Fork Oil Recommendations

1985 FXR

Did a bunch of searching but haven't found enough answers. I like pretty stiff front ends. I really dislike fork dive and all that. I am thinking some 15 weight is about right. I also need to know how much. This will be a brand new 35mm front end with fork tubes about 25 3/8 (2" over from MOST 23" FXR's). My manual says 85 FXRS's take 5 Fl oz and FXRT's take 7 1/4. Well mine has the 2" over forks, dual disk and all of that jazz. How much and what weight do you recommend? Any brand favorites? I usually run Redline in all of my bikes.

I should mention I am running progressive springs with 2" spacers.

Thank you!

15 w will be stiff for sure... Quantity should be in the install guide I'd think.

Check the progressive site.
Can't remember the measurement, but you colapse the fork tube and measure from the top of the oil to the top of the fork tube, progressive has it.....

Will have to look into it. Never rebuilt forks and don't want too put too much or too little.

Don't see much on the progressive site.

Looks like about 7 oz, but my forks are the 25 3/8. Maybe just put in 7 and see how they feel.

5 inches keep coming to mind for some reason, but I'll have to check from some of my paper work.
Sorry for not much help but I measure out, then put that back in.
I have to look it up any how due to I have a raked triple tree/extended fork thing going on this winter, so I need to find out too.

JustDave71 wants to know where he is and how he got here
cartridge or valve internals and 10 to 15W Bel-Ray.

Pretty much impossible to kill dive with stock spring config in my experience.

Picked up some Bel Ray 15W. That's all that was at the local shop. I guess I'm going to put in about 7 ounces, test ride it and then pour 1/4 ounce in at a time from there.
