Tire "in and out wobble" in 1st on Paddock Stand.

[warp9.9]

OK rotational slop is normal its the slop in between the female gear where the dogs mesh into. Nothing to worry about there. Actually if you have the updated second gear there is even more slop then the original. As for noises I think its has to do with no load on the drive train unless you can hear it going down the road. Try it no rear brakes just front and leave the rear pads loose. The run out did not look bad on the video but without a dial indicator Its hard to tell from a video.
Oh and I see the bushing I was asking about it is in the right place.

It looks like the tire is worn out of round. Ever done any big smokin' burnouts ? Or maybe someone else did before you got it ?

Or the tyre isnt beaded properly

Watch this carefully...I will shoot a longer one to catch the shaft drive clanks....

Looks to me as if the tire is slightly out of round. The rims seems to be spinning true. The out of round condition is probably causing the slight vibration at speed. I would closely check to make sure the tire is seated equally around the rim. If it looks good, check the tread for a flat spot. You didn't happen to brake real hard or lock the rear tire while riding recently? If the vibration bothers you while riding, have the tire rebalanced. This won't eliminate the vibration, but will lesson it. The noise you hear may be play in the drive system (they all have a little), as the out of round/ balance of the tire seems to shake the frame slightly.

@xlr8tion Ok of course you have me thinking. in the video you can see the run out on the rim looks pretty true by eye, and the rubber does look like it has a run out on her. a spot on the tire of discoloration can amplify this. Not that there is not run out. Now The video does not show so I will ask first since the bike is up in the air the swing frame is hanging down lower the normal and compression no sag in the suspension while hanging. What does the shock do when the tire is running in the air. and is the swing frame moving? Oh and does this movement coincide with the knock transmission noise? (erratic loading and unloading of the drive train since it is hanging in the air)

I can say what I would do is run down to the shop and grab a dial indicator and mag base and fist check the run out on the rim both the face of the rim and the inside diameter of the rim. I would do this in neutral by hand so the suspension does not move. Of course I am a Tool Maker so I have indicators up the wazoo If you do not and want to get away fairly cheap Harbor Freight has this for 32 bucks Clamping Dial Indicator

It is not a mag base but you could clamp the vise grip to just about anything. eve a floor jack next to the side of the rim a big chunk of iron will also work. I bet you could also go to some place like Lowes and get on with a mag base instead of the vise grip clamp either way the dial is a 1 inch travel so you have a lot of room to play with. Depending on the set up you could also check the actual rubber if you set the indicator right. (so the rubber grip action does not impair the dial reading. I would first verify the rim is rotating concentric first and then go fro, there.

WOW.....Hey thanks guys for all the input! Thanks to all who are helping me as I just found out about this as I put her on the Flip stand to change out the LED lighting system on the rear.

Here is what I know...

1. The Tires were bought from Dennis Kirk and were mounted at the Triumph dealer I was complaining about in a previous thread for poor quality service. So its a dedicated triumph dealer-if the tire was out of round he would have seen the runout when he was spin balancing it. So if it is seated wrong or was defective from BStone-the tech should have caught that...These are NEW TIRES and I paid 700 dollars to have them mounted and the brake pads changed....And now I am having probs with both....

2. The tires have maybe 400 miles on them..NOT A SINGLE BURNOUT...All normal riding....

3. I will do the things you suggest warp to make it more easily visible and check out those shocks....
If one of the shocks was adjusted in a different position than its counterpart-that would not cause it?

4. I will aerospace 303 the whole tire to take make it uniform in color and reshoot the vid and post it I will check the bead seating and then the shock movement or behavior with the runout going.

5. I am too ignorant to understand how a "tire hanging on the swing arm" affects runout...The left shock bolts to the diff...When the shaft splines were greased that diff and rear axle were aligned proper before tightening.

I will try to located a run out gauge and worst case take it to the Augusta GA Triumph dealer....That will be a $$$ debacle as they hate working on other peoples mistakes and I do not want to take it to the original shop for obvious reasons......

Most importantly......


YOU GUYS ARE LITERAL LIFESAVERS....Like I said I only road the bike 400 miles with the new tires on and it gives me pause what would have happened if the rear tire would have seperated from the wheel doing 80mph..

Back with more vids in a few hours...

Cheers....G

as for the hanging on the swing arm I was more interested if the swig arm was bouncing any which would look worse the further away from the swing frame pivot point. I just figured it might show up in some shock movement. As for the run out at 80 mph I can not answer that one. I can tell you what happens when you inner clutch hub explodes at that speed locking up the engine and drive line

I played the video about 20 times, and pushed it up to higher resolution. You can easily see the difference on the outside of the tire, but if you look at the bead as it runs, a little below the exhaust pipe, you will see what looks like the bead also has some movement. Suggest you look closely at the bead/wheel seating location as you roll the wheel around by hand with a good bright light on it. You may just need to break the bead, lubricate it with some soapy water and reseat it.

 

[Triple Trouble]

I too suspect the tire needs to be properly seated. There are usually thin circular bands near the bead which you can use to visually eyeball how true the tire is mounted. Most tires have a little runout and yours doesn't seem to be extreme. The clunk would be normal for an unloaded final drive as, at idle the engine won't be completely smooth.
Edit: Just watched the vid again and there is a definite dip at one point which to me indicates that the tire isn't seated correctly!

 

[idk]

I agree, the tyre is not seated correctly.
