1984 fxst softtail bearings how to install new ones,would like to see picture or get instructions on what to do.

Possibly a dirty kill switch contact.

You need to loosen the front lower motor mount. I believe it's an 11/16 nut on the very bottom. Loosen that. Once you've done that then loosen the 2 other bolts that hold it in. It should give you enough clearance to get the rear rocker in.

I would check the ground at both ends check your battery power wire also the plug that goes into the starter relay and you may just get a new relay or swap with known good relay last I would check the starter button on the handle bar you really checking for clean connections that's what I would do,, best of luck ,,

You got one of those fancy spring loaded caps? If you do then it's gonna "pop off" if you don't get it fully tightened...Just when you THINK it's tight, you need another 1/4 round to fully seat it. Seen these caps blow off lots of times. Oily pants caused a few bikes to get traded in even, lol.
Don't forget, oil expands, and most everyone i know runs their oil level 1/2-1 inch low on a cold engine...the older glides with the horseshoe tank always gain oil after you ride a few miles.
I hope this helps.

The turn signals you have bought are complete with running lights. This is mandatory in most American states. You only need to wire the Red and The Black leads to make the indicators work. (Unless you are in America).

This might be of some help

30 psi front
36 psi rear (single rider)
40 psi rear (dual riders)

I have a 98 softail and the mirrors just unscrew using an open end wrench. Also use the blue loctite when reinstalling for vibration.
