There are usually two reasons why a battery will not stay charged after of course changing the battery.the most common cause is a faulty regulator/rectifier this electrical component regulates the voltage from the generator to around 12.8 - 14.4 volts ,it also rectified the current from ac to dc so it can charge the battery.the other reason is a faulty (usually burnt out) generator .I would try and borrow or buy n.a. regulator 1st as its the cheaper option.you can test the yellow wires from the generator with a ohms meter it should measure the same resistance between all the yellows if it's ok.good luck

    before you do any of this check across the battery terminals with a multi meter on -20 volts dc with the engine Running with a charged battery at about 3000 rpm.it should be as i said between in my first answer

Check with a multmeter if the two poles generator gives the required voltage must be no less than 12.8-13.0 volts at increasing speed and includes stop lights and headlamp reach values do13.8-15.0 volts maximum.If give more than 15,0 volts or small than 12.5 change relay rectifier.

SOURCE: starting 2007 kawasaki klx 250

• The first thing to do with ANY engine that has sat for any longer than a couple of months is to dump ALL the fuel in the tank and carb(s). ALL OF IT !! You'll want to refill with some high priced fuel that has fuel system cleaners (Like Chevron with Techron) not becasue you need high-test fuel, but because you need the cleaners. It's ether that or disassemble the carbs and clean out jets you can't find much less see. Your choice. The carb kits alone will cost you about $50 so a tank of high-test is looking pretty good, huh?

• Now the fact that you tried to crank the engine with old fuel has fouled the sparkplugs. All of them. Go buy all new sparkplugs.

• If your bike has a vacuum fuel valve, then you'll also need to set the valve to "Prime".

SOURCE: KLX 250 won't fire - new battery

-check the fuse right hand side below the fuel tank and seat, see if it is blown.
- Check to see if plug has spark, replace if necessary .
- Did you run the bike with a low battery before replacing it? could be that your stator is shot.
-Is bike trying to start but won't?

SOURCE: i have a klx 250s

Yes, there will be additional power. There is one problem to consider. Chances are the starter may not perform well at trying to turn the engine over against the added 50cc compression. Check with other big bore owners. An alternative would be staying at 250cc and getting a race cam. The cam would out power the bore kit by far. You just remove the current cam and send it to a company in California and they alter your cam for racing. This is what the pros do. Check it out on the website below. www.webcamshafts.com Neither you or I can give them degree angles for rise or duration or any other spec they may need, so you just need to tell them what type of racing you do (street, track, quarter mile etc ), and what you want from the cam; take off from the line, top end speed, torque, etc.. Basically, tell them you just want to wax anyone dumb enough to challenge you.

Im still breaking in my bike,,why is there a ticking sound in the engine while running?

All the parts in your engine are wearing in. Part of the 600 mile check up involves adjusting the valves and the cam chain tensioner (if it is not self adjusting). Chances are the valves are wearing in, the gap is too wide, and just need to be adjusted back to the correct clearance. Worst case scenario the cam chain tensioner has failed. http://www.kawasakiforums.com/forum/general-tech-9/klx-250s-2006-loud-clicking-sound-not-valve-33671/

Bought 2004 Kawasaki klx 125 and takes 20-30 kicks to start with choke on and even more when cold. Won't run right until motor warms up n takes a while for it to warm up. Runs fine after it does but it's...

Be certain the battery is in good condition. Install a new spark plug. Clean the carb and air filter. Use the throttle sparingly. The carb has a power valve that gives an extra shot of gas each time the throttle is twisted. Too many twists and the engine floods out. Please rate my answer. Thanks!

2007 Kawasaki KLX 250 transmission overhaul

Matthew, this is a bigger job than a "shade tree" or someone that is NOT VERY experienced. It can be complicated. Sometimes a transmission can be a tough fix! I would ONLY trust this is a factory trained professional!!! Sounds like you have considerable damage!!
