Question about CCM RC 30 Motorcycles

1 Answer

I've recently had a problem with getting my bike started, i have managed to get it to start now, but it can only be started with the choke fully open and if i try to close the choke it cuts out. (Even when the bike is warm.) Also if i try to aply the throttle a little it sounds as if it is flooding the bike and then it cuts out. Any help would be much appreciated? The bike is a ccm 644 r30 on an 04.

It is most likely fouled spark plugs. You can take them out and sand blast them, or buy new ones.
I had a CBR 954, and noticed that the spark plugs fouled out pretty easily because it runs so rich at startup (and I would shut it down during the 'warm up' phase).
Here is some more information for you:
From http://answers.yahoo.com/question/index?qid=20080806081249AALKibM
What are signs or symptoms that spark plugs in a motorcycle need to be changed?
There are several things that could hint at bad plugs.

- Hard starting.
- Slight to severe hesitation when you give the bike some throttle.
- Stalling, especially when you give the throttle a good twist
- uneven idling (tends to zoom up, or down, or sputters)
- After running the bike for a little bit, take out one of the plugs. If the end of the plug is wet, its not firing, and it could be oil fouling the plug
- take a look at the color of the end of the plug -- if it is white, its running too hot, and it can cause misfires
- look at the same area, and if it is covered in black soot, it can be poor gas mixture and dirt in your tank causing it to foul
Hope this helps.

Turns over but dose not start, spark plug sparking ok


Check you have petrol if the bike has not been run for sometime replace the fuel. Petrol ages and causes all manner of problems.
Are you trying to start the bike but it has gone onto reserve, move the fuel tap to the reserve position then try to start it. If the above fails, then try these:-
Is the spark plug wet when removed. If dry it sounds like the petrol is not getting through. Try opening the filler cap and leave it open, make sure the kill switch is in the run position. Try starting with the throttle full open. Does the bike have a manual choke try to start with the throttle shut, choke off, then full on, then while continuing to turn over move the choke lever in stages from fully on to fully off. I find on my Yam TW125 (winter and bad weather hack) that if I have not used it for a while sharp twist the throttle a couple of times no more than a third of a turn. Hope this helps.

Bought my stunner recently,3 days back.Today when i was trying to start it by self start,it was not turning on but made choking sound..All other stuffs are working good...Since there is no kick start...


the only way i know of starting the bike by pushing it is to get up to 40mph

but before that is the battery fully charged? also i would drain the fuel tank and put in new fuel then check the spark plug is working by removing it from the engine and laying it on some metal and seeing if it sparks
if it still dosnt start then the carb needs a clean

hope this helps

I ran my newly purchased 2004 FatBoy last Saturday, and it was wonderful.....tuned so sweetly. But now, today, the second time I've had it out, it was running very rich, to the point it was difficult...


Your bike is not equipped with a "choke" per se. It is equipped with an "enricher" circuit. Although both systems are meant to provide a rich mixture with which to start a cold engine, they do this it completely different fashions. If you were to ride the bike with a "choke" partially on, it would run very rich. But, once you crack the throttle plate open on an "enricher" equipped carburetor, the enricher is rendered inoperative. An enricher only works when the throttle is fully closed.

If you're running rich and fuel is splattering down the right side of the bike, you've got other problems in the carb. I would suspect that your needle and seat is not sealing like it should for one reason or the other. If the bike sat up for a while, it could have some residue on the needle and seat left from the gasoline evaporating or something. I'd go purchase a can of carb and injector cleaner and pour some in the fuel tank. Do not allow any of this to get on your paint. Try that for a tank full if you can. If that doesn't work, the carb needs to be taken off, stripped down, and thoroughly cleaned inside. Maybe install a new needle valve. The seat is not replaceable in the original carburetor.

Good Luck

My 2003 suzuki gsxr won't star has been sitting in the garage for three months without starting it cranks over pretty good, did I choke the engine with too much gas trying to start it?


Hi from Spain,

no way to choke this fuel injected bike in theory....but by my experience try to start the bike with fully open throttle several times, take care do not flat the battery, if the bike has not much fuel do not try with the bike on the side stand so the fuel cannot reach the fuel pump inlet.

BR,

Emilio.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

sound like the carbs need to be synced if throttle plates are fully closed at start it would cause a rich condition and no need for a choke becase there is very little air passing through mostly fuel if they are not eqaul there would be hesitation when opening throttles til about 1/4 throttle

your BMW75 has a cold start sensor fitted to its fule system the choke leaver dose nothing but raze the reves a little its not a choke,,,thats withing the fule system if the sensor is not working right it wont tell the fule pump to enrich the fule mix and it will be hard to start from cold,,also if you start the bike up you must run it till its hot or the choke will stay on and flood up the engine the next time you try to start up
the choke sensor is in the water jaket, try changing this part first

Poor starting from cold


If the bike has been sitting for a long time (a year or more) you could have plugged up carburetors. Also, make sure the choke cable is adjusted so that it moves the choke fully when the handlebar mounted choke lever is operated. You may not be getting a full-rich condition when cold starting. Make sure the clamps that hold the carburetors to the intake boots are tight. Air leaks will cause both poor starting and poor performance (and possible engine dameage). Also, don't open the throttle excessively when cold starting.
Aside from all that, make sure all of the normal tune up items have been done recently (valve adjustment, new spark plugs, air filter, etc.).

Choke won't open or close


I think your bike has a CV carb which doesn't have a choke.It's called an enrichener. Pulling out the "choke" knob merely dumps more gas into the carb. If the bike starts normally with the knob pulled out, you do not have a problem. On a cold/cool day, pull the knob out and start the bike. If it idles faster than normal the system is working. Pushing the knob in should drop the idle speed, maybe stalling the bike if it is not fully warmend up.

Wont run /idle


i'd start with removing the carbs and giving them a thorough cleaning as when bikes sit for so long, the carbs begin to get gummy/varnished from the old gas.

check for blocked holes in the pilot jet & main jet and look for "hard & dried up" gas in passages. be careful of the float bowl gasket as to not tear it or you will need a replacement.
