RT Rear Shock Noise?

[polygonguy]

Just wondering....we have had our new RT's about 3 weeks now. If you hit a good bump in the road they both have a clunk in the rear end. It sounds like it must be the rear shock unloading and stretching out? It must be common because both bikes do it. I was wondering , though, if I have the air too high. They are both set on about 75lbs...the max being 90. Any thoughts? I haven't tried less air, but just wondering..???? Thanks for the comment and/or any insight...

It seems fine in the garage doing like you say...the only time they clunck is if you hit a leaping bump...it seems like they extend to their full extension or something??? Both brand new bikes do it...I have to take them back in @ 300 miles. I will ask then...just wondering if anyone has heard theirs do that riding...

They are the manual adjust and both are set to between 75 and 80 lbs (max is 90)

That is a lot of air, unless you are hovering near the Spyder's cargo weight maximum. I suspect your rear shock is topping out. I'd decrease the air to something near the amount recommended in your manual. It can't hurt to try. Continuing as you are will eventually destroy the shock.

Could there be some shock-mounting bolts loose?? :shocked:
When the Missus and I ride double; we normally will run about 60 psi...

I am going to drop the air to around 60 on both and see what that does... thanks guys...

I'd go lower, to about 40, to test it. If that does the job, it may also be sufficient for your riding style. The minimum is 10 psi. On the Spyder, the centered rear shock has much less to do with cornering stability than the fronts, so it is more a matter of riding comfort. After you test the waters, set it where it feels good. That could well be different for the two Spyders with different riders. I'd sneak up on the higher settings if it was me doing it. It costs nothing but a little time, especially if you have an air source at home. BTW, the air fills and bleeds quickly, so take it easy when adjusting...and use a good, trusted air gauge.
