Hi everyone. On Friday I did some maintenance on my bike before the season started including a new chain, changing spark plugs and oil change. I drove about 35 minutes on Saturday and everything was fine. This morning I was going to work when all of a sudden my bike bogged down a little and then lost power completely. After about a half an hour I got it started again and then made it about another minute before it died again.

I'm not positive if the oil pressure light came on because the bike had turned off, or if it turned on just before the bike actually died, but I wanted to add that just in case it triggers something with anyone. I'm also not sure if it's a spark plug issue because if it was, should it not have shown issues before about 45 minutes to an hour of riding? Anyone know what it might possibly be?

I would drain the carb float bowls first, to see if they have fuel in them, and drain them again after trying to start your bike again, to show that the fuel pump is working and there are no clogs in the fuel system. Did you put a fuel stabilizer in the fuel tank and run the engine enough to get it down to the carbs before long storage? Cycle World magazine had a good article about ethanol problems recently.

Next, remove the spark plugs and hold them against a ground with the wire attached (with a glove on) and turn the starter, to see if they have a good spark.

since you worked on the bike, ran it, parked it, then had issues, go back over everything.

make sure the gas lines under the tank arent kinked. if the bike was parked before did you change the fuel filter?

do you hear the pump when u turn the key?

i had an issue where i didnt tighten my plugs enough, different symptom but still. have to go back.

if you pull the fuel line from the carb side and turn the key the fuel pump will shoot gas 300 feet in any direction. not a good way to do it but a test nonetheless. get a bucket and safety glasses. haha...

disclaimer... I am not pro, I have probably done more damage than good. hope this helps.

Thanks for the response to both of you. I've been slightly busy with work the last few days, but I'll be getting to it either today or tomorrow and can update you on if I got it going or not.

So, I did all that. Carb float bowls all have pretty much the exact same fuel levels after I drained them and restarted. Plugs looked good too. It doesn't seem like I've forgotten to attach anything or anything was crimped... Not sure what to do next?

so what's the current symptom? it will ride for a short period and shut off? (bog down)?

does it start up immediately after? does it stay running idol?



how old is your battery?

So, when I first started it, it had started and ran perfectly fine. When I went to take it the next day it started completely fine, and then it just ended up dying. After about 15 minutes it started again, but only went another minute or two and died again. From there, I had to go to work and so came back a few hours later and when I tried starting it, it started fine but only went a minute maybe again and died. I left it where it was until the next day and when I came back the next day to see if I could get it home it started. It took a little bit but it did start, however, as soon as I gave it the slightest bit of throttle it died. So, I towed it home and now it won't start. When I try and start it, it will almost start but not quite. My battery was brand new last year, and considering it started just fine before, I don't think that's the issue?

I just realized I didn't actually check the fuel pump solution you suggested... So, when I drained the bowls they did have gas, however, when I took the line off from the carb and turned the key, nothing happened.... Perhaps my fuel pump has just enough power to put fuel into the float bowls, but not enough to actually start the bike?

Just checked the fuel relay; the 3rd and 4th lead says it should be 1 ~ 5 and mine read 9. Anyone know if this being high would be causing problems?

If it loads the bowls with fuel, its working well enough to start it. It's only when the bike is under load (half or more throttle for a consistent period) that a failing pump will start to be a problem.
