Hi everyone I have been searching for the correct amount of oil to put in the forks for a rebuild and have gotten like four different ainswers plz if anyone knows the correct amount and thickness I would appreciate some help thanks in advance riding season is close so I really need to get them done

 

The bike I am working on is a 1993 cbr600 f2 forgot to include that oops lol

 

I have a '93 F2 and I used 10W oil in my Forks. I left a 135mm air gap at the top before putting the spring and spacer back in, with the fork fully compressed.

Optimus Prime is dead-correct - '93 and '94 models need 135mm from the top of the stanchion, to the oil, without the springs and spacers, and the tube fully compressed into the slider.

Put roughly 15oz in the fork, and pump the fork tube 5 to 7 times, then slowly add until you reach that level.

 

Get a turkey baster and a piece of tubing.
Mark the 135mm from the end of the tubing.
Slightly over-fill, then use the baster to pull off the excess,
while holding the tubing to your mark at the top of the fork.

thanks for all the help cant wait to get it all back together

 

what weight oil should i get and does brand make a diffrance?

 

If you're not a big guy, and typical riding/cruising is all you do, then 5W, like what the F2 is originally set up with, should be fine - If you are a big guy, and/or will be running the bike at the track, you might want to consider going up to 7.5W or 10W. Truthfully, a lot of this decision is just based on personal preference, and riding experience/skill level... there are definitely guys out there, who wouldn't be able to tell the difference between 5W and 10W anyway, just because they don't ride that hard, and/or don't have that much experience.

There are plenty of good products out there, but personally, I use either Lucas Oil high performance synthetic fork oil, or Moterex racing fork oil, both in 10W.
