It's a Harley. Notorious for hard neutral.
Take it to an experinced mechanic and do not pass go!
Change out the intake Gaskets and Carb. Gasket. You have a vacuum leak.
probably a bad spark, itll cause your engine to misfire flooding petrol in without igniting it, when it sparks afterwards it ignites causing a bang and backfire.
The most common cause is a grounded stator. Lack of primary oil or a too-tight chain can also cause excessive chaincase heat.
It could several things. Work from the spark plug, to the plug wire, to the coil until you find the culprit. If the coil is good then it could be the ignition module. The coil is the most likely problem but the plug or plug wire would be the preffered problem.
Yes, it could.
I would check the wire connections under the right side tank. I know on my 78 FLH I had that issue and it was the wire on the wiring block that was bad.
drive shaft could be out of balance or tires could be out of round
Yes. And unless you're made of money, Mobil 1 15W50 will work just as well as their V-twin specific 20W50 at a considerable savings. --- Some detractors will say auto oil containing moly will cause slip in the primary. Mobile 1 15W50 oil does not contain nearly enough moly to cause this to happen, and can be used in all three holes of your Harley Davidson with superior performance. Word of warning - Some service managers may use this as an excuse to void your warranty, so if your Harley is under warranty it is probably best to simply use Mobile 1 V-Twin 20W50.
I Have the same issue. Red Light on the speedo stays on. It seems to refer to an electrical problem. Ive discovered that my brake lights dont work sometimes. Could be the cause. Im off to HD today. 2012 Dyna FXDWG
No, all later model Harleys run on low octane fuel.
It sounds to me like the clutch adjustment isn't correct. If the cable is too tight, it will cause the bearing to spin continuosly causing it to wear out prematurely.
