Chain /sprocket question

Hi Andy,




Hi Andy,
Unfortunatly i had replaced my knackered oem chain n sprockets at 7000mls for a 525 14t front sprocket n Talon rear so im putting the failier down to, too much stress from the 14t sprocket and wrong chain ajustment. I was very lucky regarding damage just the rear chain cover it could have been alot worse.
Interesting point regarding preload i have'nt played with this yet, so do i just crank it up abit? at the moment i am running sport n Touring fully cranked [2 people plus luggage] with just me on it. I should go and get my suspension set up correctly but in S/Ireland they are few n far between.

Thanks Nigel

 

So you don't think it's anything to do with changing to 525 from 530?

 

Sorry
Yes forgot to mention that bit, yes that was one of the factors also but at the mo thats all thats available :[

 

Decided to clean out the Front sprocket today after cleaning the chain and whilst the chain (after a clean) and rear sprocket look good the front sprocket is shot! that will need a definite change at the next service.
Now the big question do I trade it in now (after the 22,500 service) for a new 12 model or keep it for another year?
The service with chain and sprockets will be expensive and am thinking about adding a Leo Vince de-cat and pipe if I keep it another year.

Decision time soon.

 

Thought I'd dig this thread up as my chain snapped on Tuesday (MTS1200). Nigel, you were lucky; mine has cracked the clutch casing and it's at the dealers now for them to check if it has damaged the crankcases or not, hopefully not... could be a v expensive repair.

13.5k miles. Doubt it'll be covered under warranty but will ask...

 

I have a 530 14T front sprocket - not cheap though....

 

So while we are on topic, what is the uber (Gold for Andy chain to replace OEM one?

 

I've been reading these threads and I'm a little confused or maybe just stupid? I don't understand why you would adjust a chain with a rider on the bike. If you look at the diagram above (which appears a pretty accurate representation) the chain would be at its tightest when sprockets and swing arm pivot are in line and I would assume that the Ducati engineers have made allowances for this. After checking my bike with some weight on it, it doesn't take a lot to compress the suspension enough to get the sprockets and swingarm pivot in line. If I'm missing something then no doubt someone will educate me. I have recently changed the chain and sprockets after 14700 miles and never had a problem. I'm a fully qualified engineer used to repairing everything from lawnstrimmers to HGV truck including plenty of motortbikes, I'm always willing to learn something new so if I am just being thick hopefully someone can explain. I'm genuinely interested. Regards Mark.

 

So what replacement chain and sprockets did you use, Mark? At 14,000 miles my gearbox sprocket is getting a bit hooked and will need doing by 15K.

 

I like using original sprockets as I believe they tend to last longer, I bought the original Ducati chain kit. It retails at £280 but after a little discount form my local Ducati dealer I paid £250. Easy enough job to do as long as you have stand that allows access to sprocket nut (which is as tight as the wheel nut and you know how much fun they can be to undo). Hope this helps.

 

Think I must be one of the few who in 12000 miles that have never adjusted the chain. Left it to the dealer; if it needed doing between service then JHP would do it while I waited and so far have not charged me

 

My dealer put a new chain a sprocket on for me at 13K miles (FOC while they were doing the 15k service). The Ducati C&S kit seemed very expensive to me especially given OEM chains are usually not as good as top end aftermarket items. They had a look around for me and I went with OEM sprockets and and an EK Gold x-ring chain, chain and sprockets came in at £180 which given the rear sprocket is about £70 isn't too bad.
