Check your chain........... - Ducati.ms

F*ck me!! today while at the top of Glendora Mountain Road, the chain got thrown off!

Scared me at first,

I thought that I had lost the tranny. I'm not sure if I had picked up a rock that got caught in between the sprocket & chain and spit it off, or if it came off on its own. The swingarm is now gouged up, and theres a crack & chunk missing from my Shift-tec carbon hugger. F*CK!!

Either way, I found the chain was way, way too loose!

I got lucky as the chain wasn't bent too badly, so I was able to reinstall it (just like when you were a kid on your bicycle) and milked her back home.

I had adjusted & lubed the chain just a couple of weeks ago, (it was pretty loose then) when I did the night track-day & only got 4 sessions in, & 1 canyon day, so really not that many miles since the chain adjustment.

I have 15,000 miles on this chain (original) and I may have pushed it too far..... so learn from me, because I am suggesting that after the 10,000 mile mark, really keep an eye on it, and after you adjust it to spec, and it gets loose really quick, replace it, its toast!

Looks like I'll have to give a call to JC Pak & order up a chain & sprocket kit.

Aloha Alex

Wow that is really scary... glad you are ok. That could be a major catastrophy.

Close call Alex, good you came out on the right side.

On some MH900e's and some S2R's they had some issues with the wrong size shim fitted in the eccentric thus not allowing the hub to be torqued down properly and allowing the eccentric to rotate over time, some quicker than others.

Just something to note for SSS maintenance.

Holy Crap
Did you check the engine case area?
Is that OK?

Glad you are OK Brudda
Got your call and message. I'll call you tomorrow and get you sorted out with a drive kit

disgo duc · Sep 7th, 2010, 2:22 am

thank the lord your ok...from experience i never let my chains go more than 8 to 10k it seems after that many miles the really start stretching faster than ever!on my motorcross bikes especially my 450s i change the chains every two seasons and that taking really good care of them as well.

Your chain should last longer than 10,000 miles with proper lubing and care. What do you sprockets look like? What kind of chain was it?

This clip will give an sample of a day in the life of a chain and why they deserve special attention and care from us.

My stock chain was spitting o-rings at 2500 miles and I ride in a pretty clean environment and am pretty good about maintenance. Others have stated the same. I suspect that there are a lot of chains like this that went unoticed.

I ran min until 5K and changed it out.

Out!
