Last night, I set out to repair what I thought was a blown left rear isolator on my '95 S2. The bike has about 15K and I am the second owner. When I began the disassembly, I thought the 3 bolts securing the sideplate to the frame were on the loose side. As I pulled the sideplate off, I made the discovery that the isolator was intact but had slipped out of the recess in the sideplate. I was a little surprised as I had never heard of that happening before. I typically ride solo and the bike is never near load limits. Is this more common than I am aware of? Do you think the fact that the sidestand is mounted to the plate lead to the loosening of the fasteners? Side question. I don't recall which isolators came first. The "3 line" or the "2 line"? Thanks! |

Never hat the loose side plate issue. In fact, I think you'll find the opposite. The bolts can ger VERY stuck requiring drilling out to remove. I'm not sure if the S2 isolators were ever upgraded. The late model tubers were but they won't fit the S2 without a fair amount of modification. I posted pictures in the KV earlier this year. Brad |

Yep, the side plates are more often a bear to get off - as in torch, impact driver and lots of cursing. I guess in a round-about way you were lucky I've never heard of an isolator popping out either. Henrik |

I have exactly the same situation with my S2. Last night (while waiting for a new ignition module to arrive, another tale of woe) I pulled my left side plate to replace the isolator - same loose bolt situation - and found the isolator had slipped down out of the side plate recess just as you described. On close inspection and without removing the plate, I saw the right isolator had also slipped out of it's side plate recess. Since I had the tail and tank cover off to replace the ignition module, it was easy to see that the frame had dropped about 3/4 inch and was being supported wherever it touched the engine case(s) and swing arm. Not Good. The frame will definitely have to be lifted by at least that amount to install the new isolators. You most likely have the same problem. I think both side plates must be off at the same time (see the Buell manual for warnings about doing this without the proper lifting devices) to raise the frame back to it's original position. I'm wondering if the relatively loose mounting bolts have anything to do with this. The only other two possibilities it that the frame has spread apart (Very, very bad) or the swing arm has shrinked (not likely). The isolators on my S2 had been replaced before, and while most of the side plate attaching bolts were reasonably snug and probably close to the recommended torque, the bolt that mounts the isolator itself to the swing arm was no where near the 100 ft. lbs. recommended nor was it secured with Loctite. In fact, it was coated with graphite grease. The side plate bolts did not have Loctite, either. Actually, I think the graphite is a good thing, so long as you torque to the proper specs and check the torque frequently. You can get it apart next time, and I suspect that next time will be sooner than you (or I) expect. Good Luck, Buzz |

Were the roll pins in the isolators????? |

I am not alone. Buzz, your situation sounds very similar to mine. My inspection of the fasteners found there to be no evidence of Loctite ever being used and there was some type of lubricant on the threads. I have no idea if the bike has ever been apart before. After my discovery I checked out the right side too. Everything appears to be in order there. I checked the torque on everything and it was pretty close to spec. This winter I am planning on some major work and will revisit the situation at that time. The frame having spread is worth further investigation. I was not really thrilled with the amount of compression on the isolator after I had re-installed it. S2pengy, the roll pin was in place on my bike. I don't see it serving much purpose other than as a locating device. Thanks all, E |
