Just bought my wife a 2002 Heritage.
I read here somewhere that pre-2006 they didn't have an easy pull, but I'm no wimp and it seems to be pretty stiff. Only 15,000 miles on the bike but it has sat around for a few years. Do you think it might just need some lube in the cable, replace the cable? Or is it known that the clutch on this year of bikes are harder to pull?
Going from 2002 OEM ramps, that are 21°, you can use the 2006 and up ramps that are 18°. They require less force to pull the clutch in. Considerable less expensive than Muller ramps.

Interesting, I'll definitely try that on my '98...however it looks like the ramp changes happened in 2000, not 2006 so the OP should already have the newer style on his 2002.

No the 21° ramps are discontinued. Part numbers below. When they went to the 'A' suffix they changed for all Twin Cams. When you look up parts online you only get the superseded part numbers. To get the original part numbers you have to have factory original period correct parts manuals. I have several years, but unfortunately not all of them.

Aha, thanks very much for clarifying that, I stand corrected, and now I know not to bother changing mine as they are already 18 degrees. . FWIW I did lube the cable and that helped a lot.
