I have a RH Sport that I just upgraded to a Malosi 70cc kit and new yellow spring variator kit with a new primary jet and cooler plug. I love the new found power. What I'm struggling with is the poor front fork performance. I'm about to put in 25W fork oil to see if it helps.
I'm wondering what modifications people have done to improve the fork performance. I find it diving and not having much damping or rebound.
I'm considering pulling the legs apart and weld up one of the orifices to see if it slows down the damping and maybe helps with sag
Thoughts and DIY project info is welcome..

I don't know what the oil spec is on a RH. You might do better by pulling the springs and measuring the oil height from the top of the tube with the springs out & fork compressed. Maybe fill a little higher, but not too much. If the oil height is too high then the "air spring" effect will increase internal pressure under fork compression to the point where the fork seals blow out.tomg wrote:Thanks.. I'll try the spring stacks in addition to the 25W oil. Any idea on what the CC/leg on the oil? If not, I'll just measure what I take out
If the RH forks are anything like the Rat, then you may need a strap wrench to keep the fork tube from turning when you remove the fork cap. Remember to loosen the top pinch bolts first.
