Valve Adjustment and Chain Replacement

Has anyone put enough miles on their 310 to need a valve adjustment and if so did the dealer do it or did you do it yourself? And did they need adjusted? Also do the chain and sprockets need replaced at 12,000 miles like the book says? I hate to think what the dealer will charge to check the valves and replace the chain and sprockets?

Not nearly enough miles, but I can't imagine the valves being out at 12K. I would definitely replace chain and sprockets at 12K. Thats a lot of miles on a chain. Do not use a BMW chain use a quality aftermarket. Probably half the price of BMW and will not show surface rust like the BMW one does. Chain and sprocket replacement shouldnt be too expensive as it's not a hard job. I'm sure any bike mechanic can do it.

Or do it yourself - as you said, it's not a hard job. DID, RK & EK all make excellent chains. Buy the good (expensive) ones - they're cheaper in the long run. Sprocket availability (other than OEM) is an issue at the moment, but I expect that to change.

Oh yeah - and change out all three as a set - both sprockets and chain. Nothing will destroy a new chain more quickly than a worn sprocket and vice versa. DAMHIK.

You'll need a proper chain tool - Motion Pro makes a nice selection - and the cost of the tool will be much less than the labor to have it replaced. And then you'll have the tool.

Where in the owners manual does it say to replace the chain and sprocket at 12,000 miles. Mine does not say that anywhere. Mine is a 2018 g310gs and I am almost ready for the 12,000 mile service, dealer said nothing about changing the chain and sprockets with the service. I was told oil & filter, air filter, R&R front fork oil, valve adjustment, and new spark plug. Cost however was outrageous they want around $650 US dollars for the 12k mile service. I was told about 4 hours labor plus parts.

Unsure about the GS but for the R it is item #5 in the Maintenance Schedule (Service chapter) = "Replace chainset". First shows at 12K, then repeats at 24K, 36K, and so on.

Here’s the GS maintenance schedule. Item 5 is to replace spark plug. Chain & sprockets are not mentioned. See pic...

I believe R and GS have different chains from factory, which might be why service requirements are different.

The R and the GS do indeed use the same final drive chain, part # 33 83 8 566 489 which retails from BMW for about $117 US .

I think the sprockets are the same as well but you can find out by going to the link at the end of my post. The front sprocket and the chain are shown on one schematic but you will not see the rear sprocket part number on this schematic.

The rear sprocket is shown on the schematic for the rear wheel. Do not forget to replace the 3 rubber cush blocks (jerk damper) in the hub. Always replace chain, both sprockets and the rubber dampers as a set. It is also good if you can have the chain replacement and the tire replacement at the same time so you only have to pull the rear wheel once. Most rear tires will last 15 to 18 thousand miles with good riding habits. You will not get that many miles if you are hard on the brake...

Here is a very good parts information resource for BMW motorcycles. It takes a little bit of practice to navigate and I suspect it works better with a PC than a smart phone or tablet but it works very well if you need to get a part number.

GS uses endless z-ring chain. R uses endless o-ring chain. Thats how it is in New Zealand as well. I haven't looked for part numbers, but I suspect they will be different. For US market, they may both have same chains.
