Bali 250cc Help!

[merk1106]

Hi everyone! I'm new to this site, but have enjoyed reading the threads. I received a 2007 Bali 250cc today and finally got it all assembled (with some help from more a more mechanically capable friend than I ). He took off once it was put together minus the battery, as that would take some time to charge. Well, I got the battery charged and installed. Put gas in. Started it up after several attempts. Adjusted the idle. Now the problem I'm having and hope that someone can shed some light on is when I twist the throttle slightly, the engine cuts off. I turn it back on and it runs fine until the throttle is turned, then it shuts off again. I have adjusted the choke and idle but the problem is still occuring. If you have any advice that can get me scootin' faster, it would be greatly appreciated!

Another thing...Whenever the throttle is twisted and before it stalls out, it doesn't feel like the gears are engaged as the bike has no forward movement. I hope I am explaining this clearly.

Hi Merk1106

Welcome to the dog pound!! This is a great place to get info. I have a Bali 250 also, about 38 days old so I have used this site allot to get some great help!

Couple thing to check that I noticed on mine but I did not have the same issue of cutting out. The Vacuum fuel pump was mount on the Scooter frame in reverse order with just one screw, which looks like it could have been been pinching off the fuel lines or the vacuum line.

Does it idle OK without cutting out? When you have it on the shop stand with the back wheel up off the ground and turn the throttle, does the back wheel start to spin?

I am sure you will hear from others. Let us know what you find out.

It's not a real great idea to leave the battery out of the charging/ignition system.
Most manufactures who's ignitions and charging systems are cdi type specifically state
do not run the engine with out a battery in line, you could damage the electrical system.
Hopefully you did not. Good luck enjoy.

Ok. I think I figured out the problem. I put a small amount of old gas in the tank in my excitement to get scootin'. I put in a full tank of premium gas and was able to get it moving. Next silly question: What type of brake fluid do these scooters use? The owner's manual states DOT 3, but every scooter site I could find recommends DOT 4. Since the mishap with the gas happened, I don't want to put the wrong stuff in. The right brake is spongy and my friend will be back in town to help bleed the brakes. He said I would need to get some brake fluid. Thanks!

My Manual says DOT 4. Does your brake fluid levels in your peep glass look low? They are located on the steering column just below the brake fluid reservoirs.

DOT 3 is OK but DOT 4 is better. When bleeding the brakes and putting in new fluid, be careful to not let the master cylinder reservoirs go empty. As fluid is drained out from the nipple below, keep adding new fluid to the reservoir.

If the front brake still feels a little spongy after bleeding, it may be that the "ABS" unit needs adjustment. On the bottom of the ABS unit is a cap that will screw off. Remove it and you will see an allen set screw up inside. Use your allen wrench turn that screw 1/4 to 1/2 turn tighter, then check the brake response. With the ABS unit in place, the front brake often is slightly softer in feel because the unit has a dampening diaphragm in it to soften quick jabs on the lever. In theory, it reduces the chance of wheel lockup but only slightly since it is not electronically controlled. It is still possible to lock up the front brake.
