Clunk when changing gears??
« on: July 17, 2019, 12:07:55 PM »
Hello guys,

new here, just bought a 2015 S1000R Sport, around 2 months ago, I have ridden roughly 1000 miles since, and I have noticed that when changing gears to 2nd, 3rd and 4th sometime 5th and 6th but I am not sure maybe I cannot hear it on those gears due to the noise  :008: :008:, I get a clunk similar to the one everyone gets when they go from N to 1st, now its not as loud, but I am thinking that it could be chain wear, I measured 10 links and i am like 1mm or less from the limit.
I am going to change the chain and sprockets soon but I wanted to know if the clunking I am experiencing is normal or its due to chain wear or some other issue.

Thanks

Okay, the clunk. I have been riding BMW bikes since 1971. There are so many methods of minimizing the clunk in many threads. Right now I own a 09 K1300S and a 17 S1000R. All these bikes clunk some not so much. I eliminate it completely by never starting the bike in neutral and never shifting to neutral at stop lights. Just put it in first pull the clutch in and start the bike up. Warm up for 10 seconds and take off. Just put a new clutch in the K bike at 112,000 miles and the throw out bearing was just fine. If the stop is long, such as a train, I just turn the bike off.

Hello, my problem is not the clunck from N to 1st, if you read again, my problem is the clunck happens when i shift to 2nd 3rd 4th.

Try going up the scale to 4 or 5000 RPM when you up shift for normal shifting. Also make sure your chain tension is in the proper zone, the sticker on the rear arm will have the spec, 35-45mm comes to mind. Works better (less drive line lash) at the lower end of the range.
And if your talking about a clunk when up shifting with the quick shifter you need to be on the throttle and it works far better over 6000 rpm. In general I can shift smoother using the clutch (or some of it) than the quick shift unless I'm hard on it going fast and in the upper rpm range.

You don't mention Km's (sorry) Miles the bike has done.
I would had expected if the chain was on the way out that the clunk would be greater as it took up the slack when sticking into 1st which is clearly not the case. I would look at the clutch.
Get your dealer to have a look may save a few grey hairs.
