointing forward ( the caps are cut on an angle , if you look you can see this ). JMO geraldm

I have already decided to put new bearings on it but it will have to wait cause the a/c on my truck has gone south so I need to see what that will cost me first,thanks.
