Keihin Flatslide jetting? FCR39's on SV650

[carsick]

Hey folks, anybody here run Keihin FCR39's on a first gen SV650? I have that combination and it came to me without any main jets. I'm looking for a starting point. Stock motor, Hindle pipe, 15/45 gearing and track day use only. Tried the search feature, no luck...

Don't have any insight for you but god bless you. Thy are gonna be a bitch to set up but be sweet as honey when you get them running well.

Might want to give the guys over at FactoryPro a call.

Pretty sure I was running 162 to 165 Keihin Main Jets on my SV Superbike with hot cams and stock bore pistons & compression with Full M4 Exhaust. Had to revert to bone stock bottom-end after Falicon rod broke on +2mm motor. The key to getting good performance with Flat-Slides is to adjust the spray duration of the accelerator pump (typically about a second is better than too long). Also ran K&N Pod filters that just squeezed together enough to fit under gas tank with proper carb adapters.

Thank you for the starting point. I'll aim around there to begin with.

Deal! Meet me after the first few trackdays, I'll be needing the coin by then.
