I need air/fuel adjustments(# of turns in/out)for '02 CR125R
When I try to take off in 1st gear it acts like its flooding the carb, and tries to die unless I pull clutch in and rap the **** out of it. It only seems to do this after I've been riding for 10 or 15 minutes, not on initial start and run.

the cvh has a weber carb. these usually need a service every now and then. the smoke suggests there is a over fuelling problem and the dying of the motor sue to some flooding, i fixed a cvh this past weekend with the same problems. make sure that all the air hoses are also connected to the various ports
Are you running a carb? If so then check to make sure the choke is fully off, also check to make sure that the vent hose from the carb isn't blocked, and also check your gas tank cap. The easy way to do this is to crack it open like you are going to take it off but just enough so that there is no restriction of air into the gas tank. Leave the cap on the tank. Start it and see what she does. Sometimes what acts like flooding out is actually fuel starvation
Also, how old is the gasoline that you are using? If it's over a month old drain it and put in fresh.
Has your bike sat without running for some time? If yes then the carb could be junky and need cleaning.
Have you put any aftermarket parts on it? If you have changed the exhaust pipes, the carb needs to be tuned to the new pipes and if you went to a K & N style airfilter that is going to mean carb tuning as well.
Another thing is to check for vacuum leaks on the back side of the carb to intake manifold, and intake manifold to the heads. Spray bottle with water will cause the engine to react with either a increase in RPM or a decrease in RPM at idle
If anybody has been into the carb then you may have an internal vacuum leak in the carb itself.
Check all the simple stuff first and go from there.
It seems the carb/s flooding with fuel and thus it dies, try to reset the float pin and get the correct level of the fuel in the float chamber.
Standard procedure for air-mixture screw setting is u take the screw right in slowly taking care not to over tighten it as it may damage the tip of the screw.
Warm up your bike's engine and thn slowly turn anti clockwise the air-mixture screw to about 2 & a half turns and observe the engine's idling.
Before you attempt this setting(air-mixture) its better too, to replace the spark plug and set the gap to the specs of your bike's engine and check and adjust accordingly the valve clearance.
Hope this helps!
Remove the throttle stop adjuster and the air screw adjuster and spray carb cleaner in the holes. Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Turn the pilot screw 1/4 turn counter clockwise. Check the float level. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower.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. Adjust the idle speed with the Throttle stop screw. This process should get you back on the road. A “very helpful” rating for this answer?Thanks!
To begin with, do not try to start the engine with the transmission in gear. Shift the transmission to neutral. If the bike tries to move forward when you try to start the bike with the transmission in gear and the clutch lever pulled in, the clutch cable needs adjusting as the clutch is dragging and not completely disengaging.
If the engine is flooding, it sounds like you have trash in the carburator. Take your air filter off and try to start the engine. From a distance, look into the carburator and see how much fuel is going into the carburator. There should be a small spray of fuel if you turn the throttle grip. Otherwise there should be very little fuel going into the carb. If you see fuel pouring into the carb, you've got trash in your carburator. Unless you are very familiar with carburators, this is a job best left to a certified mechanic. You may have fouled your spark plugs as well. Either clean your plugs or buy a new set and install them. Sportsters are tough on spark plugs. Once they get fouled, they simply will not clear up on their own.
More than likely your clutch is fine, not burnt out. It simply needs to be adjusted, thats all.
The leak could be coming from most anywhere. Clean the bottom of the engine, take a short ride and then have a look. If you can't figure it out that way, put something under the kick stand to stand the bike as near to straight up as you can without danger of it falling over. Put a clean piece of newspaper under the bike and let it sit overnight. Look for the oil drip on the paper and then look straight up.
Yes, Your carburetor sounds like it needs cleaned. Or you may possibly need to purchase a carb. kit for your trimmer if the cleaning doesn't do any good. When cleaning the carb. use a Den Tek Brush, (teeth cleaning brush), to clean the small ports. Also, check the small screen in carb. Can get clogged easily.
Sounds like carb idle air or fuel jets are clogged.. Test pressure with a gauge to be sure. Float level and drop needs to be exact.. Operation of the whole carb relies on this. Probably why you are not getting any change in your air/fuel adjustments.
