For U Solution

An erratically operating motorcycle engine signals problems with the combustion system. A sure-fire cause tends to be either poor performance or a misalignment of the carburetors when running a dual system. Flat slide and round slide carburetors cause the same bad engine operation; flat slide carburetors are just more sensitive and responsive. Syncing the carburetors correctly can solve some engine problems, smoothing out the fuel and air delivery to the engine.

Instructions

1

Use a screwdriver and crescent wrench to remove the motorcycle bodywork so you can access the flat slide carburetors easily. Pull or temporarily remove any hoses or electrical wiring in the way of your access as well.

2

Locate the idle-mixture fuel needle on both flat slide carburetors. Use a screwdriver to turn both needle screws in all the way -- turning to the right. Back the screws out with the screwdriver the correct number of turns on both carburetors consistent with the carburetor tuning providing in your motorcycle repair manual -- the number of turns varies by model. Confirm both flat slide carburetor needle screws are turned back out the same number of turns.

3

Check that the fuel supply is on and the fuel hoses are connected to both carburetors and turn on the motorcycle. Wait 5 minutes to allow the engine to get warm. Do not start pulling away on the throttle. Just let the engine idle. Attach the carburetor balancer tool to the carburetors.

4

Locate the throttle shaft shared by both carburetors. Twist the throttle shaft controls with a screwdriver so that the setting matches the readings displayed on the carburetor balancer tool. Pull the throttle a few times slightly while monitoring the readings on the balancer. Continue to adjust the shared throttle control while checking the balancer tool readings until each of the adjustments on the throttle control are matched.

5

Test the engine with some minor sustained throttle pulls on the throttle handle. Continue making adjustments until the engine cycles smooth out as it is running -- no burping, stalling or uncontrolled revving.

The slide hammer is a very specialized tool that has several different uses for repairing an automobile. This sliding weight tool can be used by a body repairman or someone pulling apart the inner workings of a wheel assembly.

Description

A slide hammer consists of a pole-like shaft and a donut-shaped weight that slides down the pole. At one end of the pole there is a round attachment which prevents the weight from sliding off the end of the tool. The other end of the slide hammer is the attachment end, where a threaded bolt and nut allows the tool to be connected with a rear axle seal or hooked into a damaged car body.

Rear Axle

Since a rear axle oil seal is pressure-fitted, replacing a bad one requires use of a specialized force. While one end of the slide hammer is used to grip the seal, the sliding weight is slammed hard against the other end of the tool. The donut end piece keeps the weight in place and after a few strong pulls on the weight, the part usually comes free.

Body repair

Instead of pulling apart the rear axle assembly, a slide hammer can be used to pull out dented or pushed-in body sections, like a fender or door panel. First a small hole must be made in the body part, but if the dented piece can be pulled back out to its original shape, then the workman can repair the damage without replacing body parts.
