I want to put a set of inverted forks on a 02 F4I... Which ones work and what trees do i use and do i use the stock steering stem?

 

NO NO NO, STICK WITH STOCK F4I, ALL U NEED TO DO IS CHANGE THE FORK OIL TO 15W AND ADJUST YOUR SETTINGS, OTHER FORKS BLOW FORKS SEALS FAST

I CHANGED MINE FOR LOOKS AND CASUE I GOT A GOOD DEAL,
I LIKE HOW F4I FORK SEALS HARDLY EVER GO BAD

 

i got 600rr on mine and used the same triple and stem from the rr

 

what year RR forks and triple???

 

i have 07 others work too tho

 

There are a few different fork set ups to go with on the f4i....1000rr, 600rr, rc51, 929/954, even seen some R1 forks on em.....search around the "help and how too" section

 

+1 lots of post about that in the help and how to section

 

and i have a 954 front end on mine and i use the 954 triples

 

+1
they are a little shorter though


only problem i see with the f4i forks is they are conventional and not inverted, because of this they are easier to bend. if you don't crash a lot it shouldn't be a problem though.

 

why is 15w better?, thicker viscosity? how do i change my fork oil?

 

i think your just fine , that would benefit the heavier riders to change oil,,stiffer springs etc...dont do it urself the spring has tesnion under it and will spring out with force and u would need a special tool to get the spring back in....ask gil he would know if u needed it

 

some local shop changed my 1000rr seals put in 30w harley davidson oil casue a local stunt rider told them thicker is better, now my forks are wayyyyyyyy to stiff , I cannot roll stoppies farther than 50 ft now ( no balance point) and blew a new fork seal in 1 day...

iam going back to 10w

 

ture true, have a shop do it for sure..

 

You can definatly change your own fork oil, just get the manual and pop em open. Never had any trouble getting the spring back in and definatly never used any special tool?? also if you want to change the seals and dont want to buy a driver, just cut a piece of pvc pipe and use that

 

this is true of inverted, not conventional. f4i forks you pretty much just take off the cap and dump the oil out, then add the required amount. it is very important you put the proper amount of oil in, on an f4i its 15.6 US oz +or- .08 oz

 

yes ur right i did mine when i owned the older gixxers they were all inverted... i never messed with the f4i s ,i thought they would be the same.....ay u learn something new everyday

This is what I use to change fork seals/oil in inverted forks.
Conventional forks (like F4i, 01-03 gsxr) do not need a tool.

 

you cant put inverted forks on an 02, you can do it on any year except the 02's.... dont know why, they just dont fit!

 

what don't they fit

 

thats funny cause my 02 is sitting in the garage with 07 600rr forks on it.. and they fit just fine
