True but in my opinion they are much faster and easier to check and adjust and as previously stated MUCH cheaper to replace and can be fixed or replaced on the side of the road with minimal tools.

Only if you can't turn your on wrenches, and even then your talking 75K - 100K miles between replacement under normal conditions. The belt is in the range of $175 - $200.

The Kevlar belts for all practical purposes, don't really stretch much after the first 1,000 miles, and I've never found it necessary to readjust the belt tension other than when I replace the rear tire every 14-15K miles.

We're talking about tension and adjustments, not issues. Also, you don't have to adjust that chain? Yep you do. You also have to lube it. Yep.

The 2010 FXD shop manual says: (with 10 lbs side force)

With motorcycle on jiffy stand w/o rider or luggage 1/4" to 5/16"

With Vehicle upright with rear wheel in air 5/16" to 3/8"

Hence my belt drive tensioning paranoia....those are very tight tolerances (for a flexible belt)....and the manual specifically mentions that most belts are under-tensioned, which can significantly shorten belt life.

You could go crazy trying to get a belt tensioned within the 1/16" slot between the upper limit and lower limit. I can't imagine a dealership mechanic worrying about this kind of precision for a drive belt. Even with the tensioning tool the measurement is pretty subjective.

Curious cHarley, what tire are you using that gives you that amount of mileage? My rear tire only lasts 8-10k!

dont be to scared of it,give it a half turn at a time,count the threads showing so you no were you are at present
,mark one of the flats on the bolt head so you no were half or full turns are,and do the same to both sides.
in centre of belt you should be able to twist it to 45 degrees,more then that to loose,less to tight!

The last 2 were Metz 880's, currently giving the E3 a try. Yep, the stock Dunlops only went 10K for me also.
