Bend whatever you need to make the switch work better then smear it all with dielectric grease and you will never have a problem again.

Again be very careful of small parts under spring pressure.

That is good general advice, but I don't believe Adjuster owns an RX3.

Yes, the switch can easily get stalled in a 'dead' position. In fact, my light switch used to stall in a 'dead' position. Then the low beam would not work. Finally, the light switch would not work for either beam in any position.

I took the switch apart, and it is not designed in such a way so it can be repaired. Therefore, I cleaned the switch, and applied dielectric grease to the contacts, but it was dead.

I contacted CSC, and they sent me a new switch. CSC has excellent customer service, which is unparalleled in the world of Chinese motorcycles, and excellent for bikes from any country of origin.

I removed the slide switch which controls the headlights from the old switchgear, and I installed a nice toggle switch, instead. I will post a thread on that repair this evening, and leave a link in this thread.

Hey all, had something odd happen. Came back from riding with the Western US tour. Which was awesome. Was glad to have met a bunch of you owners. Anyhow, was time to change the oil. When replacing the 8mm nuts on the oil filter cover I finger threaded first one side on a little then the other side. Then fingered tightend them down to snug. I next used my 8mm t-handle wrench to just add a little more snugness to make sure no leaks. One side snugged down fine the other just kept spinning and spinning. So I got my vice grips out and got a hold of the nut and pulled while backing off, hoping to get the nut to catch. No luck. However the post finally unscrewed and I was able to then cut the nut off. Oddly the first couple of threads are intact, but several of the next few threads are stripped on the post. Has me scratching my head what happened since I hand threaded them. Oh well will call CSC in the morning and hope they have the post screw I need in stock.

As long as someone doesn't overtighten, two flange head bolts would work as well, maybe better. However, a lot of people would overtighten the bolts, and strip the threads in the crankase, so studs were installed by the designer.

I repaired the headlight slider switch on my Zongshen RX3 switchgear. Here is a link to a thread which describes how I did it.

Spud, that's a great fix. The main objective of my initial post was to alert RX3 owners to the dead spot issue so they aren't riding around with their headlight off. I had planned to live with the switch while checking to make sure I had not nudged it to the dead spot. Your post suggests that more problems may be ahead for my switch. I do hope CSC is looking into a better fix as well.

NoVa I don't own an RX3 like you guys but all these switches on any motorcycle of any manufacturer pretty much work exactly the same. Some are going to be built to better quality and tolerances then others but the basic internal mechanics and functions are the same. Just open your switch up and have a look around. I bet you will be able to easily tweak it to work much better. Its all springs and ball bearings. Each ball bearing is a detent for the different functions and sometimes they are not under enough spring pressure to make a good and positive detent and connection.

Again a warning. Lots of small parts under spring pressure. Make sure you have a good hold on everything so you don't lose any parts. Its even a good idea to disassemble in a box or under a towel to keep parts from shooting over into the neighbors yard never to be found again.

Once again, that is very good general advice. However, I examined this particular component thoroughly, and I could not find any effective way to fix or adjust it. Therefore, I cleaned it, applied dielectric grease, and reassembled it. However, it still would not work. If anyone finds a way to fix/adjust this switch, I hope they will post the information.

The rest of the components in this particular switch, and the switchgear on the right handlebar, are very nice. However, this particular component is designed in such a way that it is extremely difficult, or impossible to fix/adjust, and any such efforts which are successful probably wouldn't last very long.

Indeed, I like my RX3 very much. However, I am sure this problem will arise again, so I presented the information as a service to my fellow RX3 owners. As always, the customer service I received from CSC was superb, and I'm sure this minor issue will be resolved.

[SpudRider]

Many people have ridden thousands of miles on the Zongshen RX3; it has proven itself to be a reliable, and fun motorcycle. In fact, the fellows from CSC are currently making a group ride of 5,000 miles across the western United States.

The RX3 has an excellent engine, cooling system, transmission, clutch, et cetera. Every motorcycle has a minor fault or two. I think it is an excellent testimony to the quality of the Zongshen RX3 that the switch for the high/low beam is the only real problem I have found with the bike after riding it for 6,000 miles. I'm sure this minor problem will be easily, and quickly resolved.

These forums are here to help the community of Chinese motorcycle owners. Whenever we note a potential problem, we will let you know about it, so you can be prepared.

Does the head light have adjustment up and down? Mine seems to be pointing down too much when riding at night. I looked and don't see an adjustment screw any where around the headlight. Don't have manual or dvd with me just now as I'm at work and ,well lazy ,easier to ask you guys as I forget about it when home or till riding again at night, Ya know what I mean, thanks rj

You just loosen the 2 Allen headed screws on each side of the headlight, and tilt it where you want it, and tighten back up.... and Done

No problem...sometimes it's hardest to see when it's right in front of you... (at my age anyway ....now where are my reading glasses..... )

[detours]

Don't feel bad. It stumped me too! I ended up pointing it all the way up. When I aimed at a wall, that seemed to be the right height.
