I saw here somewhere the up sized jets for a 3ln1, does anyone know what sizes they are. I have the standard sizes but I'd like to try some bigger jets. I checked with Factory Pro & they don't do them. I've got a set in a ZXR750 & what a difference it made. The fzr has a bad flat spot around 3k & I think a bit more fuel will fix it, if I can get the pilot jets out, 2 are stuck & the groove has gone.
