I bought an 09 Road King Police last year with a stock 103, It had 8,000 miles when I got it and has 21,000 now after a couple of rides (ha ha). It's run great even when pushed a tad bit (ha ha again). I've had no problems at all, just did the scheduled service every 5,000 miles and had to get a set of tires. Brakes still have pad life but I'll probably change them out at the 25,000mile service. I haven't made any internal changes (like cams) but did go with a Screamin' Eagle air box/cleaner, bassani 2 into 1 exhaust and had it properly mapped/tuned at the HD dealer.

My question goes out to you that have had a 103 a lot longer than me. How many miles do you have on yours, have there been problems and if so what kind?

 

IMO the 103 is a tried a true engine. H-D 1st put them in the CVO & Police models which is one of the main reasons I bought my Ultra Limited. I put 16,000 on it this year
The cop bikes take a beating chasing speeders for the few years they are in public service. and keep on running. I figure that is why Harley put them in the CVO line-up.
Are you planning on changing the cam at some point? With the other mods she should really come alive.

 

I have a 103 with 30,000 on it.Replaced the clutch basket because of a bad ring gear {07 model}.while I was in their replaced the compensator..That is about the only trouble I have had out of it..

 

+1 I agree 100%!! That's the reason I decided on a 103" build over a 107"... "tried & true". Also agree, cams would really wake your bike up!

 

I have over 27K on my 103 stage V build.

 

When I make decisions sometimes I question myself weather or not it was the right one. I have a 2011 SG with the 103 cruise and abs. Its still stock and I think its damn fast as it stands stock. This is one post I like to read proudly. Lets me know I made the right decision

 

Wouldn't own anything but a 103. My 2010Ultra has 13k since last March and my Street Glide, which was bored from a 96 to a 103 has 34k on it.

 

The reason I went with an '09 FLHP was the engine, no regrets here.

 

Wow guys, I thought it already had kick. The only thing I thought was a little strange is top speed. My riding partners have a 03 Road King Classic 88 and a 09 Street Glide 96, both with stage one kits. I can do 108 mph (but get there faster) and they can get up to 106 and 108.

I know different cams do different things. What do I do to get a little more top speed without losing the quickness. Don't get me wrong, I hardly ever go over 80 unless I'm passing in a hurry or maybe a couple of times on a long trip see how fast it will go on a long straight away. I would like to at least go a little over an 88 or 96. Love the quickness though.

Any other engine mods that increase power, speed or longivity besides cams?

 

52k miles on my '08 Road glide with the 103" Big Bore Kit from HD. Bulletproof so far...
