ZX2 Vibration survey

I can do that tonight when I get home. You want from outside of the rail on one side to outside of the wheel on the other side right? Do this for all wheels? Mine is realy easy to get at in my heated shop connected to my house so anything you need I'll measure and post back this evening.

Any measurements you could get would be appreciated. I was thinking if you latch the tape measure on to, lets say the inside of the left rail and then measure to the outside of a left wheel. I am looking for the distance from the inside of the closest rail to the outside of the wheel. Does that make sense? It is hard to explain.

By the way I did notice a large gap in my front right rail as you mentioned. I tried getting the track to shift right but it is too close to the drivers to be able to change.

Yep makes sense I will get them for you. I'll take any others I feel are relevant to the track clips hitting the wheels.

Well kinger I am counting on you! ADBoivin threw in the towel again and will not offer any more help "I have no more ideas". Awesome, thanks so much! They don't even try. :o|
 
Some measurements:

Inside rail to outside front idler wheel = 3" both sides

Outside wheel to rib on the rail for both the mid wheels and rear 8" wheels is 1.75"

Inner idlers on front inside wheel to outside rail = 3"

Left rail hyfax to inside of track clip = 1/8"

Right rail hyfax to inside of track clip = 0.5" (looks like I'm off alignment a tad I have NO wear on right side out side of hyfax, very little on the left side, less then rxriders picture)

Just for checking my track the clips are 2" apart on hte predator track.

How close are yours?

It is too bad you are not closer so that we could swap skids!

Everything but the inside wheels match up. Where and how are you measuring the inside wheels? I have a tape measure over the top of the closest wheel and running it to the outside of the rail. I have about 3.25"+.

Also I am not sure what you are measuring with the track clips. What track are you running? I have the Predator 121 1.25" clipped every third. I did run a fully clipped last year and I wonder if that caused the marks.

I am pretty sure you will not be able to get the track to slide over up front.
 
Well I get to Houghton usually yearly so I'm not sure if thats different then houghton lake but maybe something could be worked out. Sorry just looked up your location and your over 12 hrs from me! Shoot.

I measured just like you, clip the tape over the inside edge of the wheel, and measured to the outside of the rail. I did this with the tape laying across the rail so as to not have to 'guess' if i would have had it over the 12 O'clock position on the wheel.

For the track clips its basically measuring the 'nubs' that the drivers use to spin the track and measure the distance between them just to make sure you got 2" and not TWO oddball tracks...its a long shot I know but figured while I was in there with the tape what the heck.
 
Well the distance between the cogs is 2". Measuring like you said the inner wheels measure 3".

How about:

The distance from the outside of one inner wheel to the outside of the other. 5 3/8"

The distance from the outside of one upper wheel to the outside of the other. 13.5"

If those measurements match up then I have no other ideas at all.

By the way Houghton in the UP is many miles from Houghton Lake in lower Michigan. Although I have always wanted to ride in Houghton, I do not want to spend time wrenching in Houghton!
 
I will take a look at my skid when I get the time.

mdkuni - what you said about parking on the side of the trail with one ski up on the bank may be something to look into. It's related to the the wear I have on the front and upper idler wheels. Distance between wheels on the front and upper shaft could be too narrow causing the wheel to start climbing on the track cogs before the slider stops against the track clip and cogs, just a thought. I will look into it before installing the skid, some day soon.

I thought the wear on your wheels was horrible! Mine do not show any signs of that kind of wear. On mine one rear wheel and one front wheel have a small chunk or two out of the rubber but that is it. I think I would be more upset about the wheels then a vibration. Wheels are expensive.

The wheels do seem too close to the cogs especially when the track shifts. To me the vibration seems like it would come from a wheel climbing the cogs but if my measurements match up then it does not make sense.
 
I can think of a few more things that may create vibrations.

worn/broken chain
bent jackshaft
bent drive shaft

you may already have those things ruled out
 
He said he had a new drive shaft, and different drivers as well.

I really wish we could get this figured out.

No vibration with Mono.

Could you check the mount kit to make sure the holes are exactly the same?
 
I have got my ZX-2 suspension bottoming issue taked a care of, but now I have got a vibration issue as well. I have not read through this whole thread, I may if I get some time. But I am getting a vibration at about 75mph and above, anything at lower speeds and there is not any vibration. I believe mdkuni has the same high speed vibration problems. I am not worried about the vibration, I did a very quick inspection after the ride, and everything looked good. Here is a full ride report http://www.ty4stroke.com/viewtopic.php?t=64912
Last weekend when my track tension adjusters were all screwed up I believe I did not experience any vibration at all, however I was mostly off trail riding, but I did get up to higher speeds on the trails at time. Since I did not experience the vibration last week when the track was much looser than it was suppose to be, I may loosen the track slightly and see if that helps at all.
Some other notes
I barely top out over 100mph now on the speedometer on the Railroad grade, when last year I could get to 100 or 105 pretty easy.
I have a Ice ripper track clipped every 3rd.
I got slightly worse gas mileage this ride (12.5mpg) when I normally get 13 or above. -The gas mileage could really before any reason though. I may slightly loosen the track tension to see if mileage increases at all.
