Question about 2004 Honda Metropolitan Base

1 Answer

Honda metropolitan I'm having trouble getting the scooter to start. The engine will sometimes catch and go for a few seconds but then it usually dies. If I'm lucky enough to get it to stay going, I have to keep the throttle mid-range to keep it going. If I let the throttle close, it will die. If I open the throttle all the way up, it dies. While it's running, there is a small popping sound as it runs. The scooter has 20K miles on it.

Hi and welcome to FixYa,

Initially, a few possibilities you may want to check/explore:

  • stale gasoline;
  • clogged fuel filter (inside the tank above the fuel shutoff valve;
  • clogged, bocked, varnished, gummed carbs, jets, air pin holes;
  • stuffed air filter/box;
  • vacuum leak (rubber coupling, manifold side);
  • air leak (airbox base assembly seated/fitted on the carbs.
Basically, a general cleanup of the fuel lines, tank and the carbs. Sitting for some time tends to leave varnish like coating on most parts.

Good luck and Thank you for using FixYa. Happy Holidays.

Try balancing ans syncronising the carbs.
BALANCE THE CARBS
Turn the throttle screw on the LEFT carb one half turn inward. Now start the engine and get it warmed up. With the engine running, remove the RIGHT spark plug wire. Adjust the idle speed on the left carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.

Now turn the throttle screw on the RIGHT carb one half turn inward. Restart and rev the engine. Next, remove the LEFT spark plug wire. Adjust the idle speed on the right carb to the point where the engine just can't quite stay running and dies. Now put the loose spark plug wire back into place.

Turn the idle screw on each carb EXACTLY ONE QUARTER turn outward and restart the engine. The engine will be probably be idling very fast. Adjust both the idle screws equally from this point to get to the desired idle speed.

SYNCHRONIZE THE CARBS
Remove the air filter and rubber fittings to allow you to see into the throat of both carbs. You may need a mirror to see inside. You need to be able to see the slides go up and down when you twist the throttle. Now turn the fitting where the cable goes into each carb such that there is just a bit of slack in the cable, 1/16" is plenty. Lock ONE of the cable adjusters down tight. All further adjustments will be made on the other carb.

With the motor turned off twist the throttle very slowly while looking at the slides. Both slides need to begin lifting at the exact same moment. If the slides don't raise at the exact same time then slowly twist the throttle until the locked adjuster slide just barely starts to move. Hold the throttle still and turn the adjuster on the other carb so that the slide on that carb just barely starts to move also. Now recheck the slide movement timing. Do this process until the slides on both carbs begin to raise at the EXACT same moment. Lock down the loose adjuster and re-check the slides.

Please rate this solution. Thanks!

If you have used Dyno jet kit I have had a kit come through with smaller main jets than the stock ones causing it to run way to lean.

SOURCE: My bike starts but dies right away what's wrong

Sounds as if you don't have any gas to give it! Turn off the tank fuel tap, remove the carburetor fuel hose, and place the end in a clean can or jar. Turn on the tap again--you should get a small stream of fuel running from the hose. If it just drips, turn off the tap again, unscrew the small bowl under the tap and remove the brass filter screen just above the bowl. Soak it for a while in carburetor cleaner, rinse in fresh cleaner, then put it all back together. Turn on tap again and check for fuel flow. If still weak, turn the tap to 'reserve' position--is the flow still weak? If so, remove the fuel tap bowl and place the can/jar underneath and turn the tap on again. If still slow, open the fuel cap up on top to make sure that tank vacuum is not stopping flow. If nothing helps, you will need to remove the tank, drain the fuel out and remove the fuel tap to clean the two tubes that are sticking out of the top. You may need compressed air to get this accomplished. Good luck!

SOURCE: bike starts and runs fine with full choke, once

Same problem, runs fine with choke on, but when i touch the throttle it bogs out, sounds like its not getting any fuel. I cleaned out the carb and used fresh gas, but the problem persists. I'm going to try cleaning the air filter and getting a new plug. If thats not it it could be eletrical.

Starts and runs but will only go 25 top end and 10 going up a hill. I cleaned carb, and changed plug. Filter good. Any help about how what to try next?


Dennis, Write up found in scooter guide.net link below.This scooter was restricted to 25mph via a series of restrictions to the variator, ECU, intake and camshaft. 2009 was the last model year for this CHF50 in Canada and the USA, although this scooter was available for a few years after this due to excess inventory from the 2009 crash of the scooter market.
You can have it modified at a shop probably $$.
Check the attached links,instruction and guides, Good luck

I have a 2011 Vespa LX150 that has trouble starting every time. Most of the time, it continues to turn over but won't catch; sometimes it just makes a winding noise (like a wind up toy). I can usually get...


probably the starter relay has a malfunction.
- Or the gears on the starter were once damaged when you pushed the starter button by mistake while the engine was already running?
Usually the engine starts on the second try - if the battery is really good then you better try to live with that.
Buy a Voltmeter to check the battery charge.
