Default swapping injection for carbs.

As some off you might know, I've put an SV650 engine in a KR1 frame ( http://forums.sv650.org/showthread.p...hlight=janbros ) . I'm still testriding the bike, but I can't seem to resolve my fuel-problem (well, not in the way I would like to - there just isn't anymore space to do what I want/need to do to get it fixed ).

I have an injection so now I want to swap it for carb's . this way I only need a small fuel-pump, and I can ditch the big one I've got now from a Busa (pump outside the tank).

So I want to find out if I can just put on carbs/loom/CDI and adapt all the rest, or am I better off selling the lot and buy everything from a carb-model. I'd prefer the first one, since my engine still has only about 4.000km's. I already looked at part-numbers and the electric sheme's and it appears to me that there ain't much that wasn't altered when going from FI to carbs

you will need a flywheel from a curvey, not sure about the pickup to make it work, plus loom+bits and ignition unit

do you know what is different about the flywheels ? is it just the timing that is different ? FI has 7° , carb's has 5°, so if it's just that, might be some performanceimprovent by leaving it .

i cant remember, i think the FI flywheel has loads of pickup points while the carbed has only got a couple as it does not need to know the exact crank position at all times

dug into the manuals, and had a look at some ebay-pictures, and you're right

does the carb model also have the anti-theft device in the ignition switch ? if so, is it the same or a different one ?

Small resistor in switch which ECU senses continuity to earth through.

Swap everything, rotor, stator, intake boots. (loom, CDI, you know rest...)

make me an offer . I'm from Belgium though, so will have to ship overseas. loom has some adjustments. nothing altered, all connections are original, but I've openend it and retaped it (and lengthenend some wires) so I could parts on different places compared to an original Sv.

what are the problems you are having that mean you want to move from FI to carbed?
im sure there is a work around
