Author Message   Bikerrides Posted on Saturday, February 09, 2013 - 07:40 pm:        Is it typical to get more vibes when the shock goes, especially through the pegs?   Cyclonecharlie Posted on Saturday, February 09, 2013 - 09:20 pm:        I don't think it's coming from a bad shock.   Sparky Posted on Saturday, February 09, 2013 - 09:21 pm:        More vibes under what conditions, idling or normal riding? I'd think that if it's more felt in the pegs when riding, that's more likely rear isolators going bad than the shock because as the isolators wear out, they can transmit more metal to metal vibrations from the engine to the frame near the pegs. Typically the shock loses oil through worn seals and this results in lesser and lesser damping over bumps until we're left with the "pogo" effect in which the shock is nothing more than a spring and that can result in hazardous handling in certain situations.   Bikerrides Posted on Saturday, February 09, 2013 - 10:04 pm:        All isolators were just replaced, so that shouldn't be the issue.   Kilroy Posted on Sunday, February 10, 2013 - 06:42 am:        If your new isolators are stiffer than the old ones, you will feel more vibes.   Natexlh1000 Posted on Sunday, February 10, 2013 - 08:59 am:        Also, if it's cold, you isolators will be more stiff.   Bikerrides Posted on Monday, February 11, 2013 - 09:30 am:        OK, here's where I'm coming from on this. I had the rear ISOs replaced about 3 months ago and had zero vibes for about the first 250 miles. Then the shock began leaking oil simultaneously with a leaking head gasket on the rear cylinder, which made the bike run much rougher than usual. At this time, I began noticing a rather pronounced vibration through the pegs and attributed it to the rough running. I had the top end freshened with all new gaskets, rings, carbon buildup removed, and cylinders honed; runs much smoother, but the vibe is still there. Oh, I also had a new front ISO put in while it was apart; vibe is still there. I read on here somewhere that someone had added vibes when their shock went bad and it was explained that the shock is mounted to the engine, which is rubber mounted to the frame. So every time the engine moves, so does the shock in addition to handling the suspension. Could it be that the loss of oil and dampening ability of the shock could allow more engine vibes to reach the pegs. The vibration doesn't feel metallic, but is just more pronounced than usual. Does this sound plausible? I have a new shock that will be installed in the near future. I guess I'll get my answer then for sure, but wanted the opinions of you guys.
