How do I determine if a used Sportster engine is good or bad?

 

How it Starts, How it Runs, Check for Leaks, Watch Exhaust, Check Overall Appearance.. Usually One that Keeps his Bike Looking Decent Externally also Cares about the Internals as well..

 

+1 - and ask for the maintenance records. Someone that doesn't have/keep detailed records, probably wasn't very diligent about doing the required services.

 

All of the above!

 

Yes indeed all the above and Dude, ride it. If it pulls like a tractor - it's a good'n.

 

Oh and this is just one opinion but look for a 1200 not an 883. Tested both myself, there's just no comparison. I knew I'd be wantin' the 1200 after a month on the 883.

 

exemexer is right on. Bought my 883 and loved it but ended up with a 1200 after one month due to a friend selling it. Now the 883 sits under a bike cover and a for sale add on line. Test rode larger bikes such as the Dyna, Softail, ect but nothing comes close to the 1200 for me. Just my opinion.
