SOURCE: engine clutch mess

Check your kick stand sensor if it's unplugged then there is your problem. If it's still plugged in then the sensor might be gone. The sensor shuts the bike down if you try to take off when the kick stand is down. you can bypass the sensor by jumping the two wires before the sensor with a piece of wire connecting the two leads together. doing so will allow the bike to be put into gear with the kick stand down so always check it so you won't have an accident. good luck and get out ridding!

Anna14 is right with the air leak,this can also be a misadjusted or faulty throttle position sensor or defective CDI Unit or a lean feul mixture.

SOURCE: Battery will not keep a charge.

Get a 2 amp charger and charge the battery fo 3 hours or so. While the battery is charging,check the fuses and check the wiring harness connections between the flywheel and the battery.

Start the bike and rev it up. Use a DC voltmeter to check the battery voltage while running. The voltmeter should read 14+ volts. If not then there may be a problem with the stator.

Pleas rate this solution. Thanks!

SOURCE: I HAVE AN OLD YAMAHA SR 125 ITS REVS GO UP AND

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw. This process should get you back on the road.


Since you mentioned uneven idle revs, be sure the carb and manifold are on tight and also tighten the cylinder and head. Air leaks can screw up the idle.

Please rate this solution. Thanks speedfreak41

I have a 2008 hyosung gt250r. All of a sudden it has started this issue. Where i start the bike in neutral then go to get first gear and the bike just cuts out each time..so ive had to start off in second...


The problem is the side stand cut out switch - it allows you to start the bike to warm it up on the side stand but if you true to ride off with the side stand down the bike will cut out reminding you the stand is down.
If you bike is cutting out when putting it into gear after starting it is definitely the cut out switch - check the side stand there will be a switch around it some where close to were it bolts onto the frame.

Bike will not move under its own power


Sounds like your clutch is getting stuck in the disengagement. Follow the clutch cable down and check to see if its moving or stuck.

Sometimes will not downshift into any gear.


Hi, When you shift do you have high RPMs. Try lowering RPMs when you shift.
Also you said it gets warm. Try using a different oil (heavier oil). Hope that helps.

Runs bad under 3000 when riding like in the wrong gear


Hi, Tim and the usual suspects are:
1. Spark plugs in bad condition or partially fouled.
2. Spark plug cables in bad condition or leaking.
3. Spark plug gap too close or too wide.
4. Faulty ignition coil, module and or sensor.
5. Battery nearly discharged.
6. 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.
7. Intermittent short circuit due to damaged wire insulation.
8. Water or dirt in the fuel system, carburetor or filter.
9. Fuel tank vent system plugged or carburetor vent line closed off.
10. Carburetor controls misadjusted.
11. Damaged carburetor or intake seals.
12. Loose or dirty ignition module connector at crankcase.
13. Faulty MAP, CKP, O2, and or CMP sensors.
14. Incorrect valve timing.
15. Weak or broken valve springs.
16. Damage intake or exhaust valve.

Engine cuts out when approaching a roundabout or junction, when slowing and clutch is down. Changed the speed sensor a few months ago which we thought had worked, problem came back yesturday


hi...
this is may be due to the idealing problem.set the idealing in correct amount so that it doesnt stops.

considering the speed sensors check any signal comin to the sensing unit is getting intruppted.

i think only these are the problem wihch may be the reason

Clutch dont work


This is a easy fix. All you have to do is let the bike warm up a few minutes before you take off. I would like you to try it your way first. Then let it warm up for 5 mins then see what happens, you can warm it up faster by reving the engine but let it run for 1 min before you rev it up. Enjoy your riding.

Cut out


did everything as usual letting the bike idle for 5 minutes while I got my gear on. Got to the end of the road stoped then as I opened the throtle to pull away it cuts out. Restart then as I get to the next junction does it again. Pull over a bit to give it some revs, all seems fine, nice idle etc, then does it again at the next junction as I try to pull away. After that no problems at all, went out for an hour or so didn't miss a beat, was out on it the day before to with no problems. Anyone else had any of this sort of weirdness on their 690?,check out the fluid in the clutch reservoir. I was loosing some oil from the slave cyl. and when there was a lack of oil exactly same thing was happening to me.,,,
