Well folks, I made it!
After a twelve hour drive, I now own my first Ducati Monster!
11 796 that had under 630 miles on it.
I rode a 796 with a 15t front sprocket demo bike and noticed the lower rpm chatter. 14t was suggested to alleviate.
So, before I picked up my bike, I had the 14t installed so I could be freezing my ass off riding my new monster. The next day when I was coherent enough to go for a 46 degree ride, I noticed a fairly significant amount of chatter still(same rpm range as the 15t). I cruised around (5-10 miles) and put it back in the garage. I noticed after doing some manual reading that my chain had a lot of play. More then the manual suggests. Could this be causing the chatter? (Side note, I have the 15t sprocket in hand, so I'm pretty sure they did the swap.)(also, the 14 was for a 796)
Also, if its the chain latency, could someone point me to a good illustrated chain tensioning guide for a SSSA? I'm used to old jap bike tensioning, which is slap-dash and simple.
Thanks in advance.
What RPM range are you talking about? New Ducs do not like anything much lower then 4k until they are broken in. Hopefully someone can link you to a workshop manual for the newer bikes to help you with the chain.
And over loose chain can cause a herky jerky feeling - especially during throttle transitions.
No visuals on hand but it's a super simple procedure. You'll need the right sized spanner, that's the one catch. Should have a torque wrench too.
- Loosen the two nuts at the back of the swing arm, behind the eccentric hub.
- use spanner to rotate the eccentric hub until the chain is properly tensioned.
- Tighten the two nuts to the recommended torque - tighten in 1-2-1 pattern.
It's a really simple job.
Rpm range is between 2-4k.
Is there a special tool needed?
I had a rattle with my 796 that seemed to be chain related, but the tension was within spec and the noise persisted after swapping to a 14T sprocket. It turned out to require chain lube, despite only being a few hundred kilometers after being lubed. Others have reported their 796 Monsters requiring more frequent lubing to prevent the noise. I can't say this is the problem you are having, but it's a possibility.
I appreciate the insight bishamon.
You'll need the correct sized spanner.
Even with a 14t - 2k is too low.

Exactly.My Duc will cruise at 3K, but if you want to eliminate the jerkiness from accelerating you'll need to shift down a gear to pick the revs up.
All the 14T sprocket does is make it easier to eliminate the jerkiness in low gear at take off.
Yeah, I think the first issue is that I just need some more time riding it, getting used to it. My last bike had a good amount of torque and I could creep it around town low RPM. Personal adjustments need to be made.
But in all honesty, I think the chain is way too loose also...
This is the tool I need? http://www.monsterparts.com/pc/CI-SWINGARM/MAINT-TOOLS/CI-SWINGARM.html (http://www.monsterparts.com/pc/CI-SWINGARM/MAINT-TOOLS/CI-SWINGARM.html)
Give monster parts a call to double check that if fits your hub, just in case. But that should be the one
