Hi Everyone, Can someone here give me a good dissertation on isolators and replacement? My bike seems to have developed a funny vibration sometimes. When making a right turn and accelerating I can feel a vibe through the seat that I never felt before. The swingarm isolator on the right side has a very small gap between the isolator and swingarm, probably .010", the left side looks to be in firm contact with the swingarm. How about the frame isolators? Are their replacement as simple as removing the bolt and replacing a rubber bushing or am I kidding myself? How can I tell if they are bad, the washer seems to obscure any view of the rubber. I think I may be doing too many wheelies, time to act my age....yeah!! I will read my manual tonight too but you know this group is a lot more help than a dozen FSM's! | ||

if there is a gap between the isolator, and the swing arm, tighten it up...use a torque wrench.... Second, when the isolator goes bad, you will feel a vibration(more than normal)..BUT, it will be sent right to the footpegs, etc... On the X1, the isolator isnt NEARLY as bad to replace as on other tubers, thanks to that handy little removeable piece of the frame.... As far as general condition of the isolators...I will let someone who can explain it better do so... Chase | ||

Thanks Chase, Hope that does it! Regards, Den | ||

If you are talking about an M2 or S3 I don't see how there can be a gap between the isolator and the swingarm. The isolators are preloaded and squeezed between the frame and swingarm. Mark | ||

Den, A lot of times a loose primary will give off some strange vibration. I'd make sure its adjusted properly (way easier than the isolator R&R) before moving on to bigger stuff. Matt | ||

Don't forget the front isolator too. Check underneath. That's where mine ripped. My front crapped out about 5000 miles before the rears. | ||

my front iso went south before my rear isos as well -- front had a circumpherencial crack (izzat a word?) almost all the way round it at 3 years, 35K miles -- 1 year and 6K miles later, I replaced the rears -- no cracks or twisting, but the rubber was galled and looked like a race tire after the race if you're running stockers, I'd advise replacing em soon -- the rubber ages non-gracefully in the atmosphere, specially near urban areas, in my experience | ||

Where is the front isolator? The sets of isolators that look like two eyelets and a turnbuckle near the clutch cable and oil filter? How can I tell if they failed? The washer and turnbuckle obscure the view. I put a torque wrench on the swingarm isolator and it tightened maybe 1/16th turn. The gap looks about the same. Felt ok riding in this morning but the vibe has been intermittent so it's not much of a test. | ||

den front iso is up beneath the steering head -- lil doughnut of rubber -- there shouldn't be a gap at all, sir -- if you could tighten it a 1/16 easily (ya didn't say), then the loctite isn't, and the bolt may be walking out on ya -- Service Manual = good! | ||

Thanks bomber, when I got the torque wrench up to about 110 ft lbs it went "tink" and I got a little movement out of it, I took it to 150 and it was solid. The right side does have a little gap, the left side looks a little squashed where it contacts the swingarm and is in firm contact. I will see if I can take a pic tonight. What else could cause this? When I look at the bushings the bike is on the kickstand, could this have an influence? | ||

Den -- I ferget the torque required for these bolts (shame on me) -- sidestand may be having a small affect, but there really should be any gap at all there were problems with a batch of ISOs (new style into older scoots if memory serves) where the lil pin that keeps the iso from rotating was a mite too long, keeping the iso from seating on the swingarm black correctly -- sounds like this might be what you're facing? in any event, something's rotten in Denmark (and it ain't Henrik) -- likely not life threatening, but I'd R&R those isos, if it was me | ||

I read about the iso and pin too long, I wonder if it's a recall item? | ||
| Bomber |
no clue, Den -- sorry | ||

Back in the day, the pin length and isolator replacement were indeed recall items. Check with your dealer and have them look up the VIN. System should list if any of your recalls are still outstanding. I'd also try to dig up the old spec/instruction sheet for the isolator recall, just to have it on hand for the tech if you get it done at a dealer under warranty. I'd not count on them having the accurate information. Henrik |
