Only drain oil on a warm bike as the Sportster's are a dry sump oil syste … m. I only hand tighten mine until I can not move it any further. Here below is a copy of what I wrote for another thread that will also let you do a quick check of the generator Here below is what I wrote some time ago on another thread. You should put in about 3 quarts 2. Check brake fluid reservoir levels and condition.
Usually when money is spent on a dyno, the bike is no longer stock. If you think something is wrong with it let me know and i can adjust if we agree and re-post, then hopefully when i get time i'll draw up a better version on my autocad and include factory wire colours. Place your oil filter wrench on the oil filter and turn it counter-clock-wise until it is loose enough to turn by hand. Once all of the oil has drained out replace the oil drain hose and tighten the worm clamp clock-wise 10. Pull on the top of the cover just under the edge of the seat , and it will open. I know nothing about wiring mine caught fire but Fe Head has posted on here about this diode several times, - only in relation to the solid state electronic regulators, I think, but am not clear on that.
On my '77 and '78 the left and right turn signal wiring is Grey with Violet and Brown tags on the wires. Check that harness connection for corroded, broken or loose connector pins, repair as necessary using a dab of dielectric grease. Orange wires always have 12 volts once the key is on. Still, I've had good luck using that site for Japanese parts that I've needed over the years. Place a towel or something over the master cylinder and the footpeg to avoid scratching the cover, and allow it to swing down.
When the generator's output voltage exceeds the residual battery voltage the diode no longer acts as the generator light's ground and the light does not glow. I'd adjust the tappets first. Insure that that it is going on correctly so you so not strip the threads on the oil pump. By running a bike for a few miles first, it puts all the oil back into the oil tank, therefore leaving a minimal amount in the case. Inspect brake pads and discs for wear.
If your bike doesn't have indicators. Lubricate the following: front brake hand lever, throttle control cables, throttle, clutch control cable and hand lever, jiffy stand. Now fill the oil tank with oil. Go to the left side of the bike, underneath there is a 90 degree bent rubber hose held on by a hose clamp. Start up the engine and insure that the oil check light turns off. The generator light works in series with a diode located in the headlight housing. Mark the breaker plate and take it out to check the advance unit.
The rear wires connect to a multi-pin connecter near the circuit breakers. For Solid State regulators they typically follow this pathway 1. Check tightness of all critical fasteners: hand controls, brake system, axle nuts, front fork components, riser and handle bar fasteners. It already make a nice scratch on the new front pipe, so I figure I'd just live with it. Keep watching for other replies. I hope this helps to explain the functioning of the generator light a little better for you if that is what you were initially concerned about. After looking for an eternity for an easy to read basic wiring diagram, i sat down last night and joined together the best of what i have found.
But that does not mean it was not there. Make sure the pivot pins for the flyweights is not worn out. A very simple schematic or any other help would be appreciated. When the ignition key is on and the engine is not running or the engine is running too slow so as the generator cannot add energy to the battery the higher voltage from the battery flows across the generator light through the diode to ground thereby making the generator light glow. Check tire pressure and inspect tread. Check and adjust drive belt.
When you … put the plug and cap back on and fill the oil tank, make sure that you remove any air in the hose with the plug. The actual horsepower number is just that. The last thing you want to do is reloosen the oil drain hose and let a little bit of oil run out. Check ignition timing and vacuum hose. This is located behind the clutch and under the swingarm. Make sure you tell me what year model you Sporty is and remind me of what you want. Is there a diode between the charge light and the A side of the generator? Maybe next time he comes along he can verify the situation with a mech regulator.
I have a fully coloured wiring diagram that includes the variations on the charging system if attachments are permitted. So thanx for doing the job the way it should have been done by the people who made the money off it and sharing with us. Just saw a bloke in my office who is our electrical drafting guru. Pick up an A 1N-4004 which is available at Radio Shack very cheap as it will work fine. Well guys, just finished wiring it all up this weekend and everything works great.
