Question about 2009 Keeway Matrix 50

2009 Keeway Matrix 50 hard to start

I own a 2009 matrix 50 I have to goose the throttle to get it going once I travel 100 yards or so it seems to run fine. I have changed the spark plug with an NGK BPR7HS and it ran a little better for a few miles. It only has 2200 miles on it. It also has a hard time starting at times. Can you help me, please? @

Hi, Fmapalategui and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.
10. Choke valve inoperative.
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.

SOURCE: wont accelarate

you didnt say if the bike sat up for a while, if it has you have stopped up carbs the bike will run with the choke on but shut off when the choke is off says no fuel going thru the low speed jets clean them by taking the float bowls off and blowing them out with high pressure air

SOURCE: Engine skips, won't go over 55 mph. Works fine below that.

Hi ..... Go through the above list, pay particular attention to fuel delivery ie blocked breather in tank, any filter fitted to tap or change in line filter if fitted. Easy to check, take off fuel delivery to carb (place container to catch fuel), start bike and fuel should come out a strong contant flow.
Let us know how you get on.

Hi
I would suggest that you have the valve clearances checked.

Also, check that the carb is clean. Pay particular attention to the PILOT JET as this opperates the idle circuit.

SOURCE: Hello I have a 1996 Suzuki DR-200 and recently put

G'day mate the 1st thing i would go for is float level then compresion if it does have the **** it wont take the fuel in , rules are if it has **** ( induction ) Squeeze (compression) Bang ( spark) and Blow (free exhaust) then it should go, if it was running to lean there is good chance it has a burnt exhaust valve which will greatly drop the compression/induction, also check the valve clearence. hope this helps

Hi i have keeway matrix 50 motorcycle 2008. I want ask you where is are speed blocker


Usually a restrictor plate in the mouth of the carburettor. Restricts the amount to air and therefore the fuel intake as well.

If it is fuel injected, it is done electronically.

The carburetor needs to be removed and cleaned, water must be in it or some rust from the old can must have got into some of the injectors.

My tail light works fine but when i hit the breaks it doesn't brighten up everything is connected and i'm stumped.


Check the light bulb. Chances are that the brake light filament is burned out but the running light filament is still good. If the bulb checks out okay with a multimeter, check the brake light switch and the wire connectors..
