Default high mileage

Assuming its well maintained what is the average engine life on a Twin Cam? I am at just under 30000 miles and starting to wonder.

I've seen many over 150,000 and still running great. I have near 80,000 on mine without any issues.

i have several with 90,000+ that come through my shop. degree of maintenence and modification will affect the outcome. properly assembled and good choices for combo's with a good tech will assure long life, as long as you don;t ride like a bonehead.

78,000 and still ticking. This bike has been great. Put in Wood lifters at 40,000 as a precaution

I just turned 30,000 on my 2002 Fat Boy. I have been nervous for a while about the cam chain adjuster shoes so I broke down and pulled it apart. I wanted to send the wheels to the powder coater anyway. The adjuster shoes were worn badly. The pins in the links were showing about half exposed the chain was worn into the shoe that far. No failure yet, but obviously not real far off. Very simple job if you are mechanically inclined. I never priced it through a shop since I am a mechanic by trade, but I bet it isn't too bad to have it done. I would say it is well worth checking after seeing what mine looked like. Cheap insurance.

It has been a great bike. Haven't had a single problem with it. I talked to a guy that had 90 something thousand on his and other than chain adjusters he said he hadn't done anything. Seen several with 50K plus on them.

I have it on good authority from Darkhorse that the rods are good for about 150K. I'm sure there are lightly used bikes out there with 200K but I trust their judgement and information.

Of course there's other concerns earlier than that, specifically the cam chain tensioners, which have been known to go south around 20K, and the inner cam bearings (switch to Torrington's), but other than those you should be good for 100K easy with routine maintenance.

Bought my 2003 in 2007 or 08 with 31,000 on it. At 85K, I noticed some oil usage and wanted the 95" SE motor bumped up to a 98". Ended up 107".

The 64K from when I bought it used to the rebuild were fairly hard miles and shockingly, still had the original cam tensioners in there. Lucky, probably, but they were checked at 40 and 60K.
