In this day and age of superb electronics and FI would one dare to ask if there is a kick starter kit available for the RX3 ? rj

Indeed, I understand the entire engine expands as the engine heats. However, I still believe the exhaust valves must certainly heat up more than the intake valves. The intake valves are cooled by the incoming fuel/air mixture on every intake stroke, whereas the exhaust valves are always heated by the expelled gas on the exhaust stroke.

Many of these other bikes have a kick starter, so the parts are certainly available. However, the frame of the Zongshen RX3 is different from these other motorcycles, so sufficient clearance for operation of the kick starter might not be present on the RX3. We won't know until after we receive our bikes. If sufficient clearance is present for a kick starter, one would also need to install a different, right crankcase cover, in addition to the kick starter parts.

I wonder what the valve lash specifications are for the Gas Gas EC Cami 250, and the AJP PR5?
Both of these bike employ the same, NC250 engine as the Zongshen RX3.

The SSR 250R is another Chinese bike which employs the Zongshen NC250 engine. Zongshen only supplies the engine for the SSR SR250R. This engine does have a kick starter.
The SSR SR250R is currently being sold in the United States by at least two online vendors. http://tboltusa.com/store/ssr-sr250r...ike-p-969.html http://gokartsusa.com/SSR-250R-5-Spe...loy-Frame.aspx You can find more photographs of the SSR SR250R at the SSR.com website. http://ssr250.com/

Asiawing uses the engine in a few of their bikes (but I believe one of these bikes they OEM for SSR)

Of the four bikes you listed, it appears the NC250 and DT250W are the two models which employ the Zongshen NC250 engine.

Cam chain adjuster info
Spud (or anyone) know if the cam chain adjuster is automatic or manual? Also, what are valve adjustment intervals on the RX-3?
Thats definitely a small valve clearance...about 1/2 what most intake specs are, and almost 1/3 most exhaust valve specs. This may be a reflection of the better steel used in the valve seats (and valves themselves), which is not wearing as much as in the past. maybe? |

Courtesy of MotoJ, the owner's manual for the Zongshen RX3 is available for download from this website. http://www.chinariders.net/files/Zon...ers_manual.pdf The links to this manual, the Delphi EFI manual, the CSC maintenance tutorials, and other interesting threads are all included in the Zongshen RX3 sticky thread, which is pinned to the top of this Dual Sport Forum. http://www.chinariders.net/showthread.php?t=14228 According to Table 2-2, on page 9 of the RX3 owner's manual, the first valve clearance check is scheduled for 1,000 kms (600 miles), and subsequent, valve clearance checks are scheduled every additional 4,000 kms (2,500 miles). I'm not saying the valve lash specifications are necessarily wrong, but I am very surprised the exhaust valve lash has such a low value.

Once again, I wonder what Gas Gas and AJP are specifying for the valve clearances, and the valve adjustment schedule.

Apparently, CSC waited until 8,000 miles to check the valve lash on their red bike which underwent emissions testing. The Silk Road Rider traveled from the east coast of China to Istanbul, and I doubt he checked, let alone adjusted the valve lash during the entire trip. If I may ask, where did you find the AJP maintenance schedule? Can you please provide a link?
