One of the guys in the club has a "modern" Einfeld. It needed a full rebuild after 6000 miles?
Yeah they copied it very exactly. No deviations or improvements. They only recently considered electronic ignition systems.
Normally one could get quite a few miles out of them, but you had to work on them all the time. The correct oil helped a lot too. We used to use Castrol motor oil (yeah the castor oil based stuff in our bikes). I am not sure if mineral oil lubes were ever good to use in the old Brit bikes.
I always wanted one of their diesel engine powered little motorcycles. But none ever made it out of India though.
I remember all the hassle I had with several Brit bikes I owned many years ago. The Royal Enfield Interceptor 750 was the worst of the bunch.
I remember Aurora being somewhat hit and miss on their engines. I had a couple of the Mills .075 engines I bought back in circa 1977 and they were both bad right out of the box. Then later around 1981, I bought a Taplin Twin copy and it worked great. That Taplin copy ran really well, one flick starting, never missed a beat. I regretted selling it. I have a Aurora 35 RC diesel engine but I have never tried running it yet.. So I don't know if it works or not so far.
Here is my Eastman Roadster which is a copy of the old Raiegh Deluxe Model One (or DL-1) first made under contract for the British Military in 1913 in India. They never changed the design or improved on it. it is still the same today as it was then. Pushrod brakes, no cables. Oh yeah, no instructions either. Now then the quality control was me, so technically the Indians didn't have anything to do with the assembly and fitting, I did.
This is how I recieved it. I had to really put it together myself. Now the pedals were assembled, but I needed to disassemble regrease and then reassemble the pedals too.
One of my favorite things about the bike was the inflation instructions on the tires:
It has a neat bell too.
