That's not quite the question but here's what happened. I filled up fully the day before yesterday, rode about 3 miles to home, then yesterday morning when I started the bike all was well, but it stalled after about 15 seconds while I was waiting for the bike to warm up, putting my helmet on etc. I started it again, started right up, then proceeded to stall again. Never happened in 41K miles so this was new. I surmised maybe a vacuum was happening in the tank so I opened up the gas cap, restarted and it never stalled again, and ran completely normally for a 40m ride. Is it possible it had to do w/ a vacuum, or what else might be the cause?
