Front end vibration

[MONK]

Manufacturing Defects in a tire (ie. the Vredestein's ) is NOT common ....un-like KENDA's .... alignment should not cause SHIMMY, unless it's off the charts BAD, and then it wouldn't even be drivable ... your REAR KENDA is where I suspect your issue is..... good luck, keep us posted .... Mike :thumbup:

Not that I doubt you, Mike, but I get a vibration mostly in the handlebars. How would a rear tire issue affect the handlebars?

swap the wheels from one side to other see if the problem moves

Great idea but it's not limited to one side or another. As noted, I feel it the most in the handlebars.

what kind of balance beads you use?? reports of some brand clumping up sitting, then takes a few miles to get them to come loose?? posts are on here of the brand

Counteract, as suggested by a few here. I rode down the highway for a good 10 miles before I turned around and rode back the same 10 miles. (Plus the distance to get to the highway and back.) Not saying that the balancing beads aren't part of the problem but I would think they would have unclumped.

I'll take the bike to the shop next Saturday and let them figure it out.

Since you seem to believe that everything possible has been done to BALANCE the front tires and has been done correctly .... Then the only thing we are left with ( based on historical data ) is that Kenda tire has internal belt issues. ,.... Mike :thumbup:

Good question, but I can tell you when I had a pebble stuck in the rear pulley the handlebars vibrated. That's one reason I kept focusing on the front tires until I happened to see the pebble!

 

[MONK]

Guess it's time to jack up the rear of the bike to see if I can find a pebble, eh?

HEY MONK, I just had the same issue in July, intense vibration in the mirrors and handle bars till the rock got pushed through the belt and it self centered. then the vibration went away. only found the rock by visual inspection. cost me $600 for new belt and Lamonster roller.
T.P.

I just jacked up the rear of the bike and laid down next to it (not an easy task these days) and slowly spun the rear tire around, first looking for anything caught in the rear sprocket then checking the same on the belt, both tooth side and other. Nothing. I guess the shop will have to figure this out unless I happen to have a rock stuck in the front sprocket (I'm no longer equipped to remove that many body panels).

I appreciate all the help, guys. This is baffling although I'm sure someone who knows these bikes in and out will take about 10 minutes to say, "there's yer problem".

Woodaddict in note #20 mentioned Dyno Beads clumping. I had that and it was caused by the MOISTURE from my air compressor air mixing with the dust in side the tire to clump with the Beads. Didn't know they were clumping till I wore the tire out. So I guess they still work. Just wanted to share that.

I'll echo what Peter said about beads not always being enough. I replaced my tires with the new Quatrac's and put the standard 2 oz front, 3 oz rear Centramatic bead kit you can get on Amazon. I found that my right front wheel was shaking most of the time. Seems like sometimes the beads worked but other times they did not and was inconsistent. I supposed I could have just tried adding more beads but I decided to remove the beads and re-balance with weights. Now it's smooth as silk!
By the way, Marc Parnes sells a nice balance kit specifically for the Spyder. http://www.marcparnes.com/Can-Am_Spyder_Wheel_Balancer.htm

Oh and also, these new Quatrac's are fantastic. Tremendous grip on curves! I also noticed that the Spyder is less squirrel-y on gravel roads than the OEM Kendas.

Just got back from the dealer. They dismounted the tires, removed the beads, remounted the tires and balanced everything. Smooth like it should be. They said another couple ounces of beads probably would have taken care of things but I'd rather the tires be balanced the "right" way.

Thanks for everyone's assistance, posts, etc.

Interesting Monk, makes me wonder about the beads. I'm tempted with the Ride-On product.

 

[MONK]

Bill---I think I just didn't have enough beads.

You trying to get rid of me, Bill? I hadn't planned on going anywhere. I just can't ride much anymore.
