Top 20 2003 Kymco Venox 250 Questions & Answers

If it idles and revs fine, then make sure there is no binding in the throttle cables. Turn your handlebars, right lock to left lock while twisting the throttle open to closed. Everything should operate smoothly.

Possible failure of the ignition unit. you need to trace the voltage to the coil, the trigger voltage if absent then the ignition system is defective. Check the input and also the 12 volt to the coil , if coil is heating it can be faulty.

I have the exact same issue. Did you solve problem?

Does it run with choke on? if so pilot or slow jet is clogged.or check the idle setting.

There are three screws holding the seat down. One at the back which is easy to see the other two you need to remove each top side cover (left & right) to access the other two. More info here

Leaving the gas in for 2 months won't hurt anything, my bike has been sitting all winter and is ready to go, except for a dead battery. Are you storing it somewhere that requires this? Just drop the fuel line and let it run into a container. You will always have fumes, and the carbs, if it has them, will still be holding gas.

Hi dewinnaarn
You can download a User Manual for your motorcycle from here This bike most probably has a vacuum operated fuel petcock that turns off the fuel automatically when the engine is not running. On page 40 of the manual I spotted a "fuel hose connector" that looks suspiciously like a petcock. Worth checking out. Cheers

You need a quality manual. Google it and search, you should find one some where on the web.
Now I will run you through the basics. Firstly check you battery terminals to make sure they are clean and connecting. Next, check that your battery is OK, easy if you have a multi-meter, but if you havent then just put it on the charger for at least 6 hours and see if it improves things. Now if you are still in doggie doo doo then it is time to get it to an Auto-electrician and get them to give it a test, generally done as a freebie. If they tell you that you electrics are all hunky dorry then it needs a tune up. I am not sure what your bike requires in that area but your manual should tell you. If you are not confident to do it, then take it to a qualified bike mechanic, or even to a Kymco Dealer

Hi Small vacuum tube goes to the inlet manifold, safety device to prevent fuel flow when not in use.

If you literally **** on it it will start and run!!

Loose the gas additive. Clean the air filter and then install new spark plugs. If the bike has carbs, drain the carbs. .... All fixed!

Could you take a moment and rate my answer? Thanks!
