'99 and 30k. Still runs strong.

 

07 1200R bought in July 09 with a little over 6,000 miles on it, just rolled 25,000 + last month. Mostly all highway and interstate miles. No serious issues.

 

2002 - 1200 20,000 miles

 

No enough yet! '08 XL1200C--~10,000 mis. Rocker cover gasket leak fixed by dealer under "Certified pre-owned" warranty. Other than that, routine maintenance.

 

this concerns me that so many of you have had Rocker cover gasket leaks since I have a 2006 with 2400 miles. Is this the same thing as the valve cover gaskets?? These are cheap/easy to fix right? I notice that the chrome push rod tubes on the right side on mine usually have a very small about of oil on them buts that nothing. I've only had this bike for 3 weeks so I cant say much

 

2700 miles since the 1st part of July on a 2009 carry over Nightster.

 

99 with 33000. No major issues.

 

Not enough, 2006 1200 custom 16,000.

 

03 just turned 30,000

 

This isn't exactly an answer to your question, but might provide a little more about engine longevity.

My 06 has about 82,000 miles. However, the first 65,000 were with the 883 engine. I couldn't believe how clean the engine was on the inside. It looked like a brand new engine. I wouldn't hesitate to put that engine back on the bike, and ride it another 65,000 miles.
