Question about 2007 Yamaha XT 660 X
Hi, Jay and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a "LOAD" test if necessary, your battery may show 12.5 volts but have little or zero amps and needs to be replaced.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, stator, magneto, points/condenser ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.
10. Accelerator pump damaged or not working.
11. Water or dirt in the fuel system, carburetor or filter.
12. Restricted, blocked or kinked fuel line.
13. Fuel tank empty.

i had a simuler problem with my honda cr 250 moto-x bike it would start fine and you could keep it ticking over with the throttle(i have deliberatly unscrewed the tickover in case i come off,it will cut out) when i got on it,it would go for about 400-500 metres then splutter and die and not start again for around 5 mins. i immediatly knew it was a fueling problem. so after stripping the carb and giving it a good clean out i was baffled when i got back on and it still done the same. i then dismantled the fuel tap cleaned it all out and put it back together and tested it,it was very very slow so i unsrewed my fuel cap a little and was greated with the familur gush it should deliver. problem solved! the vent in my fuel cap had crystalised up,so the fuel was coming out but the air was not getting in,causing a vacuum and slowing down the flow and basically emptying the carb quicker than it can fill back up!!! clean your carb,fuel tap and any vents in your cap or tank. if this does not work then your bike must be over fueling or low on compression.

i had same problem turned out to be electrical issue check all your wiring connections under the seat and under your fuel tank and if there all fine try checking that your fuel pump motor is running mine wasnt because of damp on my wiring connectors. when you turn on the ignition the bike should click a few times and your fuel pump should come on look under your tank looks like this with 2 tubes running from your fuel tank http://cgi.ebay.co.uk/yamaha-fzs-600-fazer-00-fuel-pump_W0QQitemZ250559832283QQcmdZViewItem?rvr_id=&rvr_id=&cguid=6d2769071260a0e2048322d3fffcee00
this needs to be running or you will be riding the bike on gravity fed fuel and as soon as you open the bike up you will not get enough to the engine and will cut out hope this helps
