• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Belt wandering

On my 2014 RT the belt has always been touching the inside flange. I decided if I was going to check the toe in/out the belt shoud be centered. It took three or four turns of the right adjuster and i even put the belt physically where it shoud be. Started it up while in the air and it went right back to the flange. Where it has been for 10K. Went for a hundred mile ride two up and when I came back the belt was where it is supposed to be. Yesterday I went for a short ride solo, when I got back I noticed the belt is back on the flange. ??? No unusual noises or vibration of any kind. Belt tension is 205 pounds. Any ideas as to why this is happening? Thanks all...............
 
You always need to run the bike forward and straight for about 20 feet or so, before looking at where the belt sits...
Back up, and it jumps around like a toad on a hotplate!! nojoke
 
I was wondering why a Harley belt tention is 10 pounds and a Spyder is around 100. I know the spyder is a little longer but that is alot of difference.

Harley belts are adjusted with so much deflection at a certain amount of pressure applied. For example, one Harley spec is 6 mm deflection at 10 pounds pressure applied. That is about 1/4" at 10 lbs. We are doing the same thing with the Krikit II gauge. The gauge clicks when it reaches a certain amount of deflection. I've never measured the amount of deflection on a Spyder belt when the Krikit II clicks. But it seems to me it's more than 1/4". I'll have to try that and see.

But I think we are looking at apples and oranges here. Measured the same way as the Spyder, I'm sure the Harley belt is much tighter than 10 lbs.

Tough one...

when adjusting the belt you will find that if you rotate the rear wheel 10 times forward you will get the tracking while moving down the road. Then rotate the wheel10 time back and you will see the belt walk away from the inner edge (in most cases). Getting that to be mininal is a challenge. Then you still have tension and torquing the axel (which tends to change the tracking) ....makes you miss the old chain drive...:lecturef_smilie:
 
Adjusting can be tough

I was talking to the local Spyder tech yesterday about belt alignment. He commented most Spyders come from the factory/dealer with the belt riding the flange. As for adjusting tracking he said the difficulty of getting it right varies - a lot. On some Spyders you can get it to track with very little effort, on others you fight it for hours. There have been times he's taken the Spyder out on the road carrying the wrenches with him. He'll ride a few blocks, stop and make an adjustment, ride some more, stop, adjust, and so on until he gets it right.

The important thing, he said, is to get the belt to track off of the flange, even if it is only a smidgen. Even though the spec has been 1 to 5 mm, between the flange and outer edge is what matters.

I'm beginning to think that the belt will change shape ever so slightly after retensioning it, which will occur when you adjust tracking, and that causes it to move after a supposedly successful alignment process.
 
Getting the belt to track properly, at the correct tension, without excessive vibration, can make a person a candidate for the funny farm. :gaah:
 
Tiny adjustments

I get them straight in a jiffy. Use 1/8 of a turn at a time. 3/16" wander is ok, the belt, rubber mounted engine, swingarm. Tiny corrections, and you can get it 1mm off the flange, and minimal tracking outboard. Little corrections, it works!

Dealer replaced the rear tire last week, now it rides the flanges both, rear and front, he says is normal, how bad is it/ will it mess something up?
He don't know how to adjust it me thinks,

Tell him to RTFM. The belt must not run against the flanges.

Answer to 1st Question - BAD!
Answer to 2nd Question - YES!
Response to your conclusion - I Agree!

If you check your owners manual you will see quite CLEARLY that the belt is not nor is supposed to be CENTERED.

I have a 2015 RTS and the belt since new has always been against the rear tire flange. It has only recently cause a problem. When moving forward at slow speed I can feel and hear something making a rubbing sound. I'm pretty sure its the belt rubbing the inside flange on the rear wheel. Does anybody agree with me that this is what is causing the rubbing sound? It sounds like getting the belt to track correctly is a bad pain in the a**. :yikes::yikes:
 
I guess i will take it back and force them to align the belt properly, hope they have somebody competent enough to do it
 
tell them to open the manual it tells YOU exactly how to do it,,Its not hard and takes Patience. It will change once you do final torque of axle..
