Cam gear adjustment
Posted: Mon Aug 31, 2015 2:21 pm
Hello,
Despite reading a lot of posts on this message board I've gone ahead and bought a new Classic 500, one of the limited edition ones. I don't yet have it as it is being registered tomorrow, but I have nevertheless already ordered and received from our host (excellent service!)a few service items and the workshop manual. I must say the latter made me laugh; what other manual would include a chapter called "Blow Up Charts"? Also some of the pages are out of order and there's an odd bit of text referring to cam gear adjustment in amongst the section on rear chain adjustment (I think...). It is this that I wondered about. According to the manual the gears are supposed to be checked and adjusted at 500 miles, yet there is no reference to this in the service schedule in the manual. Does anyone know what the position is on this?
I must say I'd prefer to service the bike myself, but I fear that this would be unwise whilst it is under warranty, though I'll change the oil every 1,000 miles anyway, like I do on my 1954 Tiger 100.
Having read various posts on the EFI system I think I'll wait until I've run it in before deciding what, if anything, to do re tuning. The system seems basic, though it is not entirely dissimilar to the Motronic system on the oilhead BMWs I have owned, not least in that they too had a manual "choke" for cold starting, though actually all it did was hold open the throttle butterflies a pre-determinjed amount. Also, neither of my Beemers has an O2 sensor, so they ran permanently open loop, the mixture at the lower end being adjusted by a CO pot. Adfjustment of the TPS voltage to one recommended by the various BMW forums allowed me to eliminate surging. Others amy be interested to know that DWR, the dealer from whom I'm buying the RE, has sent an ECU to Germany to have it decoded. His main business is tuning ECUs for (mainly) Jap and Italian race reps, for which he has a dyno. So, whether I end up "flashing" the ECU or getting a Power Commander I can't yet say. Maybe it'll run OK in open loop mode anyway. I'll see.
Carole Nash database doesn't actaully yet recognise the Limited Edition" despatch version and they wouldn't
give me a discount for the security afforded by the camoflage paint scheme either...most unreasonable, I thought since if you can't see it you can't nick it....
Anyway, must go now to finish making a replica rifle and mounting (Enfield of course).
