Whereis my speed sensor on my 2000 883 xlh sportster

SOURCE: starter not always turning motor

Possible solution. You probably know that harleys, unlike almost all the others used a bendix type to shove the starter motor's gears into engagement with the starter clutch. Since you replace the solenoid, the thing that pushes the gears into engagement; the battery, that would push the starter motor if the gears were in engaagement; and the starter motor, which would turn the ring gear if it was in engagement. So wht's left? Unfortunately it sound like it might be the teeth on either the ring gear or the bendix gear, probably the ring gear as it was notoriously weak on iron sportys. Not a problem you want to try to fix at home unless blessed with tools, room and time.

 You either need to lube the cables, or adjust them. You adjust the throttle to have a 16th to an 8th inch of freeplay with the bars like youre riding straight. You adjust the snap back with the bars fully to the right. As far as the motor shutting off , you need to use the enrichner ( they call it a choke) until it will idle on its own without rapping the throttle.  Also , your idle may be set too low on the carb. The adjustment is made at the idle speed screw , right behind the air cleaner. 

SOURCE: Can anyone help me find a wiring diagram for a 73

Most Ironhead sprotsters were pretty close as to the wiring. If you'll contact me directly, I'll scan a diagram for a '79 in and send it to you. Contact me directly at wd4ity at bellsouth.net. Good Luck, Steve

"Backfiring" is a pretty broad term depending on where you live. Some people refer to backfiring as popping from the exhaust while others refer to it as the engine spitting through the carburetor.

I'll assume that you're talking about popping out the exhaust pipe. If it does this after you rev the engine and it backfires on the way back down to idle, this is typical of an exhaust system sucking air. The mixture is extremely rich under these circumstances and will not ignite. But, if your exhaust system is sucking air, it combines with the fuel air mixture already there and bring it to an explosive mixture thus the backfire.

You can check you valves but I've always found that if the valves on an Ironhead are too tight, it's extremely difficult to get it started due to the low compression on that cylinder.

Check you ignition timing and points setting. Also, what kind of condition is your mechanical advance in the distributor in? I'm assuming this is an XLH model and not the magneto equipped XLCH.

What type of carburetor is on the engine? Hopefully not the original Tillotson that it came with. If it's an S&S, the low jet should be a 28 and the main jet a 66 to 70.
