I'm doing a lower fork leg changeout on my 02 Fat Boy and I'd like to know the fork oil capacity. When I change the oil in the future, without removing the legs, is there a different amount to use? Can I hand tighten the 6mm allen head bolt on the bottom of the slider and be content with that torque? Thanks

 

You need a manual. They all told me this when I got here too. I think that torquing by hand is fine but you will get a lot of disagreement regarding this subject. Manual says 12.9 OZ's. I would imagine it's the same as was in there. Some people say to use a heavier oil as it soaks up the bumps better.

 

anubisss, Thanks. I'm going to use 20w SE fork oil @ 12.9 oz. Stock front end. The 6mm allen bolts were nothing special to break loose by hand and I wouldn't have considered them loose, either. I'll have it back together today. aw

 

I'd snug the dampner bolts a little past hand tight. Granted they won't fall out because the axle will hold them in place but I don't think I'd want them loose.

 

*Finished* Replaced the type E (red) with 12.9oz/each SE Performance/Heavy (part# 99881-87) fork oil. Stock Springs. Front end feels nice and secure. Thanks!!!!!

 

Job Done !!!!!

 

Let's not forget Ace Hardware's chrome acorn nuts (5/16 x 18) with chrome lockwashers and flat washers. Also installed was chrome allen head fender bolts with chrome pop in covers, also from AH.

 

I gotta do this and was checking out my manual. I assume you pour the oil in the top of the fork? Just the kind of stupid question that I need to have answered.

 

anubisss, When you drain the oil, remove the fork tube caps and remove the drain screw. The caps are not under pressure and only serve as a fill hole. The caps have a rubber washer underneath them and I guess it's up to you to replace them. You can purchase the cooper washers for the drain screws individually if you go to HD. I replaced my drain screws with a chrome hex drain screw set with washers (HD # 45848-03) I removed my cap carefully with a large adjustable wrench. My fork oil seal rebuild kit came from Drag Specialties (James Gaskets part# JGI-45849-84) and my fork guide bushings came from HD (45940-84). The SE fork oil made my bike take on a new personality.
