Pretty sure I have a broken isolator. Vibes are unusually bad at certain RPMs, as well as on deceleration. My question is, is it bad to run it this way for a while? I am in the middle of an Ozarks trip and don’t have an option till I get back to Texas on Monday.

Also, I seem to be having a tough time finding a replacement online. Have these become obsolete?

A good isolator will have clearance see red lines.

Thx Teeps. I’ll look into that eBay listing when I have a moment.

My isolator has clearance in that space, but maybe less than the picture. I also had one go bad on a previous bike that didn’t visibly fail. Had to pull it off to see the damage in the rubber.

I guess the important question is whether or not I’m in danger of running g the bike this way till I get back to TX.

Since it is not all of the way down, the rubber webs have not completely torn through. I rode my bike for about three weeks while waiting for the mount to arrive. The vibrations will worsen...

And probably cut out the wheelies for now.

Thx, Mark. I’ve resisted getting the front up as well as cut out the dirt portions of the trip. Fingers crossed.

When it breaks completely, you'll know. My first mount did that. It was sudden and the shaking got so hard that I thought that I'd broken a connecting rod. When I noted that there were no new holes in the crankcase I examined the bike more and noticed that the motor mount was resting on the head of the mounting bolt. It was not a pleasant ride after that.

Each replacement has been about 40k miles apart.

Funny, bike is at almost precisely 40k now.

Made it home from Arkansas without the motor falling out of the bike. New mount should be here in a few days. Thx for all the help.
