God willing, I plan to pick up the bike at the loading dock, and assemble it tomorrow morning. With any luck, I should have insurance and a license plate shortly thereafter. If all goes well, I plan to go for a ride, and take some photographs. Needless to say, I will certainly post my impressions.

Hope you get a good nights sleep tonight Spud. I'd be awake with anticipation all night. Mine may ship this week. Nothing definite yet other then it's paid for and magnificent ORANGE too, rj

You mention getting a lot of "wind " on the right side as soon as you start it. Is the right side radiator fan coming on as soon as you start it? As for the "vapor" are you loosing coolant from a loose radiator cap or hose clamp ? Just thinking out loud here. Let us know what you find.

Hi thanks for the reply, no holes, no loosing colant I guess, I haven't seen nothing.
As soon as I start, no. The first time was like that. I have checked right now and is engine ON but no vents working, which is OK.

When I say vapor, I didn't mean like smoke or something visible. I was refering like a blowing (vent, radiator)

My question is why the right vent is warmer and venting more than the left one?

Today I had it checked in the Zongshen service center. And they found nothing.

Thanks for the answer. I hope you can ride it soon.

Anyone else is having this situation? I would like a explanation so I can understand this

Even with this, great bike.

I have not heard of anyone else reporting this phenomenon. Therefore, I might be wrong.

Since the hot coolant first enters the right radiator, a greater amount of heat might be removed in the right radiator before the coolant moves to the left radiator.

First fill up.
2.685 gallons at 161.0 miles = 59.96mpg 75% highways 55-65mph 50% 2 up

Flashing Empty on gauge at 143.3 miles.

Based on this I think an extra 50 miles range once Empty flashes without any issues. and almost double to full empty but with fuel pump overheating issues.

Fuel pump overheating issues? Care to explain?

Fuel pumps need to be immersed in fuel to not overheat and fail.

Total volume of fuel tank is not useable without damaging fuel pump.

So 4.2 gallon tank
~3.3 useable volume
~2.5 till Empty flashes

So when the idiot light starts flashing then you still have about 40% total volume of fuel in the tank. A carbureted bike has the advantage here. It can use 99.9% of its fuel before there is any issue. At 100% it stops running.

I guess I will have to drain tank and use scope while adding fuel to find actual volume that immerses pump completely.

I kinda doubt engineers would expect 25% of fuel capacity would be necessary just to keep the fuel pump cool. One reason I jumped on the Cyclone was its tank capacity as I do not like risking the hazards of extra cans and bottles, pouring, filtering, etc. If the stock fuel pump precludes using most of that capacity I'll simply install an inline aftermarket pump and be done with it, but I won't be happy.

oldqwerty, That's a good idea. Would you disconnect the original and just leave it in the tank? Also would you use a hi pressure or lo pressure inline pump? I looked on the bay auction sight and they show both but I don't know which would work on the RX3? prices from $14 on up. rj

This is exactly what the engineers expect. 25% of capacity to cool fuel pump.

I got my tag today for the RX3. The lady behind the counter struggled a bit trying to find the information for it, but luckily the packet Sara sent from CSC contained everything that she needed. In and out within 10 minutes with my new tag! Now I just wish I had the bike! LOL

I've had my RX-3 for a couple of days now and have completed its first oil change. I was planning a local off-road trip and it occurred to me that I had not seen anything about the exhaust having a spark arrestor. Can anyone shed some light on whether this bike is legal for off-road?

That's an excellent question because for me, most of my riding will be on USFS back-roads. I saw the other response about approved cans have "USFS approved" stamped on them and I've seen that myself, but I also know my BMW F650GS doesn't have that stamped on either can too and I suspect none of the other BMW's that ride the millions of miles of adventure trails don't either, (I could be wrong on that though).

Now that you've brought it up, I'm going to be paranoid. It's not like "back-in-the-day" when people rode 2 stroke dirt bikes with crappy stock or home-made exhausts and sparks flying out the POS pipe they had on and "possibly" starting forest fires, but there are regulations on the books now and I don't want to end up paying a multi-thousand dollar fine because Ranger Rick is over-enthusiastic either. I know the bike isn't going to burn down the west coast, but anti-biker, anti-motor- tree huggers, (of which there are aplenty around here), will look for any reason to get our fire-roads shut down from ALL motor vehicles. Dag.....I guess I better figure this out.

Good for you.

I spent the better part of Tuesday assembling my Zongshen RX3, registering the bike at the DMV, getting a license plate, and buying insurance. I finally went for a forty-mile ride on pavement, and the bike performed very well.

The U.S. Delphi EFI system performed smoothly, without any flaws. The 6-speed transmission is very smooth, and trouble-free. The bike has a nice clutch, and the 14T/44T sprocket combination is ideally geared for the pavement. The Siemens digital display and analog tachometer are excellent; I really like the gear indicator. The exhaust is quiet, but it has a nice throaty sound. Both brakes performed well, as did the suspension. I road a bit on the interstate highway, and the windshield did a very good job isolating me from the wind. It was a short ride, but I found the seat comfortable. I also like the upright riding position. The bike feels light and is easy to control during low speed maneuvers. The NC250/ZS177MM engine makes good power for a 250cc engine. The LED turn signals and tail light are very nice. The switchgear is also very nice. The Zongshen RX3 is a lot of fun to ride.

I like the saddle, but I dislike the seat cover; it is not very durable. I am going to cover the saddle with some stronger fabric. The headlight casts a nice pattern, but the 35W/35 bulb is too dim. I plan to install a 55W/60 bulb tomorrow, but I have already ordered the upgraded LED headlight.

I didn't take any photographs today. However, I am going to test the stock tires and suspension with some off road riding tomorrow, and I will take some photos at that time.
