What do you have to do to use F3 forks, exactly?

F3 forks must have with them in order to work:

F3 fender     \
F3 wheel       >  ----   These 3 must go together,these are not interchageable with F2
F3 calipers   /              front end parts


Exceptions are listed below*.

I recommend using an F3 lower triple clamp when doing this changeover

*Now,you can use F3 internals in F2 forks,with some small modifications to the F2 dampening rod uppers.All cartridge uppers will swap.

*The F3 fork leg uppers and internals will fit F2 fork leg lowers.

Make sure you use new seals when re-doing suspension.Use OEM seals,they are the best.

I'm going to start building an F2 from the ground up.  Bare frame that is.

I'd rather use all F3 parts if possible, but does anybody know what F2 parts I'd HAVE to use?

so 95-96 lower and tail fairings will fit on a 94 F2 with out having to change any other parts, but if you wanted to use the 97-98 on a 94 f2, you'd need a new seat and tail light?

I was looking over that list and learned a lot. My input: I am quite certain that the wiring harnesses are different. The CDI box has different number of pins and F2 has no elec fuel pump.

thanks guys. I was kind of skeptical about ordering the lowers since the inspection windows looked bigger. I guess i won't have to worry about it anymore.

One thing will always be a constant.

Voltage regulator!!

FWIW, I think the calipers and brakes on the front are the same up until 96 which would include the F2 and some years of the F3. I know every time I have priced them out, the years always show to 96.

Smae thing goes with mufflers. Every place I have priced them out over the net shows muffler being same at least through 96 and some to 98.

Nope,the calipers are different.

F2 years 91-94
F3 years 95-98

See my post above.
