No starting '99 F4
 

I will make this as short as possible. Yes, I did my winter maintenance (battery bought in novembe and put on trickle charge, plugs, fuel filter, air filter & oil change, stabilizer in fuel for storage). Rode some when it wasnt too cold and started it here and there to make sure everything was ok. Pulled it out for a short ride in the morning, no problem. Went on a ride with speeds exceeding 100+mph, still no problem. coming off the hiway, I start to lose power @ light. it goes dead. about 30 minutes later with the choke on and the throttle open, we got it to start and run again. So we continue riding, Fuel light comes on, so I go fill up. About 5-10 minutes into ride on the interstate, I throttle it and felt power loss, I immediately pulled over and it died right there. Will not start @ all. Please help.

check your valve adjustment, have you done that yet
i have a 2000 f4 with 35000 miles. my bike did the same thing
when i went to do my adj my #1 journal was scored bad i had
to replace the head running good now but the reason why it wasstalling
was because i had alum shaving in that jornal probably seizing so after
bike cooled down was able to start back up and ride some more
find out what it is before something serious. need more reply let me know
