Just an update on the "leaving the petcock filter out to get better fuel flow" sitcheeashun.
Last night I thought of a little filter that I picked up somewhere back in the Dark Ages so I went down & found it in the spider webs this morning. The In & Out were a perfect, very tight fit for the fuel hose size I'm using. No clamps needed. The In & Out are adjustable a full 360 degrees. The filter mesh seems to be brass or bronze.
So I hooked it all up & the hose immediately glug-glugged itself full. Let it sit a while; no leaks.
Got dressed & went for a ride. No sign of fuel starvation. Perfect.
Got home, shut her down & the hose shows full of fuel unlike before when it always showed a big bubble.
PS: The engine is marvelous, Ace. Revs so easily now. Coming off my exit (90 degree easy curve) in 3rd at 30 onto a straightaway, 45 is so easy & quick in 3rd that I think I might see what 50 feels like (wish I had a tach) next time. 55 & 60 now are so smooth & easy. I put the long UCE kicker back on; the 9.8:1 is a killer for an old cripple who won't give up, but I'm getting very close to not needing that 2nd & sometimes 3rd kick any more at all. It's mostly 1 or 2 kicks now. ES is instant. I just whisper the word "starter" near the bike & it's running.
