I've also recently replaced the jet in my 1999 mille, big difference, especially from cold, however also replaced the fluid with the brembo racing stuff (liquid gold is cheaper I believe!!) and bled it really well, new clutch kit (stock) and oil. But, I replaced the jet after I road tested the new clutch just to see the what the fuss is all about....Its a different bike !!! hope you have the same !

I changed it also, my bike stayed the same 
But finding neutral when cold is normal now and the bike doesnt pull foward anymore when cold, so its good. Also changed the oil from full synth to semi, so dont know whats responsible for the change.
Shifting feels the same, not realy a fan of aprilia gearbox, its good, but its not great, like ducatis. And i managed to get it out of gear once, probably got a bit rusty offseason (me, not the bike), I just dont know why they put neutral betwen 4th and 5th gear

been looking at doing this as my bikes a nightmare to get into netral from cold,
but, i read that the jet was reduced from a 60 to a 40 as time went on, with my bike being a 2004 tuono, is it likely to have the smaller 40 jet fitted already?

Ive just changed mine now. Not had chance to try it as i am STILL waiting for my new Immobiliser ECU (only been a month so far) so cant start to check... Been a fault on my bike for months now so im hoping its worth waiting for....
However, i found it a good ide to use a strand off a wire brush to fish the valve out of the engine casing. Held with a thin pair of long nose pliers it was nice n easy.......

Hey Guys
Let me throw a spanner in the theory.
I run a heavy duty barnett clutch in my 2000 RSV, instantly after installing I could no longer shift into neutral at stop. I MUST now shift into neutral whilst rolling to s stop.
I installed the JET40, and can positively state that this had NO effect on helping it get into neutral whilst still. Maybe its a good mod only if using the OEM clutch kit??

richmond dont worry about the oil seepage its normal ,you will also get a bit more when you remove the .60 jet its tiny so use a small flat screwdriver,with a bit of fiddling you'll get the other one in do it up hand tight replace the bolt and enjoy finding neutral ...if its still hard then bleed your clutch ,another good mod would be a 15tooth sprocket on the front [oh my god its a friggin missile lol] this will make it smoother in town and OH MY GOD THIS PULLS LIKE A TRAIN acceleration enjoy
Modification....Jet 40 and Oberon clutch slave cylinder....wow...amazed...
After reading this thread i had to do the mod...I have a 2002 rsvr and the heavy clutch and neutral problem was a pain but now its fantastic, the clutch feels 50% lighter and neutral is absolutely easy to find.

Iv'e got a 2000 model and also fitted a barnet clutch, then couldent find neutral, just fitted a 40 oil jet and its cured! I can get neutral from 1st or 2nd easily. New slave cylinder next.
Is it easy to fit or would i be better of letting a dealer fit it as i am not hands on with motorbikes

Same result for me...when i bought the bike the first thing I did was buy one of the 40 jets and installed it....AND!!!
