Chain jumping
 

Old chain and sprockets done 20k miles and was jumping about lots so I have changed them.

New chain is on and jumps a little but nowhere near as bad as the old one. I can feel it jump when I'm riding.

•Bike is a 2005 SV650s
•Brand new chain and sprockets
•Chain tension is 35mm
•All chain links and rollers are free moving
•Oil level is bang on half way between F and E
•Cush rubbers in good nick
•Every nut torqued up
•Wheels aligned and chain running straight.

Think that's everything.
Could you advise on my next thing to check over?
Thanks

Coolant level / renew?

Re: Chain jumping
 

Coolant changed about 6k miles ago ish. Will check the service book.
How would that make the chain skip around?
Level is about 3mm below Full

Oh, I though you were just stating that you had put a new C+S kit on and were asking what to do next in general. I don't know why the chain is still jumping. Try putting it on the 20mm side of tension and see if it still does it?

Re: Chain jumping
 

that is perfectly normal while sat on a paddock stand in gear and at tickover or slight throttle.

Re: Chain jumping
 

Probably quite normal.
The V twin has firing impulses that are not evenly matched, so the chain is only 'driving' the back wheel part of the time. At low revs this would have the effect you can see and feel.
If you can follow this you're doing well!
I lost the plot on line two.
Best of luck.

It's about to implode. Quite clearly it's a sign to get a new bike, something like a Tiger 800?

Re: Chain jumping
 

Correct chain and sprocket combo?

Did you buy separately or as a kit?

Never ever heard of this on a new chain. Never had this. My Bike has had a few chains over the years. Tighten chain a little more to see if it resolves it.

Looks a little slack to me. My manual says 20-30mm, and I always recheck after the first ride. Chains commonly get a little longer after they've been run in.

Re: Chain jumping
 

Still does it at 20mm. I have always kept SV chain at 30/35mm of play but can't say I ever noticed it jumping about like this before on any of my bikes.

Chain and sprockets correct match, matched up with the ones I took off too although obviously the old ones were very worn.

I'll just keep an eye on it. If people say its normal and they have this jumping also then I'm not that bothered.
