So I have this little honda spada that I have effectionately named Renata....maybe thats the problem...anyway - I take off, she rides beautifully - as long as she is properly warmed up. Purrs and plays nice. can ride for as long as I want at this stage. The problems start after I stop for a while. This can be for any period of time. After I start her up again, she might go for a km at the most before she starts chugging like she has dropped a cylinder or run out of fuel etc...not really sure...not the most technical person really. Once she stalls (which will happen very quickly if I drop the revs - I tend to just floor it until I can get to a side street or a shoulder somewhere safe) the only way to start her up it to open the fuel tank - maybe an airlock there - again not sure - then give her full choke to start and back it off again....once this has happened this process will happen the whole way home....its just a matter of picking the safest route and hopping home. Can anyone suggest what could be the problem?
