The Zongshen TT 250 is Coming

[SpudRider]

Joe,

Somebody inquired about the bore and stroke for the engine of the TT Special. Do you have those figures?

Now, before all the trolls get their nostrils in a twist, the first comment was made in jest. Visualize me holding up a sarcasm sign. And the second statement was offered figuratively (not literally). If you own either a CSC-150 or a CSC-250 and fire a .357 magnum into it, we will deny your warranty claim.

Darn, I was just getting out my AK and was looking for a CSC...

Weld,
What is the frequency of the valve adjustments on the CG pushrod, 2 valve engines? Mileage intervals?
I hope not the frequency of the RX-3 engine configurations.
What is the usual redline rev range of the CG engine configuration engines?
Approximate rev redline?
Thanks

Corven is also importing this bike to Argentina as the Corven Triax 250 R3. The main difference is the Corven bike has conventional forks, and the CSC bike has USD forks. Here are two videos from Argentina featuring this motorcycle.

Valves? Adjust 'em when they quit making noise, or it becomes difficult to start. IOW, not very often.

Redline? Who knows. I've never used a tach on one. If I had to guess, I'd say cruise between 5000-6000rpm, with a redline at 8000.

They rev, but not as freely as an engine with a cam that has a dedicated lobe for intake and exhaust. That's the trade-off for an anvil-simple engine.

Speaking of RPM's, What instruments are included on the dash of the Zongshen TT250 bike? Hopefully a speedometer! But what else?
Odometer?
Trip meter?
Fuel Gauge?
Tachometer? Redline Indicator?
Temperature Gauge?
Turn Signal Indicators?
Gear Position Indicator?
Headlight Indicator?
Readability of the Dash Information?

Can anyone post a photo of the complete TT250 dash layout?

[SpudRider]

Go to 0:48 in the first video, and 0:58 in the second video.

It appears the bike has the following information on the dashboard.

Speedometer with Redline Indication
Odometer
Trip Odometer
Fuel Gauge
Turn Signal Indicators
Neutral Indicator
High Beam Indicator

Of course, CSC has the definitive answers.

I adjust valves on my CG engines every 2000 miles. Only takes a few minutes on my bikes. Max horsepower on most CG engines is at 8000 RPM so there isn't much point in running it at higher RPMs although I've run 9000 RPM without a problem. Max torque is 6500 RPM. The tach on my Lifan 200 with CG engine shows a red line at 11,500 RPM but that's probably not correct.

I do, and I have many more. Bore x stroke are 66.5mm x 66.2mm, for an engine displacement of 229.92 cc. I was out on the TT Special today. The bike is a hoot. No one will be disappointed riding this motorcycle. Took it off road for a bit, too. Hard to believe I actually get paid for this.

Thanks for posting the engine specs, Joe.

While I have you here, we would like to invite you to participate in our Zongshen RC3 thread. If you have time, please do join the discussion at the following link. The RC3 is generating some interest among our members.

Oil filter information******
First off, does the TT250 cycle engine have an engine oil filter? And is the filter a disposable or reusable filter? Is the oil filter a screw on cartridge, a disposable paper filter, or a metal screen/filter that is reusable after removal and being cleaned? Is their more than one oil filter in the bike's oil filtering system? And where is the filter located on the engine? Is it easily accessible or is it necessary to remove parts of the body work or engine to remove and replace the filter?

[Weldangrind]

It'll be a washable oil screen, just like an XR200. It's one cap that you remove, which is followed by a spring and the screen. No covers in the way. Super simple.

It's located on the left side, adjacent to the shifter. Just put the bike on the side stand to drain the oil.

[Darkrider]

Its gonna be a tough fight deciding which bike to get lol...hopefully by the time i get out of school in '17 the TT will be available in Canada as well.

[Lee R]

I'm curious how much the TT weighs. Depending on the price I'll probably be on the pre-order list for one.
