530 chain conversion (Read 440 times)

Grandparipper TR1 Board Newbie Posts: 9 Gender: Bike: XV920R, SR500, R1200RT, SR500 race bike in parts	530 chain conversion 30.12.24 at 23:28:43 I am sure this has been discussed before. Sorry to ask again, but I could not find what I was looking for in past posts. I have been told that new chains are stronger and better in general. I have been told that 530 chains are stronger enough to work fine in a XV920R, similar to the TR1. I can get 530 chains and rear sprocket, but the hard part is the drive sprocket, often called the pinion. Does anyone know of a Yamaha front sprocket fitment for this bike? Does it require shims or special machining to do this? The goal is reduced weight, friction, and therefore a modest improvement in response and power. Can you direct me to previous posts about this?

If you have access to a spark eroder, you can also modify an XS650 item. Cheers, Greg

The translator may not be very clear. I am not sure what a spark eroder is. What modification needs to be done to an XS650 drive sprocket?

Hence you can do it with electricity, i.e. a spark erosion machine. Cheers, Greg

Very cool, but probably not available to me at a reasonable cost. For just one XS650 sprocket, drilling slowly is probably my answer. Is that the only machining to be done on an XS650 drive sprocket to get a 530 chain conversion done? By the way, I have two SR500 motorcycles! One stock and another being converted back from a race bike to a street legal cafe racer.

Re: 530 chain conversion Reply #5 - 07.01.25 at 13:21:45 Hi Grandparipper, Why do you want to use the 530 chain? The original 630 does its job perfectly,...lasts over 100,000 km, runs smoothly over the sprockets, no wear, no noise. The only advantage I see is, a 530 is easier to get in the shop, ...but costs the same. But how often do you change the chain / 100.000 km ?? Or have you removed the chain case (very big mistake)?? ...because then you will have wear on the chain wheels and will face the same problem again the next time you change them. Greetings Bruno

This bike is a new purchase and I am looking it over carefully. The bike has 83,00 km on it. I do not trust the chain as it has a few stiff spots where it appears to be binding up a little bit. The bike is old, so age is probably more of an issue than km. When replacing a chain, you should replace the sprockets too. I always ask myself, is there a performance upgrade available? As I said in my post, newer chains are better and stronger. A 530 chain is strong enough, yet lighter, so it should accelerate faster and have less friction. This is not a race bike, so a logical question is, will I notice any difference? Will it be a pain in the ass to do the change? Am I saving any money? You are probably right to just stay stock, but it is winter and I have the time to investigate it before springtime riding season.

I do like the chain case, so I am not removing it. That is one of the design features that I really like about the bike!

So the chain will be as good as new, at least if there is some oil or fluid grease in the case and noone has tensioned it too much. Quote: I do not trust the chain as it has a few stiff spots where it appears to be binding up a little bit. Is/Was there enough fluid grease or oil in the chain case? Then normally nothing can happen to the chain. If there is some oil in the base of the case, so that the chains runs through the oil in the lower rubber tube, this will be enough. The tension should be so that the rivets of the chain are on the height of the lower mark at the opening of the rear chain case. Quote: This is not a race bike, so a logical question is, will I notice any difference? I dont think so. Quote: Will it be a pain in the ass to do the change? Definitely!
