What oil is recomended for my 2000 Night Train?

A red light on in the clock usually means over charging. You cannot reset it. It will go off when the fault is rectified. Go into diagnostics and post the results to get more help. If it is on the dash, then you have no oil pressure. Do not run engine this is checked out.

once a vehicle has been serviced with synthetic oil your not suppose to ever use any other oil. My opinion would be to drain the oil again and change the seal on the jug where it leaks as soon as possible and add synthetic oil. also make sure the mechanic you have your Harley serviced at is aware of this or your bike will get messed up fast. Is this the knight train limited edition that came out with air suspension? If so badass!!!

Ignition leads. They do break down over time and so maybe if you simply replace them you'll solve the problem.

It probably isn't oil, it's more than likely fuel mixed with carbon due to running too rich. check your settings on the fuel pak.

sounds like the starter solonoid is bad.

You will need approx.8 to 9 ounces in each tube if they are still wet.If they are dry complete capacity is 10 ounces.I hope this helps.
