91 VFR Chain help

So still got a stock chain with 50k miles.

anyone know how many links are on a 91 vfr 750 single swing arm chain. also what's the difference between 520 and 530 chain?

Thanks in advance!

 

There are 112 links on the OEM chain which is a steel 530 size.

The 520 is more narrow and because of this it is lighter in weight and often preferred for racing. For the average street rider the weight savings will be negligible and keep in mind that if you decide to go with 520 you'll need to accommodate for the size difference with new sprockets. My advise is to stick with the 530 size which is stronger overall. RK and DID branded chains are usually considered the best and either should work fine. If you do decide to swap your sprockets too I highly advise going with steel over aluminum which wear out much quicker. A good place to buy everything you may need is www.sprocketcenter.com

What are you using/doing to get 50,000 miles out of a chain? That's a lot of miles.

 

wut the hell kinda avatar is that? You in your wedding duds on a bar-rago? Sheesh. ound: Steel sprockets for street always, 530 chains with o-rings/x-rings/all the funky nomenclature. Gol RK, DID, maybe Regina rhymes with ver-gina...Get a gold chain though, I am vain...

 

hey ride..leave regina outta this

 

I have over 50,000ks on the chain on my CB750F and just looking at it looks like I have another 50,000 left in it, only ever adjusted it once. Problem is I can't remember the brand, I got it with the sprockets from the local Honda dealer back in August 2008 Buy good chain and look after it and it will look after you

 

I honestly don't even know. this bike is just my daily commuter my 87 vfr is my track bike so I ussually take it easy with my 91.

 

I kinda dismissed that claim as an impossibility right away. ig: Never saw a stock or replacement chain that was still acceptable after 25k.:tongue-new: Maybe on a low-power bike ridden most conservatively.

Off the bike, (with link pins horizontal) chain wear/mileage is about proportional to amount of arcing as the chain is stressed sideways. Newer chain at top and 30K chain at bottom. A new chain barely flexes sideways at all.

Other scientifik measure of chain wear is the difference in length between being compressed and stretched out lengthwise. I believe anything over 10% needs replacement, maybe.

 

Ok thanks for the comment on my avatar, however un needed, I actually contrary to popular belief purchase bikes for my pleasure.

And I know I'm seriously surprised it has lasted this long but I take serious care of my bikes I replaced all gaskets at 20k miles, rebuilt carbs at 30 and grease my chain every 3 tanks of gas. I completely de-grease chain every 1k, but I think I found the actual problem.

Though I do need a new chain I also need a new rear sprocket because the teeth are bent forward. (I fosted this thread because I started to hear some clicking in the sprockets and never dealt with it with track bikes because my shop guys usually replace anything before I think about it/feel it
.)

 

That does answer my unsaid questioning. If your sprocket teeth are hooked, that chain is waaaaay past it's "change by" date. You may have 50,000 miles on it but it should probably have been changed a looong time ago. 50,000 miles seemed like too many miles to have on a chain that isn't fully enclosed.

And you should pull the countershaft sprocket cover and check it too. If the rear is that far gone, the front is not likely to be any better.

 

Yea I've ordered a new sprocket kit for the bike and chain.

 

+1 on the Squirrelman, no way that chain is worthy...pull it and do the length test and the bend test to see.
