What fork oil.
What fork oil.
For all you guys with lowered bikes, what fork oil are you running? I have developed a clunk in the front end. I thought it was the neck bearing, had the dealership address that issue. They also replaced my fork oil with type e during that service. my clunk has gotten more frequent when hitting bumps. Only thing I can figure is the weaker fork oil is not heavy enough. I ran the SE heavy fork oil in the scoot when I first lowered it and didn't notice the clunk. What do you all think?

i still use the Type E in mine with RaceTech Gold Valves and 1" spacers to bring the front end down a bit, haven't had any issues.. but it's pretty cheap to change the fluids, so if you think it'll help, do it up.

I finally gave up and got away from springs and oil. Gas monotubes, 1 of the best things I did for the bike. I no longer deal with "wandering", brake dive and I get a more firm handling front end. I also notice that when I put a passenger on the back I get no variation in how the bike handles and rides. With the Shotgun I don't think you can beat that combination, IMHO.

If you don't have the dampening valves, like the Sgt_Jim has, the heavier oil will dull down the clunks.

I thought you still needed oil for monotubes?

If I lowered my front end, I would definitely bump it back up the the S/E Heavy fork oil. We did that to my buddy's lowered '09 Fat Boy and he had no issues at all with the clunk. I road the bike and was pretty impressed with the ride, especially given the ease in which you could spray floorboard sparks on a lowered motorcycle.

I also use the Race Tech springs and Gold Valves in my lowered front end. I added PJ 15 wt ForkTuner oil. Works very well, no clunks. I think the rebound could be a bit slower, so I may try the 20 wt.
