$19 or less to install the clip and never accidentally tweak it, stretch it, or otherwise damage it on install. (Oh and don't forget to install it the correct direction, closed end forward in normal forward rotation of the wheel/ chain)https://www.motionpro.com/product/08-0230

$89 or less and you get a rivet tool if rivet links are your preference.

Of note, I have seen the same basic chain press kit at cycle gear on sale in the $25 range.. It is not a heavy duty shop ready use every day kit, but I have had one for years now, and it still does the job as well as my pricey one.

Absolutely, and those same type home mechanics install the clip of a clip link type incorrectly and ruin their new link (and chain, swing arm, transmission, hub sometimes) by having no idea how to do the job properly.. So yes, knowing how do the job is kind of an implied requirement no matter what style link you plan on installing Id say.. Strange the way that works..

Re: I need chain advise.

I am curious about the long accepted wisdom of ALWAYS changing sprockets with chain. I suspect that this might be a holdover kind of thing, kind of like changing oil every 3K miles even though most modern oils can easily go MANY more miles than that without any problems. Many people grew up hearing the 3K number and they just can't let it go. Every time I have changed a chain, I have compared the old and new sprockets to each other. There have only been a small handful of times where I could see any visible deterioration of the sprockets, and even then it was barely noticeable. Granted, I did not take a micrometer to them. I am wondering if the original notion came about because of poor grade steel in early sprockets that allowed them to wear significantly worse than newer sprockets? Perhaps quality sprockets now are made of better metals and wear is not as big an issue?

On my KTM, I swap sprockets depending on the type of riding I will be doing but keep the same chain (so long as the chain is good). I always check the sprockets when swapping and so far have not seen any indication of wear. I did the same with my KLR 650 when I had it. In theory, there is no relative motion between the sprocket and chain rollers except perhaps at the tip of the teeth on the sprockets when they engage and disengage. So friction wear should not cause the valleys between the teeth to enlarge. I have seen tips of the teeth wear enough that the tips thin to the point where they can start to bend, but never on any of my sprockets.

I understand the idea behind replacing matching wear items to prevent premature wear on any of the items. But I just can't help but wonder if that really still applies in all cases? My experience is limited to just doing my own sprockets and chains, so admittedly my sample set is small.

I think I say it more like.. Its a good idea, than always.. And its not always

If Im asked to quote a job, it comes with both sprockets and chain.
If not all needed then not all replaced.
Aluminum sprockets do not last long and likely get replaced "Always"

Front sprockets that see more revolutions and wear than rear sprockets often get replaced "often" due to wear.

Rear steel or composite sprockets of good quality with adjusted and cared for chain often outlast the chain.

I have a IronMan 39th sprocket that is on it's....peeeft likely 10th or more chain, just sold it to a guy for his DRZ, it shows no wear.

I have a Stealth sprocket on my VTR that has 36k on it, 2nd chain..teeth show no wear.

I've seen and replaced cheap steel sprockets in under 10k miles...
The OEM rear steel sprocket on my wifes CRF230 , the OEM sprocket is hooked and in need of replacement...She might have put 15 miles on it in the last 3 years, and the previous owner rode it often I guess, but I did not get the impression it was lots of miles, just long weekend "trips" with short rides from camp each day

Re: I need chain advise.

Thanks, that is along the lines of what I was thinking.

I use the Ironman sprockets as well and they last very well!
