Any hints? What to watch for? Any modifications required? I can think of one - attaching G2 tank to frame and powering fuel pump. Guess I'll have to use G2 electronics throughout also.

I'm doing this more for cosmetic reasons since I like the look of the G1 frame - I'm thinking that the G2 motor/injection is better than G1 although frame geometry is a step back. This will be a naked racer- bikini fairing and portuguese belly pan.

Thanks

A guy in rockwall has a G1 with a G2 motor for sale. I was going to look at it but he stated "almost a direct bolt in."

When I asked him what he meant by that he replied,
"The flywheel/stator and the valve covers are different between the engines and have to be swapped to make the 03 engine work in the 02 bike. Other than that they are a direct bolt in replacement."

dunno if that helps.

nah... that is not true. a guy i know did this and spent quite a bit of money making it work. his reason for doing it was racing. something about the first gen frame being better/more stable for racing and of course the second gen engine has more power...

 

[BombDigs]

Is it possible to retrofit the throttle bodies, ecu, and other relevant parts to switch a G1 to an FI setup from a G2? Im not sure how serious I am about doing it but if anyone can attest that its a PITA thats good enough for me. My money may be better used on a G2 cam swap.

Ask a tuner what engine is better --> Gen 1 or Gen 2. I think most tuners say that the gen 1 engine is more easy to tune. I have read some where that the second gen crank is weaker butt i don't know where i did read it.

You say that you do it for cosmetic reasons?? the only things you see that are different are the oil cooler and the crankcase covers.

You can use the second gen engine with the first gen carbs.

Thanks for the response. I'm going to use G2 motor, Fi and electronics, forks and wheels on the G1 frame.

My understanding is that the G2 motor are a little weaker (particularly the 03 crank), but make more power and can be tuned up easier due to the Fi system. The G2 frame is definately superior but not as nice looking which is why I'm doing this. I currently race a pretty modified 05 SV (suspension, slipper clutch, PClll, brembo master, EBC rotors/pads) except for the engine.

Just use the first gen wheels, they are almost the same.

When you want to put FI on a first gen you also need to mount a external fuel pump. And the second gen tank does not fit.
Ask Zoran from TWF racing http://www.twfracing.com/forums/index.php what engine is more easy to tune. He has the experiance in tuning sv650 engines.

well the motor is in. The secondary throttle body butterflies motor enterfeers with the frame. Wondering how important those sec. butterflies are....

Are those the top blades on the throttle bodies? My 03 had them removed when I bought it and the bike ran great FWIW.

 

[jeopardy98]

Yes, you will just need to use a little throttle when you first start it up cold since you are essentially removing the FI's "choke".

The secondary throttle body butterflies or the servo motor??
When you remove the servo you will get a a malfunction. And the FI light will burn.

 

[Steve sv23]

Yes the servo motor. Is there a way of fooling the system such that it thinks that the motor is still attached? As soon as the ECU throws a code, it goes into limp mode which reduced power to 80%. Another solution would be to mount the motor somewhere else such that it still operates....

 

[Spierings]

Problem is it's got a throttle sensor on the other throttle body. You need to keep the servo and the sensor on the servo. You need to mount the sensor somehow on the servo to fool the ecu.

I'm in the same proces with removing the complete secondary valves on my bored out trottle bodies.
