I purchased a 98 Dyna last year the bike has 25,000 miles on it because the bike is too old for Harley too work on it I decided to do a 20,000 maintenance myself this is the first bike i have owned so i purchased a service manual and watched internet videos. I have changed all the fluids replaced the clutch cable replaced the front and rear motor mounts and now because tires off put new wheel bearings in them swing arm off to repack bearings i have decided to replace rear belt which looks alright but might be original and don't wanna take a chance on it breaking during a long trip. My question is there any else that i should check or replace now that i have gone this far with primary off new sprockets ? main drive seal ? transmission seal ? I would appreciate any advice from bikers who have much more experience working on their bikes than i have

 

Sounds like a good start for baselining. I'd consider the carb and fuel system (line, petcock screen & diaphragm, vent,..maybe tank...rust/sediment), steering stem bearing repack, bleed/flush brakes.

I worry about any fuel system rubber at that age. My experience is that oil seals hold up pretty good, but the EVO guys would know better about their idiosyncrasies.

 

+1 On the Above ..

 

Be sure to check / pack the new wheel bearings - most (like all) are lacking adequate grease
