Hello from Orlando Florida

I just picked up a 2002 fat boy that has fuel injection and I don’t know anything about them, years ago I had a crotch rocket so I do know how to ride and shift the gears. I would like to change the oils and give to a tuneup. Even though it runs great it does some times lightly backfires going from first to Second.
How much would it run to change all three oils
Thanks for any help
 
Welcome to HDT from Gulf Coast AL
So you are doing it yourself, you will need 4 qt oil for engine ~ $9 ea for full syn, 1 qt for primary, and you can run syn in the trans but I would recommend Redline Shockproof ~ $12 per qt on line. So ~ $57 for the liquids another $15 or so for oil filter and you should change out the o rings on the drain plug. New gasket for the primary $20. So around $90. You may be able to get stuff cheaper if you don't use syn, these are HD dealer prices.
The backfire could be an exhaust leak, check when its cold all connections loosen and re-tighten, don't over-torque. Removed and clean the spark plugs. That might about do it but its possible I left something out.(disclaimer lol)
