Question about 2000 Harley Davidson XL 1200 C Sportster Custom

1 Answer

I have an 01 1200 XLH. Road hard and "put away wet last fall", no winterization. As penance I have removed and cleaned tank, carb, etc. I appera to be geting gas and the bike fires fine but won't hold an idle. Whether "entiched" or revved, she'll run for about thirty seconds and dies. You have to turn off and then back on for it to fire again. She fires, and then the same routine all over again. A buddy suggest switching out the primary circuit breaker. I'm wondering if that isn't just a symptom rather than the cause. Like I said, you have to turn it off, wait just long enough for it to recycle when you turn it on and she fires, then dies!?! Any thoughts would be helpful. Thanks! Bill

You don't mention any other symptoms so I will assume the electronics, ie speedometer, tach, and such, did't start acting weird? If that is the case check your grounds these old rigid mount sportsters are known for vibrating the grounds loose.

SOURCE: High Idle On Start-up.

Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.

SOURCE: Bike won't start

It sounds like an ignition timing issue, you need to reset the timing follow the repair manual's procedure, there is usually a mark on the backing plate of the stator that line s up with a notch on the case. Depending upon the direction of the fly wheel rotation the stator's back plate notch must be about 1/8" advanced in the opposite direction of the flywheel rotation, in other words in order to get the timing set from zero (which is when both the notch and the other corresponding notch or scribed line are lined up to one another perfectly) you must slightly move the stator plate toward the direction of rotation then lock down the stator plate hold down bolts. Be aware this is a generic description of the procedure. My observation in the past dealing with rebuilds is that the timing must be set to a static timing setting (which I just described) to get the bike to start initialy then fine tune the timing with a timing light, this is a procedure that should probably be done by a bike shop but you can do it yourself with the appropriate specs, tools, and maybe a repair manual and a little overall knowledge which it sounds like you possess.

I bought my son a craftsman snowblower last winter we can’t get it to start.It tuns over and over.Help needed.

If last year, you didn't drain the gas from the tank and carb or put fuel stabilizer in the gas, the old gas has gunked up the carb.
Remove the air filter and squirt starter fluid into the carb and see if it will crank. If it runs even a little bit, your carb needs cleaning.

Husqvarna lawnmower will not start after sittling idle for winter. Bought new last fall.

I fear this is stale fuel in both carb and tank, drain the tank, if the carb has a float bowl remove it and empty the contents, refill with fresh fuel and pull until it fires up.

Can"t get my 110 panther started since i set it up for the winter

Hi there, I am assuming, because you didn't really clarify much, that you did not properly winterize the bike, and there are a few issues you could have. First, if you did not drain the fuel out and did not put stabil or a similar gas additive into the tank, the fuel is probably bad, and I would drain the old gas out and place new in. If you did, do that, then I would move onto the carb, as I have the panther 100 dirt bike and their carbs are not the best to say the least, and could use a good cleaning every now and then, especially if before you put the bike up for the winter, you did not start it and shut the fuel off, letting it run till it stalled out (which clears out all the fuel in the lines and bowl of the carb. It is relatively easy to clean a carb by loosening the clamp on the intake hose, unthreading the the throttle cable assembly off the top, and loosening the other clamp on the opposite side; and removing the carb from the bike. Next, remove the bowl of the carb off the bottom by removing the center bolt on the bottom. More than likely, once the bowl is off you will see deposit build up in the bowl and the jets, and using a carb cleaner and rag to clean out the bowl, and using a screw driver to remove the pilot jet, a correct size socket to remove the main jet, spray each and every passage with carb cleaner and use an air hose to spray out any debris will usually suffice. Warning, do not use any type of metal object to try and scrape out jets, as doing so can cause damage to the jets.

If that doesn't fix the issue, than remove plug and check for spark by placing it on the head and kicking it over. If you have a good spark and the carbs are clean, and it ran fine before the winter, I would move on to checking the air filter for debris, and replacing if necessary, and lastly if all of that did not fix the problem and you have fuel getting into the engine indicated by wet spark plugs, than I would consider a faulty CDI box, which on the panther is a little black box under the seat attached to the frame by a piece of rubber, and regulates the spark. Hope this helps and good luck.

I have a 2000 Yamaha 650 Vstar with 3300 miles on it, we put new Vance&Hine pipes on it an had it rejetted, last year we didnt ride it very much, mostly sat in the garage, wnet to put it away an it...

This is a very common problem fpr bike that sit over then winter and/or rainy seasons. From sitting too long, the old fuel in your carb bowls have plugged up (varnished) your pilot jets and probably you idle fuel mixture screws too. Luckily your carb bowls and jets can be access without having to remove the carbs. For about $4 each, sometimes it's easier to just replace the pilot jets. If any of this is foreign to you, have a shop do it. And don't let them get away with quoting your the same charge to do the work as a V-Star 1100. The procedures are completely defferent and alot more extensive on the 1100.

I was using my "55"

First of all make sure the air filter is clean. Next I would dunp the gas out of the saw and put fresh gasoline oil mixture back in the fuel tank. Maybe a little condensation water got in the fuel you had in the tank.

Help with getting Yamaha 1981 Special running after winter.

Drain the old gas out of the tank to start with. Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? 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.
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. Be sure the bolts are tight. INSTALL AN IN-LINE FUEL FILTER. 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.

Please rate this solution. Thanks!
