I have a 2009 Harley Sportster 1200XL Custom. When I have the clutch fully pressed in it sounds like the starter is engaging and there is a grinding and whining noise coming from the primary. This is happening every time when changing gears as soon as I pull the clutch in, but it also happens intermittently while at a stop light with the clutch pulled in.
I have read a log of forum threads of others experiencing similar issues. I kept seeing it could be the starter relay, so I replaced that but it's still happening. Now a new issue is happening and the bike will start without pressing the start button. I can just flip the kill switch to run and it will start without pressing the start button.
I'm thinking it is either the start button or the starter solenoid but was hoping I could get some advice. I did remove the controls housing on the handle bar for the start button and it appears clean/dry. I have heard some say to put WD-40 on the button but wanted to hold off and see if I can get some advice on this specific issue first.
After I replaced the starter relay I went for a quick ride around the block and it seemed like it was fixed. I stopped in a parking lot and it happened again so I pulled my phone out to record the noise. Here is a video of it happening
Replacing an electrical relay will not stop a noise. Noise is from a mechanical issue. Squirting WD-40 on switches will be the same results as replacing the starter relay. It's a 2009 with how many miles on it? Late model Sportsters have the infamous disintegrating riveted spring plates in them. Pull the primary, take the clutch apart and inspect the riveted plates. It's a really SMART IDEA to get a Factory Service Manual, READ IT and gain some knowledge about yer bike.
