Anyone know what the drive chain type is? Factory issued from Yamaha. Thanks.
Is 520 correct?
Don't know where to look up this info.
I have 15k on the bike and a few links that are bound up a bit and will not come back to life with any cleaner or WD-40 or anything else. I live right at the beach so salt water and sand are a daily grind at this location. I've let it go for too many miles without maintenance a few times. So it's time for a new one.
Also suggestions for a good vendor. Thinking of getting something with a gold / zinc plating that has more rust resistance.
Hey Upsidesown,
Don't know if you were considering it or not, but I would definitely change the sprockets too if you want to avoid problems sooner than the next 15,000 miles.
This link is pretty handy because you can just go out to the garage and measure the thing.
(Quicksilver is correct, at 15,000 miles you should change the sprockets also.)
According to the service manual, under Chassis Specifications, on page 2-9. The chain is a 525V10/DAIDO, 110 links.
And the stock sprockets are 16 tooth front and 45 tooth rear.
I know my DR650SE comes with the same size 525 chain.
Is there a huge advantage to going with a 520 chain? I know the whole rotating mass argument, but if you are just running around on the street, is it worth it?
According to what I can find on the D.I.D. website. They suggest using a 525VX PRO-Street X-Ring (Max. 900cc), or a 520ZVM-X Super Street Series X-Ring (Max. 1200cc).
I think the 520 will give you a bit less frictional loss, but will you notice it.......I doubt it! Probably one of the only advantages you will see is a bigger choice of available sprockets......and a tiny bit of weight savings.
My tough behing the 520 conversion was that the sprockets out life the chain with the oem. So I went with 520 but a 1000cc rated chain. The plates on the links are 0.010" thicker, I would imagine the chain will last longer (as long as the sprockets) than the oem? Time will tell... sprockets are lighter than oem but chain is a bit heavier since its a bit stronger. If you go with a lesser strength chain you will definitely save weight... but like triple said, most than likely won't notice it. But it's cool!
I think you may have used some faulty logic here. The thicker plates make the chain stronger and less likely to break with high H.P., but the rollers are 20% narrower, meaning 20% more pressure on the bearing surfaces when transmitting the same power. If the durability of the material used is the same (it might not be), the 520 chain should wear out sooner.
Got it. Understand that the front sprocket rev more often and the tighter chain radius put more wear on the chain... I'll keep you posted.
Like i said, I started at 25mm and won't touch it. The OEM sort of stretch quite a lot after the first few 100s miles and end up around 25mm slack. That's why I left it at 25mm. It was about at 30 to 35mm depending where I measured at the end.
