Yo.
I have a 2001 F4i and have never replaced the fork oil. I have around 15K miles on the bike. How often does this need to be replaced? What about the rear shock?

I have a service manual. How hard is this to do myself? Is it worth taking in the forks to a shop? How long does it actually take?

Thanks,
Zac

 

There's a tutorial on BARF for changing fork valves. If you're just doing the front oil, you wouldn't need the whole tutorial. Sorry I don't have the link on my work PC.

As far as rear shock, I don't think they are serviceable but someone can correct me.

Fork oil should be replaced annually or every 2 years for street riders.

 

rear shock is serviceable...removing it is a pita.

shop will charge you dearly for replacing the front fork fluid.

 

when you service em. send em off to racetech. they can modify theforks and shock springs and valving so they actually work for your weight

 

So the rear shock is revalveable????

 

yup.
stig at ppsracing can do it. i was actually going to go that route before i got blessed with a penske rear!
he did say that there isn't really much he can do but he can definitely revalve it as much as possible.
