I recently repaired a nasty fault with the XLCH. The fault
was "Severe misfire of the rear cylinder, front one OK".
Timing? How can that be, it is mechanical, (no electronics
apart from a condenser). I replaced the condenser and no difference. A
compression test proved OK, in fact the rear piston was slightly
higher than the front one. Swapping the plug leads/plugs over made no
difference, then a careful look at the contact breaker cam revealed
The contact breaker cam had spun around 180 degrees, not affecting
the front cylinder but firing the rear 40 degrees too far retarded.
Removal, cleaning and replacing affected a cure.
Replacing the thrust bearing on a 1200 Sportster fitted
with a "Dry Clutch".
Remove the oil from the primary chain case. Disassemble the clutch
actuator and remove the clutch puller bolt. Remove the centre circlip
from the clutch housing and remove the old bearing/bits of bearing. If
the bearing has broken, use a cheap deep socket of the appropriate
size and an open vice to knock the old bearing housing out. Snap-on
Tools tend to be too expensive to replace! Fit the new bearing on the
old shaft and press into the housing, refitting is the reverse
procedure. Use Hylomar Blue to fit the new gasket, it doesn't go hard
and crack like the red stuff. If it's good enough for Rolls Royce it's
good enough for HD.
(I heard somewhere that HD stands for "Hundred Dollars" as that is
the average cost of spare parts!)
HD use a different charging system to Lucas in the UK. The
dynamo with the Lucas system puts current on the field winding to
excite the armature to produce power. HD short circuit the field
windings negative lead to ground and use the latent magnetism in the
iron core to produce a small current that increases the magnetic
strength which in turn increases the current output of the dynamo.
Regulation is by way of removing the short circuit when the battery
voltage reaches 14Volts or so. Crude but effective I think and HD
regulators cost around £80 which is about $100.

|Travel - I like to travel. I have never felt the need to
travel abroad, well I did go to the Isle of Wight Festival back in
1970 and watched Jimmy Hendrix live. I remember some of it! When I
have seen the UK I will travel to a country that is very green and not
far from Wales. Wonderful countryside and friendly people, oh yes and
the Black Stuff.

and is very interesting. Miss Marples to Hancock's Half Hour.
Wonderful. I don't own a TV as they take up too much time, a radio
allows both enjoyment and entertainment whist doing other things like
research or household tasks like the washing up!
