As the title says what chain 1/2 link are people having good luck with? Adding a weak link to the system makes me nervous but if others are having good luck I will give it a shot.

I'm on a 530 and want to try 15/17 & 17/20 but can't make the 15/17 combo work with the standard length chain or with an additional 2 links.

I've been going all season so far (about 8 good rides) with the half-link from this chain repair kit:
https://www.denniskirk.com/parts-unlimited/520-standard-chain-repair-kit.p113131.prd/113131.sku

I also carry the rest of this chain repair kit, an extra eBay half-link and two or three extra master links.

I started out this year with a non o-ring chain and the half-link, but I started getting worried that the chain would break because of how much it was stretching every ride. So for the last couple rides I've been using the same half-link with my original o-ring chain and it's working fine so far.

I also have a Tsubaki non o-ring chain and half-link that I'll install if the current setup starts looking like it's going to fail.

All this anxiety over whether my chain will make it through the day has me thinking about doing something else for next year. I might swap the sprockets in the chain case to get the gearing I want, or just live with the lower gearing of the stock setup without a half-link.

Thanks for the info, maybe I'll try it for the short term to get a feel for that reduction. After just toasting my side panel, case cover, bearings and tailbone due to a snow covered stump I would like to avoid other causes of anxiety!

So far I tried stock 13/17 & 17/20 (1.54) and 12/17 & 20/17 (1.2). Stock left me over revved in 3rd and not pulling 4th in the deep The other setup was good but I wanted a little more reduction to help get into 3rd gear in deep/steep. Hence the 15/17 & 17/20 (1.33) that sounds like it would be the best of both worlds (for me any way...).

I've used the Tsubaki non oring with their half link kit. Worked fine on the 500 ! Seems to be nice and strong !

Just ordered some. Thanks for the link. Ha HA. That should let me run a 13T on my 300.

Summitboy, can you post a link to the tsubaki link you had success with? All the images from searching for their 1/2 links shows a regular clip style master link or no image. I just wan't to make sure I order the right thing up.

Sorry if this is a double post - I'm new on here and not very familiar with forums...

Motogeek - what bike did/do you have the half link on? Just wondering how much power that link is handling.

I ran a 15 tooth primary on a 17 YZ450Fx with a 137 sx timbersled and it worked really well. It fit the torc curve of the bike well. Had to use a half link to make the chain work. Rode it for 2 seasons. About 30 to 40 rides total. FYI...

I see they also have an HD version of the kit. Was it just the standard kit that you have been using?
