QuestionLast week I rode my bike home in good weather put it out back and went went away for the long weekend leaving it uncovered and with fuel still turned on (forgot to turn off) while i was away in rained non stop for 3 days.
When i came back the bike wouldnt start. it ticks over a couple of times then dies. iv had it on idle for 20 sec at the most before it cuts out. any attempt to add some revs and it cuts out immediately
So far iv:
1: changed fuel
2: changed battery
3: changed spark plug
4: changed oil
5: adjusted f/a ratio screw
and still i have the same problem... i would drain carb but i cant find the screw to do so.
What do you think they problem may be?
Thanks
Sean
AnswerBefore your question I had never heard of Shineray motorcycles so I looked it up on Google.
I don't like to be the one to tell you this but, from what I've been able to find out, I'm afraid that the problem might be simply that you have a Shineray XY200GYE.
I haven't been able to find any useful information on keeping them running, but I did find a number of comments on how poorly made they are and how soon they fall apart. Based on their opinions it's amazing that your 3 year old machine has not disassembled itself.
I did find a forum for Shineray owners. Maybe someone there can tell you how to drain the carb. http://shinerayforum.com/
Your problem does sound like there could be water in the float bowl and draining it would be one of the first things I would try (along with the rest of what you have tried), but a number of other things could also cause similar symptoms.
- If the insulation on your spark plug wire has deteriorated it could be "leaking". That is, the high voltage pulses that are supposed to produce the spark could be shorted to ground by moisture in the insulation. You could try drying the lug wire with a hair dryer and see if that helps.
The same goes for the ignition coil.
Normally, the insulation on motorcycle spark plug wires will last at least 10 years and the insulation on coils for 20 or more, but with Chinese export goods you can't expect the same quality of materials.
If drying the wire and/or coil out solves your problem, you should replace them so that you don't end up stranded in the rain. I would recommend a higher quality aftermarket part if possible.
Make sure you have good quality copper core spark plug wire. Do not use automotive resistor type plug wire - the resistive material they use instead of copper will only last a couple of years if you are lucky.
- Have a look at the air filter. I have no idea what yours is supposed to look like, but I saw a picture recently of a Honda Shadow air filter that had been stuffed with acorns by a chipmunk when the bike sat for a few days. Mouse nests in motorcycle air filters are pretty common too.
For that matter, when did you last replace the filter? If it is getting near the end of it's useful life (read: nearly clogged) and has become saturated with moisture from the rain it could be the all or part of the problem.
- While you have the filter out to examine it, check inside the airbox to see if it is wet with fuel. It is possible that you have a leaky float valve in the carb and that the fuel that got past it has flooded not only the cylinder, but the air box as well. I am not familiar with your machine so this may or may not be possible (it depends on the relationship between the locations of the carb and the airbox).
