Proper tuning for a 1986 Yamaha FJ1200...

[europe50]

Hey guys,
My 1986 Yamaha FJ1200 completely stock except for a Supertrapp 4-1 exhaust and a K&N air filter in the stock air box (Slightly opened up).
I do not race the bike, I just sport/tour with it, but....
Do any of you know what the proper jetting (And needle height) should be for my FJ with the parts added above?

Here is the stock jest for my Fj:
Main jet: 112.5
Main air jet: 45
Jet needle: 5FZ72
Jet needle clip position: fixed
Needle jet: Y-2
Pilot jet: 37.5
Starter jet: 30

Thanks!

I ran mine on stock settings with the pipe open, no plates in and it was fine with the mixture screws out 3.5 turns. Take the plugs out after a run on the free way and see if there brownish. I lost a lot of gas mileage and bottom end with the pipe, so I went back to stock.

Honestly, it's such that you have to find it out for yourself.
