SOURCE: Engine revs when turning right.

being an older bike, maybe a wire from the hand controls is shorting out, even in side the handle grip switches, or going down the neck under the tank. normaly a throttle cable problem would cause the rpms to go up when turning the handle bar, thats why im suspecting a short

SOURCE: suzuki bandit 1200 W reg missing under load,

Sounds like a mix issue and things are working and adjusted going into the cylinder.

Is your exhaust clogged? Is the condensation water draining correctly (your tail pipes are high so water collecting in the exhaust on cold engines will stay in the bottom. It could even build up if you only take short trips and your small drain holes are clogged. I've also heard of a kids sticking things into exhaust pipes before!

Finally, sometimes rust or other causes clogging. Unfortunately, I don't have an easy way for you to check it.

I have a ccm 644 that won't start bought new battery and checked the air filter which had oil in the bottom of the filter box. Turns over no problem but no start any ideas.


Hi, Philipirk and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, 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.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

I have a ccm r30 644 2004. The bike will not start i am getting fuel to the carbs but i presume its not going through to the head. I have taken spark plugs out and checked them i have also added a little...


dump the float bowels and inspect/ clean as necessary. consider buying an acid bath solution sold at your local parts store just for this sort of thing or carb cleaner and a toothbrush. you may need to clean your current/ buy new jets for your carbs. just try spraying starting fluid into the carbs while starting the bike by removing the air filter first and try to keep it going as long as possible this may get the juices flowing on its own. goodluck

Bike won't stay running


Drain the carburetors. There should be a screw on the lower side of each CARB float bowl. Remove the screw then replace it after the fuel drains. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Install new stock NGK spark plugs.

Remove the CARBS from the bike.
FOR EACH CARB > 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 idle screw and the air screw 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. Install an in-line fuel filter. Let the float bowl fill then start the engine.

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.

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.

Turn the idle screw on each CARB EXACTLY ONE HALF 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. Congratulations, you have just balanced and synchronized your CARBS This should fix the problem. One last and VERY IMPORTANT thing, Have a fire extinguisher handy and ready for use any time you work on or with he CARBS.

Please rate this solution. Thanks throttlejock!
