1200 TRAC

Postby STBear » Tue Oct 09, 2012 3:23 pm



Hello all,

New member here. I've been reading articles on this forum for a couple of months & have used a lot of the info working on my current project - 1984 Interstate. It seems like this bike had been neglected for a long time, and then worked on by someone with ham hands, no book, and no torque wrench.

It only has 24,000 miles on it, but it looks like about half of those miles were done in Baja and the rest in a swamp.

I finally got the TRAC unit apart, and discovered the spring & check ball were missing out of one fork. Does anybody have any idea if this would have made the bike drive funny, or would it just have affected the anti-dive properties? It had the low-speed wobble before I took it apart, but the steering head bearings were really bad (they had rust on the races & balls) and I thought that the bearings were the cause. I was just wondering if the missing check ball could make the forks do different things.

Thanks for all the info.


Any landing you can walk away from is a good landing.
Any landing where you can use the helicopter again is a great landing.

Inoperative TRAC on one side should have nothing to do with low speed wobble. What will happen is when you get on the brakes, one fork will firm up while the other one doesn't. If you have loose front suspension (sloppy fork bushings, steering bearings, etc.) you could get some adverse effects such as yawing from this. But if things are together and operating correctly, and especially if you have a fork brace, you should notice no difference. In fact, some of the Honda bikes (VFR's spring to mind) had TRAC on one fork only.

OK, thanks. I've replaced all the other stuff, so there should be improvement when I get it all back together. Still to go-thermostat, belts, and carbs - already did rear drive, brake calipers, plus a lot of rubber parts that were disintegrating.

When I get this done, I will start on the 84 Aspy I just got. Then I will remotely assist my son in Salem, Or who just picked up an 86 Aspy that was parked for 10 years. I'll probably be back with a lot more questions.

Thanks to all on here that contribute such useful info.

Hi STBear.
I had the same situation with my 86 Aspencade.
I installed progressive front springs and a SuperBrace and no more wobble at low speeds...or any speed for that matter..
This worked for me...

A rebuilt front end and good tires can give you a lot of confidence. Enough to answer the question - what does the digital dash do after 99 m.p.h.? Not that I would know........

Well,......... the superbrace, looks just like the stock brace, on the forks, now. How can it be better??.... WingAdmin, thanks for the reply. I'm kind'a leaning toward, WHEEL BALANCE, altho, the tires were balanced, when replaced. About the steering head bearings, Would they cause WOBBLE?? .. I just can't shake, the wobble.......... no pun intended.... :roll: Again, Thanks,for the news letter..... Don Petaluma, Ca.

I own two 1200s and I have found that if you run the rear shocks under pressured for the load on the bike you will get a tendency for a low speed wobble. Dont ask me to explain the dynamics of it but I can either up the psi on the rears a tad or lower the psi on the fronts and either bike becomes rock steady.
No pressure in the front doesnt seem to matter. It just seems the 1200 doesnt like its rear end sagging low :lol:

Thanks for the info, Ghostrider..... I'll try to run the pressure, above the line, on the indicator.. On the fronts, the pressure is 3 bars.... Don

Absolutely too loose/too tight steering bearings can cause wobble. Try ditching the wheel weights and put Dyna Beads in the tire, so you can eliminate wheel balance as a problem.

+1 on the neck and wheel bearings. They can cause wobble. As badly unbalanced tires or even unevenly worn tires. Dyna beads are the way to go. Ran them for years. A note on dyna beads. If you run a tire especially rear and notice that when you replace it has worn a spot more than the others then the recommended 2 ounces wasnt enough for that tire. Ive only had that happen once with a cheap very heavy tire and the dot wasnt in line with the valve which had a lot to do with it Id say. But when I had to run that same brand of tire again because it was all I could get on short notice i upped the 2 ounces to three in the rear and it wore perfectly even. A ounce to much wont hurt a thing, a half ounce to little will :)

I have new Neck bearings, now. Is the dyna beads, at any cycle dealer, or where can I find them....? I guess I can search that out, here on the site.

Pretty sure you can order them online also. I never have and closest place i can get them is 30 miles away :lol: You can wear out at least three tires on one set of beads. Ive ran them for years now and wouldnt run anything else once i finally tried them. And yes you do take off ALL the wheel weights. :lol:
