I started my bike five consecutive days after getting it running. I warmed it up in the shop,
re-started easily and did the same thing the following days. I went for a ride and after about 19
miles came to the main road, accelerated up to 70 briefly, backed off and the bike wouldn't run over 45
It sounded as though it was starving for fuel. Got to a stop sign, killed it on
take off, couldn't restart, had it towed home. Both plug porcelains were white. The electrodes still looked new.
Could not restart in my shop. Checked the mag with my see through spark tester, #1 shows hot, #2 can' see
the spring in the tester light up. Bench test at extreme low rpm shows spark on 1 & 2.
I know the jet block in the front carb drops out on its own, while the front one is push fit, and the carb
body must be heated with a blow dryer to coax it loose. Could the loose jet block be sucking air?
I recall weeks back starting the bike with the Lucas, it ran for 45 seconds and died, and it was on ultra
high idle when it died.
I put the old jets back in, still could not start.
I'll install the new needles and jets tomorrow, and want to wait until my B-TH is fixed or will buy a new
one. The mag is probably 100% good, as it has started and run the bike 15-20 times, but only in the shop.
My starting procedure(s) are still a work in progress as I'm trying to release the decomp at the bottom of
the stroke, but am late sometimes so not getting a full swing. Nevetheless, I can start the machine, and after
it's warm, it fired ever so easily. That's past tense unfortunately.
