Looking at a 2011 zx 10r with nearly 30k miles on in. What are the watchouts for this bike as far as used potential issues? Is there any major maintenance that likely needs to be done at this higher mileage or that is upcoming? The service manual stops at 23k miles. Link if anyone is interested ti the bike I'm looking at. http://www.roadtrackandtrail.com/default.asp?page=xPreOwnedInventoryDetail&id=3772653&p=1&vc=sport&s=Year&d=D&t=preowned&vt=motorcycle / scooter&fAmtRange=4-6&fr=xPreOwnedInventory

Assuming none of these have been done yet, it'll need a valve service, new sprockets and chain, coolant flush, plugs, air filter and a throttle body synchronization (I skipped the sync on mine and it seems fine).

Tires and oil change if it needs it.

Thanks. That's good stuff to know to ask the dealer about if they know of or have any kind of vehicle maintenance records. How much does valve service and throttle body sync cost? Rest of the stuff I'm pretty sure I can do myself.

i know this is a common problem with them (i've got 10k on mine and its already needed done) MANUAL CAM CHAIN TENSION-ER!!!! LISTEN FOR THE RATTLE... alot of sellers will "mask the noise" with a loud exhaust... put your ear close to the right side of the motor and really really listen closely for rattle... they are notorious for needing manual ones, call any dealer/shop and they will tell you the exact same things... the OEM tensioners are garbage...

Wow that's good to know. Thanks for that info.

A valve service and TB sync will run about $550-600USD. Plugs need to be removed for that anyway so throw those on top.

Welcome to the party!

Yeah, what Porschenut said is pretty much the jist of it for that mileage. Aside from the usual stuff to look for, the general maintenance items need to be addressed based on that. Nothing else that I'm really aware of or different from any other bike.

And I would disagree with the camchain tensioner. It's pretty much the same non-return plunger type tensioner Kawi and lots of other manufacturers use. You hear people complain about them because they don't really know how they work and their bike gets "noisy". Being this is a Kawi, it's gonna sound just like that. :ayyy: :helmet:

The OEM cam chain tensioner works with a spring pushing on a plunger. When the chain stretches, gets some slack in it, the spring allows the plunger to move out one notch and take up the slack in the chain. If the slack is enough to make the chain rattle a bit, but not enough to allow the plunger to extend, then you hear the rattle. There's very little to fail on them and cause problems. Most people hear the rattle and will tell you the tensioner is shit. I've adjusted the OEM one a few times and it's pretty straight forward. Putting a manual tensioner can lead to serious motor issues if you don't know what you're doing and put too much tension on the cam chain. That's why they're typically used in race or built-up motor applications, not your typical street bike. An over-tensioned cam chain is much worse than a rattling one!!!

So don't let that scare you away from the bike in question! Good luck with it!

Thanks for the comments everyone. I'll be heading to the dealer this weekend most likely and now I have a bit more knowledge about what I'm getting in to. Any more information is appreciated until then :)
