Engine Mount Dampers Cracking

I noticed when I was working on my bike, that my engine mount dampers are looking a bit less rubberlike than they should. One looks like it has dreadlocks!

It's $85 for a new set, and I'm in danger of running low on "winter project" funds. Can I delay replacing these for awhile (maybe a season)?

I only ask because the engine mount dampers dried out on my car, causing excessive engine movement. This additional engine movement rounded out a half-shaft mount, requiring a $700 repair. I don't want putting off a repair, causing a much worse repair later.

Lemme dig around in my parts bin, I may have some. Not a huge deal so long as there's no obvious engine movement at the moment. They don't see a ton of load or engine movement (car/truck engine mounts take a LOT more load and allow a lot more deflection to reduce vibration, the ones on this bike stay pretty still)

If you are going to wait any amount of time try marking the present location with crayon, soap stone, or tape so you can see any movement as soon as it starts. Make a habit of checking that each time you ride as it will probably make small movements initially before breaking loose completely. If you want you can use the "Sell and Swap" section here to see if anyone else has what you need. Good luck.

and always remember, "Ride until you rot!"
**Really not sure if the Big "C" is back right now
but having to face the fact that this is a lifetime routine
going forward. Five operations done and it still continues.

Thanks guys!

Just to clarify, the mounts are fine. The rubber dampers are what's cracking. It sounds like I can go a season with old dampers.

If I run over a $100 bill (yeah right), I'll replace them, but otherwise I'll swap them out next winter.

Something like rubber, I'd rather buy new, only because they have an age limit. Might as well start fresh.
