I am on the hunt for an aftermarket shock absorber. Is anyone else interested in upgrading the stock shock absorber?

Spud, I'm sure I'll be looking to upgrade the shock when I get back. Suspension is a pet peeve of mine. Is the schrader valve a high pressure model like on an acft or a regular car type? Can you post a picture? If it's harnessing 300+ psi, I'm thinking it's an acft type.

Good for you, Veteran. This morning I talked to Ryan and Rich at CSC regarding the possibilities for an aftermarket shock absorber.

I haven't yet removed the shock, or removed the saddle to inspect the schrader valve. However, I might make some progress in that area tomorrow. In the meanwhile, here is an image of the RX3 shock from the Taobao website.

Gave a new meaning to raining cats and dogs.

The indicator disappeared while I was cruising on the same gear. I think it's water-related. Have to pray for another storm to test it again. BTW, thank you for the feedback.

On another case, the side panniers are definitely not waterproof. Waters leaked in from the same storm, but luckily for the left pannier, I put my stuff inside my Kriega US10 (didn't strap it at the back seat, because I was heading to an urban area with theft cases).

But for the right pannier, my tool roll was damp, and there were ponds of water inside it that dripped after I opened the pannier to check my stuff.

Tourfella perhaps? Checked TaoBao, but thinking of ordering racks only, to save up some courier fees.

Thanks for posting the update from Malaysia. We don't get monsoon rains in the United States. I'm sure you are testing the waterproof features of all parts of your motorcycle, not just the digital dashboard and luggage. If everything else is running well, I think you are proving the water-worthiness of the Zongshen RX3.

Reading In the CSC Baja blog about the bloke who lost his counter shaft sprocket nut I was a little surprised.

Not by the loss of the nut, but the fact that it was a nut and not a bolt.

Though I know the CSC RX3 has a number of upgrades / differences to the Honley RX3 (UK), I thought the engines were exactly the same.

This appears to not be the case

I'm failing to visualize how a bolt would hold your sprocket on. Can you post of pic of your installed sprocket for us?

Here you go

The last time I had a bike with an adjustable rear shock was getting on for 25 years ago. If I remember correctly the bike manual had a table to refer to for setting it correctly.

If possible, could someone do an "Idiots Guide" that would be great

Or I will be stuck with doing months of something similar to this

My Honda CRF250X also uses a bolt to attach the counter shaft sprocket.

Interesting. I figured it would use two 8mm diameter bolts and a retainer.

You are correct. I just checked, and my RX3 uses a nut to hold the counter shaft sprocket.

The shock valve of the RX3 is definitely a high pressure valve. It is not a schrader valve such as is employed in motorcycle inner tubes. I was in error to describe this valve as a schrader valve.

That hadn't occurred to me, but it makes perfect sense that a Schrader would only be capable of 100psi or so. A quick search has not revealed the actual tolerance of a typical Schrader, but I have found several warnings against using a Schrader in a high-pressure application, like a shock.
