I spoke to Steve earlier. He said it was an H4. I went out and bought a PIAA H4 that I will attempt to install this afternoon.

Here are reasons why.

Immediate wind with heat. Radiators take a while to heat up. Instant heat leads to exhaust.
Right side has three possible locations that would have an easy leak.
1) header to muffler joint. There is a fiber material clamping and sealing the two steel pieces. Easy to damage (or be missing)
2) O2 sensor. Loose, missing, cracked weld
3) Header to head. Loose clamp or damaged or missing gasket. Outlet is faced to right side and wind speed would blow to right side.

Having ridden in 40-70F temps so far 1 and 2 up there is no noticeable heat on right leg for either of us. Wearing jeans or work pants.

Good luck in finding the source of heat.

Someone can help find this thing? I have not know much about motors and motorcycles.
Problem: right radiator is venting more and heater than the left.

I have to ask this; are you wearing pants or shorts when you ride? (No one laugh please) , if you're wearing shorts, you'd notice the heat from that side more than you would if you're wearing pants. Like someones said earlier; if it's an immediate problem after starting, I'd suspect an exhaust leak. If it's after the motor's warm, then perhaps radiator fan. Those should be the only two sources of heat unless you've got an internal motor problem which would manifest itself by metalic noises and discoloration of the engine case or cyl.

Initial dyno test.
Inertial type at rear wheel.
16.60hp @ 8230 rpm
12.47ft/lb torque @ 5950 rpm

I will try and get some graphs loaded.

Just looking at that video my first thought is the direction of the fan is going to throw heat either left or right.

Excellent! H4 is good. I have several H4 upgrades from previous experiences. I've yet to hear any complaints about poor headlight performance, but I can't tolerate ineffective lighting and will definitely come up with a plethora of solutions. 300 watts is a lot to play with, especially since the Cyclone is all LED, which draws almost nothing.

Is the stock 35/35 an HID by chance? Pictures look like a projector lamp. Either would be a blessing. Both would be AWESOME.

To me, that's a good number at the wheel. I bet the factory specs are at the crank.

To put that in perspective, CG200 motors are rated for around 17hp at the crank; much lower at the wheel.

Not an HID. Just a really dim light. I bought my PIAA at Cycle Gear, where they had an LED conversion kit. I didn't hold much hope of that working. I will wait and get a ZS LED light at some point.

Miqueas, Very good video. The only thing I thought of is seeing your overflow bottle seems to have a lot of coolant in it. Maybe it was over filled from the factory and it's burping out the excess now? I couldn't see any marks where it's suppose to be filled to so maybe someone else can check theirs and see where it's suppose to be???? rj

What is a ZS LED?

I'll wire up a relay and run one of the H4 60/55 bulbs I already have. That will keep it legal.

If more light is needed I have 7-inch round headlight housings that will take Hella ECE composites and H4s on a light bar. Not legal on cars, but legal on motorcycles. Maybe a bit heavy, but they give awesome light.

Miqueas, is the temperature normal on the dash? This is probably a long shot, but I wonder if coolant isn't flowing correctly from right to left ... air in the lines could potentially block the flow. You could try to 'burp' the coolant lines following the procedure at the end of this tutorial.

Also, do you have a warranty on your bike? Maybe the shop would look at it for you.

Zongshen. I work in aviation. We abbreviate everything.

Perhaps CSC specified an H4 bulb, but the stock headlight bulb in the Zongshen RX3 is an HS1 bulb. HS1 bulbs are rated at 35W/35 for a standard bulb. Since the headlight output of the RX3 is fairly poor, I assume my RX3 has the 35W/35 HS1 bulb.

The H4 and HS1 bulbs have the same connector configuration. However, one of the connectors is a different thickness. Therefore, you can substitute an H4 bulb for an HS1 bulb, but not the other way around.

http://en.wikipedia.org/wiki/User:KDS4444/HS1_bulb

I plan to install an H4 bulb in my RX3 headlight, since the H4 bulbs have more power, and the RX3 alternator generates enough electricity to support the brighter H4 bulb.
