My bike had the same problem... It was the battery. I have a new battery now and it works perfectly.

Hi It could be voltage drop and than the voltage drop protection circuit in the controller cut the power off. Your battery could be faulty. It could be just one cell faulty and it will affect all battery in some cases it is possible to replace faulty cell... if the battery lost its capacity because is old you need to replace it.

Loosing power


Instructions
  1. Power Wheelies
    • 1 Stand above the motorcycle with it running in neutral at the starting line of the track or one end of a long practice area. Pull in the clutch and shift the motorcycle into first gear.
    • 2 Begin rolling forward by rolling on the throttle smoothly and slowly letting out the clutch. When you are at a speed that is comfortable enough to put both feet on the pegs, lean forward on the bike and roll the throttle back quickly. Make this motion as fluid as possible so as not to overdo the wheelie. The front of the motorcycle will rise off the ground.
    • 3 Rev the motorcycle all the way to the red-line in first gear to pull the front of the motorcycle up into the air. This will not be a high or long wheelie, but is a great starting point. When you hit the red-line, pull in the clutch and shift to second. The front end will fall back down. Do not, for any reason, activate the front brake, while the front wheel is in the air, as this will cause the bike to crash upon contacting the pavement.
    Clutching Up
    • 4 Begin riding at a moderate pace in second or third gear. Be sure that you have plenty of space in front of you before beginning the execution of a "Clutch Up"
    • 5 Pull in the clutch as if to shift to the next gear but do not press the shift lever. Instead, rev the motorcycle by rolling back on the throttle smoothly and quickly. Let go of the clutch quickly (but as smoothly as possible) and lean forward to offset the power of the motorcycle.
    • 6 Repeat this maneuver multiple times to get comfortable with the motions. The front of the motorcycle may hop only slightly until you figure out the right amount of throttle and clutch to give the engine. Remember to never hit the front brake with the wheel in the air.
    • 7 Perform a proper wheelie by pulling in the clutch, revving the engine, leaning forward slightly and then dropping the clutch. Be sure to cover the rear brake with your right foot as it will keep the motorcycle from flipping if you give it too much gas.
    • 8 Hold the throttle at a steady position to keep the front wheel in the air. Bring the front wheel back down by pulling in the clutch or pressing softly on the rear brake.

NO ELECTRICAL POWER TO BIKE


Keith, if you don't already have a solution, let me suggest you check the battery leads. I recently( April 28) had the same problem. A good samaritan told me to check the the negative battery terminal. He was correct, the bolt connecting the negative battery leads to the battery was loose. After tightening, bike started. Norm

How to drive?


you can ride the cluthch on a bike un like a car you wont hurt it its oil lubricated constantly, sitting on the bike pull the clutch in with your left hand and click the left foot lever down in to 1st, then learn how to click it back up 1 half movement in to neutral. the neutral light will come on sfter the bike enters neutral. in first gear give the throttle on the right hand a squeeze and pull the clutch in with your left hand put foot gear selector down in to 1 st and begin to release clutch slowly. hold on as bike will engage may be jerky balance yourself! when you get moving stop! by pulling the clutch in and the hand brake as you close the throttle to stop! practice your take off many times some where safe! when you get your balance in 1st gear pick up speed and begin shifting the foot gear selector up in to 2nd gear and practice closing the throttle and breaking to a safe stop. gears are generslly 1st down 1 click 2345 and6th all up from there and neutral is 1 half a click up from 1st between 2nd gear. And dont put it in gear with the kick stand down t may stall on you

hope this helps

Hi,i own a dinli t-rex dl-601 100cc atv quad bike and i recently changed the v-belt,cleaned the carb,wahed filters,drained and changed engine oil,drained and changed petrol,drained and changed 2 stroke,...


I think you might want to change catagories, I found this under Bicycles. Also, I was curious as to how you can list it as a Quad Bike . . . Bike is a short term for Bicycle, Bi meaning 2 as in 2 wheels.

Honda CR125 Motocross bike throttle delay


ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side or bottom 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. Now pull the top cap off the throat of the carb and remove the large slide. There will be a long needle in the center of the slide. Remove the needle and then move the clip at the top on the needle down one notch. Two notches may be required but start with one notch. Put it all back together and try it out. Moving the clip downward richens the low end fuel mix.

Honda cb750 f2 1978fault on old bike ! electrical problem


From your explanation it sure sounds electricals, but surprising to hve a total failure to the electricals and thn it reappears after 30seconds!
Best would be to go through the wiring especially frm the battery onwards, the fuse box .
Since it is totally disappearing it should be a fault to those main wires could be lose connections somewhere!.
Hope this helps.

Few questions from a new owner


and I absolutely love it (aside from the broken headlight!) but I was wondering what the deal was with the seeming variations of paint finishes on the Military bikes? Mine and many others that I see have the flat olive drab finish, while there are others that I see with a very glossy finish, and in some cases, pinstripes. What's the deal with the variances -- are the glossy finishes and pinstripes the result of custom modifications? Also -- huge problem while riding. I know she's a brand-new bike (only 25 miles) so there are probably some break-in kinks that need to be ridden out, but this bike dies on me all the time. Unless I'm CONSTANTLY giving the bike throttle, it'll just die. Whenever I go to stop at a stop sign and am in first gear, the moment that throttle is let go, the bike just dies. It seems like I have to constantly pull the throttle on the bike to keep her running, it just does NOT want to idle. Also been noticing some small problems in shifting -- never seems to shift as smooth as other bikes I've been on, and I'm not sure if this is because it's a brand-new bike, or just older technology -- I'm totally new to all of this so I'm really not sure. Any ideas?,The shifting gets smother within 1000 miles, I have 1300 miles and rarely have any false neutrals or as clunky shift problems any more. Like Scotty said give the throttle screw a turn to increase idle( should turn by hand located on the carburetor). I did have a loose carburetor to cylinder head(jug) rubber boot loosen on me and was leaking air making the idle rough on my bike .After I repositioned the boot back on and tighten the clamp at the carburetor I never had the problem return.,,,
