Re: Fork oil ?

If everything else with the forks is stock go with 15wt. brand is not real important as long as it is fork (hydrolic) oil.and 'thicker and the fork action will get way too harsh.

simply adding heavier oil will not stiffen the forks. it will make the damping seem stiffer and give a bit more bottoming resistance, but you will not be getting the most out of your forks.

A set of fork springs is the best/cheapest way to go for improving your handling.

if you are under 185 lbs progressives will be fine (last I checked around $70)
over that and you will prolly want to go with race tech or traxxion. ($109 last I checked)

Re: Fork oil ?

thanks,
if the bike is in good shape your best bet is to go for a set of springs and update the front brakes. The calipers and master cyl from a 99-04 R6 will bolt right up so keep a sharp eye on ebay. just remember that you can't run the R6 calipers with the fzr master cyl.

here are a couple choices on suspension parts for your bike.

I ride a 95 yzf600r so my bike is not that much different than yours.

Re: Fork oil ?

SO you didnt say what was actually WRONG with your forks??!!

Almost any forks can benefit from a good cleaning and fresh oil

Stick with what the OEM recommends. Forget what the book says, collapse and fill the forks to within 6 inches of the top. Extend, put the springs in and go!

You can use some PVC pipe to make spacers if you get too much bottoming.

Thats the cheap route

Re: Fork oil ?

Bill, Thanks for the links and info.

Pete, I have only rode this bike about 25 miles on the street before taking it apart to prep it for fasttrax school and no where to test till I get there. I'm around 215lbs with gear, standing on the pegs and doing the two hop, fork travel is a little under 2 inches, feels a bit soft.
Don't plan on being fast but want to get through the two day race school at the end on April and hope to do a 30min endurance on sat. without being a fish out of water. Without knowing how it will feel to begin with I don't think I should try to do many changes at the track this time around. The old change one thing to screw up three others rule applies with me.
