Buying my first Big Dog 99 Pro Sport, it has less than 4000 miles on it ,what should I look out for with this bike?
Test rode it , great power , S+S motor , tranny a little tricky getting into neutral, how will the ethanol in the gas these days affect performance?
Any help would be great. Thanks..

As most will tell you on here, rev the bike just a little when shifting into neutral - this makes it easier. Wow, a 1999 with only 4,000 miles - sweet. Congrats on a nice find.

Welcome to the site, congrats on the purchase. People are great here!
I bought a '99 ProSport a year ago.
I had a short in the EHC and switched out to a Thunderheart.
Tank liner was desolving, had it stripped and relined.
Neutral, if idling need to be in first and bump the throttle as upshifting to neutral or if not running neutral is easier to find from first.
I hope you enjoy the ride.

Got some pics of that ProSport? On the neutral thing, after shut down in first, rock it forward in gear then it will shift to neutral pretty easily. The stock baker five speed has the "square" mesh teeth in the tranny and are very tight - its a racing set up with very tight and precise shifting. Someone could probably say that more technically correct but I think you'll get the drift. You will notice a very short clutch throw when you get after it. It's very quick.
 
good luck I have a 2000 ..1st thing only use 93 octain or better ... trust me ...keep the oil clean ....listen for noises ...I had major problems with mine just finished buttin new tor in .. originally had s&s 107 ... now optima 134.. much more power. anyway the reason I tell you is cause I just reacently this summer had to go through hell..if you got question shoot.. oh ya did you get service manual w it need copy ...

Welcome and enjoy your new Dog! Keep an eye out for peeling gas tank liner- I just went through that in mine (only had 3700 miles on it). the newer gasoline eats up the tank liner on early Dogs, the liner comes off in pieces and clogs up your fuel lines. Look in your tanks with a flashlight to see how the liner is doing- it WILL come off eventually so plan on getting the tanks professionally relined.

oh ya and don't sweat the clutch / neutral thing. fairly normal. just ride it and learn to work with it. Pretty much any racing oriented trans will do this- I'm used to it from owning a lot of sport bikes.

the hyden automatic primary chain tensioner will greatly improve the shifting.
Harley now makes a auto tensioner also. all newer Harleys have them. new Harleys do not have an inspection plate on the primary cover because there is no need to adjust it. great improvement on shifting into neutral with the bike running. also takes the lurching out at low speeds..

If you have a Baker 6sp trans you may run into issues with the auto-tensionser. I think this is due to the longer primary chain and larger comp sprocket, and it requires a larger slipper on the tensioner. Anyway just be sure to do your research before putting it in. I don't know this for fact just something I recall reading when I looked into using an adj. tensioner.
