I adjusted my chain slack a few weeks ago and it got me thinking and reading about chain & sprocket wear. Read up and when and how to replace them.
Rear sprocket wear is obvious but mine still looks great. Decided to check the condition of my front sprocket last weekend as it's not visible. Here's what I saw under the cover:
Looks pretty good, right? Well...not so fast. In the greasy grime near the clutch pushrod I found these:
Could not fathom where those came from. Then today I suddenly had a Very Bad Feeling and inspected my chain more closely than usual. I saw this:
Welp. Looks like I've been shedding roller surfaces for some time. Who knows how many miles? That's not the only spot on the chain where they're missing.
I've watched a couple of good videos on how to replace the chain & sprockets feel pretty good about that. What I'm not so sure about is, what to buy?
I've read that the OE front sprocket has rubber on it which makes it quieter. None of the aftermarket sprockets have it, as far as I can tell. So am I stuck buying an original Suzuki part if I want the rubber? Does this really matter anyway?
Note that I have no desire to mess with alternate numbers of sprocket teeth. I'm happy to keep the original "gearing" of 17 and 41.
Let's say I order from SV Racing. Which I probably will, because the Suzuki parts suppliers are going to be way slower, and I want to get riding again. Also, SVRacing prices are significantly better than OEM suppliers.
Do I need an "extra master link?" If so which one?
Any thoughts on a chain breaker and/or rivet tool? Do I need both? I am not interested in buying a $100+ chain tool that I will only use every few years at best. Can I find suitable substitutes, more affordably priced, at Harbor Freight?
Is it worthwhile to upgrade to a 530 sprocket/chain setup? Any downsides other than increased price?
If you're not exhausted reading yet: also curious what's going on that made the chain start falling apart like that, before any significant sprocket wear. This is the set of sprockets & chains that were on the bike when I purchased it, at just under 22k miles. I hit 45k and change this month. No idea whether the previous owner replaced stuff properly (chain and both sprockets all at once) or something else.
