Hi Ken,
First, check all of the electrical connections.
Since this is happening as you get further into the timing advance
curve, I suppose that the advance mechanism could be malfunctioning. You
probably ought to have a look at it - clean, lube, replace the two tiny
little springs as necessary - and see what that does. Instead of the
stock springs of different lengths, some guys (namely Mark Etheridge)
recommend two of the shorter springs, I think. I believe the rationale
is that it works better with the fuels we use today???
Also, it may be that problems one and two are related by the coil or a
faulty condensor. I would start by replacing the condensor and see what
happens, after that, I would address the coil.
As for a loom, unless you are changing the location of the fuse box, I
think the MG Cycle loom is the best for the money I've seen. Sure, you
could make your own - but I think that would end up much more expensive
unless you resorted to all black and red wire! :>
Best of luck.

Greetings to all, I have recently acquired two Moto Guzzis, a 1971 Ambassador still slumbering and a pretty nice 1973 Eldorado with quasi police setup; floorboards, LAPD side stand, a trunk box. I have lusted after the MG Vtwins since my Air Force days, but didn't scratch that itch until about a month ago. I am having midrange acceleration issues with the Eldorado that I can't seem to conquer. I have timed it, at idle and at speed according to the manual, removed, inspected, cleaned, remounted the VHB30s and balanced them at idle. The previous owner had reinstalled the accelerator pump pistons incorrectly and after I corrected that, the bike ran much better. The bike starts right up when cold, most of the time- about 80 degree F where I am- and runs well through the gears as long as I don't try to blip the throttle or accelerate past 3200 to 3500 RPM. If the throttles are opened too much or pushed beyond the 3500 RPM "limit" the engine gasps bogs down, obviously either fuel starved or, perhaps, unable to advance the distributor far enough to provide spark. It seems like fuel starvation, but I am, obviously, not sure. An MG mechanic friend says there may be an issue with fuel tank venting, so I'll check that, as well. Any advice would be welcomed. Issue # 2 is electrical. Seems the coil/distributor circuit loses juice or has a voltage loss at times. Could this be due to the relay going to ground? The charging system works , as the starter always cranks fine and seems to have plenty of current for the start circuit, but, on testing, at times, there will be no current to the distributor. I will be rewiring the bike with an MG Cycle loom in the near future, unless someone has a better suggestion other than building my own loom. Comments on this issue are welcome as well. Thanks to everyone in advance. I have enjoyed the posts I've been receiving and hope to contribute someday. Ken Smith San Rafael, CA |
