Help! Help! Help! While dealing with the float bowl overflow issue of my 1983 R65 - riding along at 45mph - engine cut out, tach needle stuck at 4000rpm - with dead engine. Coasted to stop, carb NOT overflowing. Tach needle casually returned to 0. Waited a few minutes, pressed starter, engine spun, coughed, started right up. What the? Rode short distance home engine running smooth and even. Inspected under gas tank, observed nice long crack in original grey coil both plug wires attach to. Ordered new coil from BMW dealer, gave year of R65, described coil needed. Received single 6 volt cylindrical coil from dealer. What the?? Checked parts schematic online, only coil shown is coil as sent, nothing like what is on my bike. What the??? Is original coil available or was Dyna Coil used as original no longer available? Do engine cut out symptoms above indicate specific electrical issue? Would cracked coil produce symptom? Anyone out there have similar experience? Bike is forlorn sitting in garage...
