Just found my font isolator torn. What are your opinions on just replacing the front, or doing all of them? I think there is about 15,000 miles on all of them. I also see that the new rear isolators use a torx bolt can the original allen bolt still be used.

Keep the OEM ALLEN BOLTS !!!

If The REAR ISOLATORS are still good there is no reason to replace them !!!

Just PM me for FRONT ISOLATOR HELP "INFO" copy ...

My bike has 18000 on it and the isolators are in the lower left hand side. That means all good right?

Blk, you can do just the front. Yes the allens can still be used. Or if you buy new from American Sport Bike, they will give you new allens with them.

Blu, yes if the bolt is offset like that, it is they way it should be.

Thanks for the info. I just looked at my S1 and there appears to be sag at the rear isolators, but it is opposite of the way I think it should be. I also looked my S3 and S2 project and they seem to be pretty much square across them, if that makes sense. No evidence of tearing on them.

The rear isolators look saggy to begin with due to the center bolt not being in the center.

The real test is to lift the tail and look for movement.

Not meaning to hi-jack a thread but the topic just says "isolators" so thought my question would fit...

How critical are the index pins? Do they simply provide correct indexing of the isolator for proper installation or do they actually provide structural assistance by keeping the ISO from rotating?

The indexing pin on my x1 sheared off and I can't get a new pin installed. I thought that at only 3mm long it might only provide an indexing function so I worked out another process to index the ISO for installation then used tape to draw a long from inside the ISO to the frame to check for movement/free rotation...

So far no movement..... It would have been easier with the pin for sure but I think I am good...

Thoughts or similar experiences?

Bike is an X1 and the ISO bolt was installed to book spec torque without any rotation of the ISO.

Seems to be mostly an alignment pin to me Jolly . Being a spring pin in mine I can't see that holding any other function . To keep the thing in place until bolt is tight. It may offer some support if it were to come loose but not for long.

I do know when they fail, it is usually due to rotation, and that little hole gets torn in the process. Then again, most of my experience in working with these type isolators comes from custom FXR style frames where the isolators have a lot of twisting load put on them, unlike the Buell frames.
