How often does the fork oil need to be changed? when i brake the front end takes a dive. one of my buddies said the oil might be old. I think my suspension might be too squishy. I bought the bike from a guy that was about 185ish. I'm 220lbs. Is there a way to stiffen up the suspension?

 

there is, but I'm not positive what the method is on the F2's. I would make it a point to change the fork oil every 10k miles or every other season though. its one of, if not the most neglected things on a bike because many people dont realize that all moving parts require oil to work well for prolonged periods of time.

 

Yes,change the fork oil. 15 or 20wt synthetic will do you well.

You can put in new springs from Racetech or Ohlins.The spring rate on a stock set of forks is.73 .You may want to go to .90 or .95 ,given your weight.

Holla back

 

i guess i should have asked how you change the fork oil cuz my clymer doesnt say how.

 

I"ll help as much as I can, probably the easiest way, is by pulling the drain plug on the bottom of the fork leg. Look in your clymers manual, Chapter 10, page 327, on the breakdown, the bolt to remove, is part #20 titled Drain bolt. remove the top cap as well(carefully, the spring under it puts some pressure on that cap)

The purpose of removing the top cap is twofold, first, it relieves the negative pressure in the fork allowing the oil to drain out the bottom, and second, when you put the drain bolt back in this is how you refill the fork with oil.

Note you DO NOT measure the oil in ml, instead measure it by how far from the top of the fork it is with the fork fully compressed.
I got this info below from the Clymer manual, in the first page of quick refererence data.
The fork oil height for your bike is:
91-93 model is 118mm or 4.65" from the top of the fork leg,
94 models its 135mm or 5.31" from the top of the fork leg.

I hope this is helpful

 

the fork oil level is measured with forks fully compressed and with no spring in it, those numbers don't sound right on the level, should be muchlower than that, I'll double check later but I think its 18 mm not 118

 

I got my mm and cm mixed up my my head and it didn't sound right, stupid metric his fork levels are correct

 

aye! thats the small fault of the metric system for you. 18cm or 118mm would be correct either way, since both are the same thing. Metric is actually simpler for me than SAE sometimes. now if only they made a damn metric tape measure for me, I'd be good.
