I thought I would just share my latest little adventure with my f2. Hopefully it can save the time for someone else.
The other day, I was heading to the gas station before heading downtown. I knew I was low on gas, yet hadn't switch to reserve yet. A km or two away from home, my bike starts farting and sputtering and dies when I come to a stop at a light. I pull over and try to switch to reserve, no luck. I got some gas from the station and made my way back to my bike, still no luck. at this point i thought i flooded it. I left it there and took the bus to my date
That night, I went back and after a couple tries, it fired up and I rode home fine. I thought everything was back to normal.
The following day. I took it out for the day. riding probably at least 30k throughout. No problems
next day, wanting to let my dad try it out, I start it, idles fine, rpms start dropping, try to keep them up with throttle a bit and then stupid me, try to ride it out. it dies the same way as the previous day and i walked it home.
So I thought that i might have gotten crap out of the bottom of the tank when it was nearly empty.(its pretty rusty.) My guess was that it was a gas issue since i was noticing some farting/loss of rpm before it actually died. A mechanic told me an electrical issue would be a sudden death kind of thing, but i guess in my case, i had an intermitten connection.
I took the petcock/filter out, just to see that the filter was in rough shape and i had to dispose of it. Got a new one. cleaned petcock diaphragm, took carbs out, since i knew gas was making it there. Openned them up and they were still clean from when i got the shop to clean them. filled up again, still no luck. I then notice that this last time, i forgot to flip the kill switch to on.. and it was acting the same way. starter goes, no combustions signs. Also, another thing i noticed was that the bike would lurch forward abit unless i had the brake down. Anyways. then i flip the switch on, same reaction.
I open the housing only to find a kill switch connection holding on by a thread. I re-soldered it and now it starts again. and I rode to work..
So.. at least now i know my bike a lot better than before, but that 15min check and 15min repair felt too easy after the hours i spent taking the carbs apart.
live and learn. If this saves someone the same trouble i will be happy. If anyone has troubleshooting tips that might have helped me in my conclusions, I'd be grateful for them.
