Trouble Starting When Bike Is Hot (sometimes)
This has happened to me about 4 times now, and still haven't figured it out exactly. My best guess is vapor lock.
I have a 2012 XCT, everything is stock. Not long after purchase (<500 miles) I was in Denver, stop and go, and parked the bike. It was pretty warm, in the 90's, but not overly so. The bike sat about 10 minutes. When I went to start it, the motor wouldn't fire. I gave it a bit of throttle and finally got it to start though it sounded like crap at first until it smoothed out.
Last week I was in Chicago, it was a very hot/humid 100+ degrees. I stopped at a gas station to hydrate the wife and myself, but didn't fill up the bike. We each drank a gatorade (the humans, not the bike) and then got back on. Same thing as before, she (the bike) wouldn't fire. I hit the starter about 5 times before she fired and idled very rough, backfiring and running like crap until I got her revved up for a minute and it steadied.
A few days ago I was headed back to Colorado and was somewhere in Wisconsin. Again it was hot so I stopped to get a drink. Tried to start the bike and the same thing happened again. I popped the fuel lid right away to see if that helped and it didn't. I gave it a lot of throttle this time...enough to smell gas...and it finally started again rough idle until I got her revved up and then she ran smooth.
Any ideas? It sure acts like vapor lock, but I haven't seen any posts with a similar issue. I can stop in the exact same conditions with no issues.
