Well shazaam, happened again. On the return leg of a 100 mile ride today I started sputtering and just conked out. Pulled off the gas cap to release the vacuum and all was good. For about 2 miles. Repeated as necessary about six times. When we got to my bud's house pulled the vent valve do-dad from the line. No rattling going on. Blew a bit of compressed air through the nipple and must have broken the ball loose. Was rattling freely. Made it home about 15 miles at 75 mph without another stall. Hope that does it for awhile. I'll try to find some dry graphite as suggested by singring.
Just curious...can you run safely without the vent valve?
