New Zongshen RX3 (ZS250GY-3) Dual Sport

[katflap]

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

I am going to start adjusting the sag and spring preload today. I will post a thread on this topic, including the rebound damping adjustment, in a few days.

How do people like their CSC centerstands? Are the new springs holding up? Please check in, and let us know.

the new headlight ,has two separate 'l,e ,d ,least thats the way it appears ,,,one at the bottom and where the standard bulb was.

Oh btw ,,,the centerstrand is a huge disappointment ,,it is poorly designed and hangs down much too low ,,if i ever would go offroad i would surely get stuck, as it will catch on everything you go over...I'll see if i can get a picture ,but its sitting in the shed and its raining......

I like my center stand Spud. Spring seems to be holding up so far for the 3 days I've had it. It doesn't hang down any farther then it's mount which is on all RX3s whether you have the center stand mounted or not. Don't think I'll ever get into a bad situation with it as my single track dirt riding, log hopping days are well behind me. For my intended use of chain maintenance it should be fine. rj

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

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 ...

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

Thanks for the good report, Fish.

Thank you both for your feedback, gentlemen.

Today I started experimenting with the shock spring preload. Upon inspection, the RX3 shock absorber looks nice and beefy, with a large spring. After loosening the nut on the locking ring, I reduced the spring preload by moving the lock nut up the shock absorber. After three full turns, all of the preload was gone, and the spring was loose. Therefore, the spring preload on my bike, set at the factory, was at its minimum setting.

I tightened the spring preload back to the original setting, and added three more turns to increase the spring preload over the minimum setting. I went for a ride, and the shock performance was improved. However, I still need to add more spring preload before I find the optimum setting for my weight and preferred riding conditions.

I had to remove the battery and battery holder to gain enough access to loosen the nut on the locking ring of the shock. However, after that point, the rest of the process was very easy. I have a lot adjustment space available for the shock preload, so I am optimistic regarding the outcome. I continue to be impressed with the quality of this motorcycle.

I'd let you know, but I'm not having any luck getting my spring on. The tool I usually use isn't working for this application. I will say, that the spring mount and spring itself are much sturdier.

Thank you, Tony. You might want to get one of these Tusk Spring Pullers.

Tony, you can also insert a dime in between each coil of the spring. It will grow a considerable amount, allowing you to easily place the spring over the tangs. After it's in place, just pop the dimes out. Thin washers work as well.
