Title: Ducati Monster 695
Post by: rewers on March 26, 2015, 05:13:20 AM
Hi guys, i need your regarding shifting. Thanks in advance.

I'm riding Ducati M695 with 22k km on it. I noticed that after i replaced chain (not sprockets) can't get into all gears as smooth as before (downshifting is OK). Please note that this mostly occurs when shifting on higher revs, 7-8k RPMs, on lower revs can also happen but rarely.

Very common pattern is when shifting from 1st to 2nd gear.

My mechanic claims that old sprockets are still OK.

Please note that even with the new chain i still have gap feeling on throttle and still makes terrible to ride when engaging/releasing throttle, and of course changing gears.

My question is: would i have problem with shifting gears on higher RPM if sprockets or chain are not in good shape?

Many thanks for your answers

Cheers

You might want to check the slack of the chain as described in the owner's manual here: http://www.ducati.com/services/maintenance/index.do (http://www.ducati.com/services/maintenance/index.do)

I don't know if that's the issue, but it's a good place to start.

Many Ducatis aren't as smooth as we'd want them to be - most of us learn to live with it and smoothen things out with the clutch. Of course, if it needs a service, that's another story. Also, a 14 teeth front sprocket helps.

rule of thumb is to replace chain AND sprockets . . .

check your oil level, between marks in sight glass with bike cold and straight . . .

also check for front sprocket tightening  . . .

Not essential, but usually a good idea to replace chain and sprockets as a set, as already mentioned.  Probably more a factor of extending chain life than anything else - they kinda wear together.  Definitely verify proper chain tension and clean/lube the new chain.

On the throttle action, you can lube the throttle cable and adjust the slack.  You can also remove the throttle tube and make sure everything is clean on the contact areas and operates smoothly.  There is also the option of a G2 throttle tube and/or a non-linear cam that can will crack the throttle more gently.

Finally, if the tune is poor cracking the throttle open can be a bit abrupt.

Well i also agree that is good to change sprockets if replacing chain..hmmm how can i put it as example.. after 15000 miles if chain is worn i believe sprockets will be worn to. Correct me if im wrong here :)

14T raises the revs you're in at a given speed - easier to control - less low RPM jumping.

My experience is that sprockets last longer than chains, but it's fairly easy to see how the teeth look. They usually change shape with wear - going from both sides of a tooth having the same shape to looking more like a shark fin.

This is what I experience when there's too much slack in my chain. Check your chain tension, as stopintime recommends. Be sure to check your rear wheel alignment while you're at it.  [thumbsup]
