Didn't expect that many replies ...
Just to start from the beginning:
when i got here to China once in a while i ran into one of these Changs and tried to get more info about them. Due to the ancient look and also to the fact that they are built based on Beemer-drawings a lot of foreigners here are interested to ride those bikes.
Some workshops around here to restore them and sell them to mostly expatriates working in China - alone here in Beijing are more than 10 shops doing Chang Jinag business.
The clue behind is to find THE shop which is reliable, reasonable priced, up to date aso
My first ride was my 32 hp tan coloured "Rommel Bobber" which i bought right from the restauration shop. Loved quiet a lot but started to customize 3 months after i got coz i didn't want to ride around like all the other foreigners ...
See pics of the different stages of my first sidecar:
first update was to add crosscountry rubbers to give it a more rugged look
first "mild" customizing was to cut the tailfender and add a sparto taillight
i ran that sidecar for about 5.000 km - sold it to a guy in Germany - shipped and now it is running over there without any problems
my second ride was the black solo-chang with the smaller flathead engine with 24 hp
you find some pics of the build-up on the thread of billdozer - someone of you guys posted my pics there ...
was the mockup stage when i tried to fit all the imported parts like taillight, footboards, aso
the black ride has now also about 3.000 km on the clock WITHOUT ANY PROBLEMS except a blown fuse ...
since a couple of months i ran the ride on 16 inch rims - i was always hot to be the first guy in WHOLE CHINA to run a changjiang on HD rims with those nice rubbers
was really though to get those 16 inchers on the chang - lots of trial and error and all parts like spokes, rims - even tyres had to be brought in by myself in suitcase or imported from the US
since more than 1 year i owned the red chang also - again with the flathead engine and also changed the rubbers to 16 inchers and some other changes
the fenders are sold to a guy in the us - teh sparto is the one i initially had on my desert bobber
now the parking lot gets more and more stuffed coz i already planned for another bike - once more a "Desert Rat" but also solo-bike
