The Zongshen TT 250 is Coming

[Mudflap]

It's not a roller chain, more like a mini multiplate cam chain. I'm hoping it's the same as the TT uses so I can order one from CSC when they get the parts stock. In the mean time I bought a new non-balance shaft Lifan engine and will fix the old one when I find the parts. Can't complain too much about a little 200cc engine going 50,000+ trouble free miles.

I saw a great picture of a counter-balanced motor with the right side cover off here somewhere on this forum. Can't find it now...

It showed the crank to cc connection and the chain to the oil pump.

Anyone remember the thread or have that pic?

Cheers!

Can't complain at all! Regarding the balance shaft motor, a few years back here one of our past active members, WildAlaskan, had an old Lifan GY200 with a balance shaft motor and he beat the holy snot out of that thing on a regular basis! Obviously passes the durability test.
These motors are so small and throw so little inertia, it's not like we're comparing the mammoth Harley Davidson counter balanced motor to the non-balanced motor.

I saw the TT in person today as I'm in LA for work. I wouldn't have any regrets ordering for the price they are asking. They made some improvements for the production run and having the warranty plus all parts in stock from CSC will mean sound piece of mind vs. the other options.

It looks like a very easy bike to maintain as well.

Indeed, CSC has specified a lot of nice improvements for the TT250. Here is a quote from the CSC Blog.

http://californiascooterco.com/blog/?p=19601

...We’re incorporating quite a few upgrades on our TT250 bikes. There’s always a chance some of these features (above and beyond the standard configuration) won’t make it into the final version, but here’s where we are right now on the upgrades beyond what we’ve already described:

Our TT250 will have adjustable damping front forks.
The frame color will be satin (rather than gloss) black.
Our bike will incorporate the same left and right handlebar switchgear as the RX3 (these are higher quality switches than those usually provided on these bikes).
Our bikes will have a satin silver finish on the handlebars.
Our bikes will have the RX3 rear view mirrors.
Our bikes will have braided stainless steel brake lines for both the front and rear brakes.
Our bikes will have anodized fork caps.
Our bikes will have wheels dynamically balanced from the factory.
Our bikes will include several quality improvements that most folks will never see (that’s because of minor issues we saw on the four prototypes we’ve been testing; we’re addressing these things so you won’t have to).

It’s taken us a bit of back-and-forth with the factory to get to the above changes and we’re pleased with where we are. The Internet being what it is, I have no doubt some folks will say, “can’t you get this?” or “can’t you get that?” If it’s not on that list (along with the other features we’ve previously mentioned on this bike, like the inverted forks, the 300-watt stator, and the handle-bar-mounted accessories switches), the short answer is no. The TT250 is available in red, black, and white...

In addition, the bikes are manufactured by Zongshen, which has a deserved reputation for superior quality of manufacture.

Spud? or anyone else? Anyone recieved an explanation from csc as to why the tt250 is 20 to 30 lbs heavier than the hawk or bashan or indeed any of the similar bikes of this type?

I doubt very much the CSC TT250 is heavier. The Chinese are not noted for their accuracy with specified curb weights. I'm betting CSC is merely reporting a more accurate weight figure than the others.

Here's the tutorial I've been waiting for.

TT250 Valve Adjustment

Looks way easier than the RX-3.

hardest part of that is getting to it (removing seat and tank)

Holding the adjuster still while tightening the nut can be a bit tricky. Rather than marking it up with pliers, I use a #2 Robertson wood screw (square head to my US friends), and screw it into a Marrette electrical connector. It makes the perfect valve adjustment tool.

I fabricated the same tool, and I use that tool when adjusting the valve lash on my Zongshen Sierra (ZS200GY-2).

I have searched several large chain hardware and independent hardware stores in my area and cannot find "ANYONE" who stocks, or has even heard, of a Robertson wood screw. I have a call into Fastenal Fasteners currently and I'm waiting for a return call.
Do you use a flathead, oval head or round head Robertson, and what length do you recommend?
Thanks for any help you can suggest.

Ask for a square drive screw, #2 size. It will most likely be a wood screw.

I am wondering what a "Marrette electrical connector" is. Is that what I call a wire nut?
Edit: I asked Google - yes, it is a twist-on wire connector that I call a wire nut.
