Här är en bra beskrivning hur man "sätter upp" en FCR39...

Bästa sättet är att köra hojen i bänk för att få ett afr-värde att utgå ifrån.
PS. Glömde säga att du bör koppla bort acc-pumpen vid bänkkörning. DS.

Did a couple of dynoruns last year and I was rich all the way so I did a few changes in the settings and got on the dyno again a few weeks ago. Checked the AFR and I´m still a little rich in the bottom, WOT is 13,5.
I did some adjustments to the carbs so now i´m running this setup...
904 cc with JE racing pistons and FCR 39, 60 mm stacks with foam-socks, 2 early 790 IN cams, Procom with my own i-curve, altered timing, worked/fload head, valvejob, Zard 2 in 1 with my own db-killer.
FKR needle in 5th grove from top.
M-jet 140
M-airjet is a drilled out to 3mm.
Slow jet 52
Air screw 1 1/3 turn out.
Fuel screw 1 turn out.
I will run this setup all season and before winter I will do another dyno and hopefully I don´t have to do any changes.
904cc, JE racing pistons, worked/flowed head, 2x790 IN cams, FCR39, , 88 rwhp, Beringer brakes, Wilber shocks, Andreani/Öhlins fork.
