Consider buying the HD electrical and service manuals.

Get yourself some electrical cleaner spray.
Look forward to your progress. Good luck.

 

@seniorsuperglideE8 I plan on getting the electric soon but at this moment I definitely feel more comfortable changing the fluids so I will tackle that next.

@Bumpandrun Most people tend to stay away from flood bikes/cars but all that means to me is there is less competition and I can get it for cheaper! I plan on working my way up to a car eventually.

@TroutBum I've found a few manuals online that I'm going to download but I'm not sure if they are just generic Sportster manuals or specific enough to use. I'm still looking through youtube for any videos that help but that is part of the reason I'm making the videos is so I can help others (and myself) in the future.

 

 

I'm thinking that bike might just start and run with a good battery!!
If you can get it started, fill the primary with whatever cheap oil, run it for 10 minutes, drain and refill with good oil.
I wouldn't do anything else to the primary in the drained oil is clean.
I had a flood vehicle some years ago. If the wheel bearings were under water they WILL fail in the future.
Mine were ok after the flood but it sat for 6 months and by then they were very noisy.
Same deal with the starter, take it apart, clean and lube it, it will be obvious if its been under water.

 

Any idea on how high the water was ? That could answer a lot of questions ...was there water marks on the bike ?

 

@Roadflyer I'm hoping it can be that easy! Once I get it running I will just ride around the neighborhood then drain primary, possibly open it up just to inspect and make sure there isn't corrosion, then refill.

@1957buick The water line was just to the bottom of the engine oil tank/ just under the air intake. If you watch the first video I posted I try to zoom in on the water line.

 

I think you have a winner there!!
If you have the primary off, check out the starter, it would have been under water.
Remove battery connections first, that starter drive can take off fingers.
I like a good repair project, especially ones with happy endings.

Take a hard look at your left side swing arms in the back at that transition line weld. I am guessing that is probably just a crack in the power coat but usually, it's way tough. And that area that looks like a crack should be the strongest part. Usually, a crack in the coating would be at edges of weld.
