Installed chrome sliders on my RK Custom today and now the front end is bottoming out over bumps. I put the amount of fork oil specified by the Service Manual (11.1 ozs. Harley Type E ) Any ideas?

 

Mix equal amounts of E and SE heavy or just buy a heavier weight oil

 

Is it bottoming out, shocks going all the way down? or when you hit a bump is it just hitting hard? When I did mine I put just a little to much oil in and it was like having a rigid front end. So I drained the oil and put the right amount in, I had to double check. I put my wifes new measuring cup on a nice flat surface and made sure I had 11.1 oz. The bike was fine after that, it doesn't take much to get that hard ride, I think I was only over .3 like 11.4 oz. Hope this helps.

 

If all you did was change out to chrome sliders then it should ride the same! Are you sure you assembled everything correctly? Did you make sure the "BOTTOMING CONES" are on the end of the damper rod and the bolt went through them?

 

I boughteverything all ready assembled. All I did was add 11.1 ozs. of oil. The front end would actually bottom out and clang. I could push down on the front end and there was little to no rebound. I have sense added3 more ozs. of oil to each side. It no longer bottoms out, but is a little stiff now. Why would I have to add that much more oil to stiffenup the front end?

 

If you add too much fluid you risk blowing out the seals.

I would take them apart again and make sure everything looks good inside of them. Fill them with the 11.1oz of SE fork oil, and put it all back together.

Aftermarket or ebay? You better pull them off and apart to make sure they are complete. Something IS NOT correct!
