As I reported Precious´ rattle got louder during the last 2000 kms and I was concerned about the reason. After a 270 km-trip to a countrywide recommended RE-garage in northern Bavaria, the shop owner Flo Nytz, who is the only mechanic too, diagnosed the primary chain to be too loose and with a proper adjustment he not only removed a big part of unspecified mechanical noise, but also reduced load change play a lot! I got a brand new B5 from Flo for getting about while mine was maintained, so I had an exellent oportunity to compare. With the rumbling of the loose chain suddenly eliminated there is only the valve clattering left. It´s a little louder after 14´kms, compared to the new engine, but perfectly acceptable now.
Btw, I was surprised that the B5 has a different handlebar: a little more narrow, the ends bend down a little bit. It´s very comfortable, but not yet available in Germany - as well as all other B5 parts
I really enjoyed talking to someone who not only seems to have a lot of knowledge and experience, but just makes time to get things straigt. In case other European RE-rider happen to get to northern Bavaria, here´s the link:
http://www.enfield-motors.de/joomla16/The drive sprocket´s shaft was not tight anymore, so the seal was replaced. The plastic swingarm bearings, that showed light play were replaced by the old rubber version that will work better, according to Flo.
In addition he mounted a spacer sleeve between the foot peg mounts underneath the engine to prevent, in case of a laydown to the left side, the nut that holds the peg to be pushed into the engine case.
Another tip: mount the rear axis vice versa. Every time it´s tightened it works itself into the mounting on the ride side. On the left side there is only the swingarm that seems to be more stable.
Modified and tenderly cared about, Precious ran tame as a lamb back home the next day, under white blue, postcard-like Bavarian sky and 25°C. Almost too good to be true
