Fork Oil???

Hey guys i want to change my fork oil but i dont have a center stand or paddock stands or anything like that so im most likely going to take it to the shop. But heres the thing, i want something thats going to be able to withstand the terrible road conditions of the city and something that will last a long time so what kind of oil should i get. Also if this should include changing the forks springs what do yall recommend. its more likely then not that im hitting 3 inch pot holes at least on a more then daily basis.

Any feedback input and 2 cents are all more then appreciated

thanks guys

I use Bel-Ray 15W fork oil in mine combined with a Race Tech .95kg spring and F4i forks

race stands or center stand wouldn't help when changing the fork oil anyway. you need to suspend the front of the bike. I hung my from the roof of my garage using my tie down straps and some heavy duty eye hooks from home depot.

So you're saying you want a more compliant suspension over rough surface. What's the nature of the problem? are you bottoming out? or is it too jarring, i.e. not compressing enough?

How old is your bike? Sounds like you just need to adjust them a little bit.

The key to getting the 919 forks to act right is put as light of weight oil as you can without bottoming out. Also get some after market springs if you weigh more than 150 lbs. You want to be able to use almost all of the fork travel for the most aggressive riding you do. Heavy oil makes the valving slower and more harsh. The valving is what keeps the contact on the road.

I'm running stock springs and i weigh 220. generally the pavement i ride on is not as rough as what you're describing. I know there have been spring discussions on here before, try searching. I believe the race tech springs are slightly longer than stock and will raise the front end up a little. Experimenting with oil can be time consuming. Here's what i would try if i were in your shoes, in order:
  1. Adjust riding style... less weight on the hands and use your legs more...
    especially when you're hitting the rough pavement. My tank has two shiny spots on the flat black paint where i often squeeze the tank with my legs
  2. Try a spring that will give the front a little more travel with stock oil... the stock oil is pretty light already IMO.
  3. try lighter oil with the aftermarket spring.
