Nightster Front Fork Seals
How do you tell if your front fork seals are bad? I was riding my nightster and was unable to hit a gigantic pot hole.
Now it seems my socks don't rebound and sag much further than before. I pulled up the boots and there was not any sign of fluid.
When I am not sitting on the bike, the forks seem to fully extend. When I sit on it, the compress almost the enitre amount
Thanks for your help!

Best I can say is go to a dealer and sit on another bike and compare, make sure it's just not in your head. And if it still looks like your forks are sitting way too low, have the dealer fix it under warranty, just don't mention the fact you hit a big pot hole. Also as far as I know the internal springs are what determine the height of the forks, the fluid just controls the dampening effect and even if you blow a seal, the bike should only get bouncier, not lower.

I started a post a few days ago about this same exact problem. I got an appointment on the 18th to get em looked at, hopefully if there is a problem they will fix it under warranty.

Definately but my appointment isn't till the 19th (thought it was the 18th) but def. will post the outcome. If there is a problem I am willing to bet $$$ they say it is my fault and warranty won't cover it. I'm not mentioning names but lets say I haven't had good luck with this dealership.

You should have play in the front forks sitting on it and if you push forward the forks should decompress and come back up as you take weight of the front end.
The only way I know of to actually check fork oil is to drain it - it's not hard but you would need to fill it again. Let the dealer do it for you - it's their problem since your bike is new.

Spoke to a tech today. He recomended changing the fork oil to screaming eagle, which is supposed to be a little heavier duty. I have an appointment on the 13th, to have my 1000 mile service and get the fork oil changed. I will post the outcome.
