I thought the Rc30 heads used the shim under bucket style valve train like the Rc36? Don't the Rc24's use the rocker arms with locknut adjusters?

This. ^^^^^^^^^ You would have to saw off the swingarm pivot casting from the 800 motor then figure out the engine mounts, and no guarantee the sprockets would line up, even after figuring out the first two items. Better to use some other motorcycle throttle bodies and run them off a Microsquirt, using the 750 engine, but you'd be basically on your own, as I'm not aware of anyone else doing this on a Vfr. Actually, Durbahn racing in Germany has adapted throttle bodies for use on the RC30 engine, which is essentially the same as the RC36 engine at least externally. IF you have decent fabrication skills, and know how to tig weld, It would probably cheaper to modify an 800 to fit the 750 when all is said and done. I'm sure the throttle bodies themselves are well over $1000 US, and that doesn't take into account the ecu, wiring harness and dyno time to tune the beast.

I think that was flyguyeddy, not sure if he got it worked out though Well, its not going to "bolt right in", but anything can be done with enough time and money. Hell, there's a guy who stuck a 4th gen engine into VFR400, so anything's possible!

Ehhhh.......not sure. What type of business would most likely be using them? Your best bet is a good automotive diagnostic shop. We have a Bosch MTS 5200 lab scope at the shop where I work, complete with a low current clamp, and a bunch of other interesting test adapters(even a pressure transducer for testing running engine compression!). There has to be someone in your area that does a lot of automotive driveability and electrical diagnostics.

Sync'r up and put her on the dyno!

It would be interesting to see what the spec is on the 6th gen coils. I have a feeling they have built in ignitors judging by the extra wire.

The dwell time is controlled by the ECU, it basically grounds the coil for a certain amount of time. The lower resistance coils, like the CBR coils, require less dwell than the higher resistance coil. I believe this is where the problems arise. If you have too much dwell with a low resistance coil, you could eventually damage it or the CDI/TCI/ECU. If you ran a high resistance coil with a short dwell, then you won't charge the coil long enough to get a powerful spark.

If rangerscott is willing to buy one of the $60 pocket oscilloscopes like what I have, he could well do that. "Lab Scope" is an automotive term which generally means $$$$$. They're just oscilloscopes. Thats true, you should be able to look at an ignition pattern with any oscilloscope, I'm just used to using the "lab scope" term since we have one here at work that I use on occasion. In reality, we really have no way of knowing if the ignition box can handle the extra current, we just have to assume it will eventually fail prematurely since it was designed for a lower current.

The best way to figure out if this is going to damage the CDI/ECU is to hook a lab scope up to a coil with the bike running and compare the ignition patterns between the two different coils setups. I actually ran a set of these coils on my Audi S4 a few years ago without even comparing the resistance values with the original coils, it ran great, but I sold the car shortly after the conversion so who knows how long it lasted!

Just took a look at a wiring diagram for an 07 600RR. All four coils on that bike are powered by 12V directly to the ignition switch, with individual drivers for the ground side of each coil, basically the same way a 5th gen or even a 4th gen is wired up. The only difference in the ignition systems besides the coils themselves, would be the CDI or ECU. Maybe a 1.6 ohm resistor on the ground(ecu trigger) side of the coil would work? I wish my bike was a little closer to running condition so I could try it out.

I've used these coils in many different applications with stand alone engine management, its always 12v on one side, ground trigger on the other. The only time I've seen a ballast resistor used on an ignition system is with older vehicles with a points system. I have yet to see a modern coil pack use anything less than a 12v feed. You want to have the highest possible primary voltage so it can be stepped up to a high secondary voltage, 6 volts on the primary side just ain't gonna cut it with a modern high compression, high rpm motorcycle engine.

Why not run two separate 12v feeds and then have the ground side of the paired coils grounded by a single driver? The ecu will think its still firing a single 3.2 ohm coil, it shouldn't care if the other driver is controlling nothing.

That being said, I think I remember reading somewhere that the 5th gen had individual cylinder timing, maybe it was fuel trim...can't remember.

I'm thinking you may have to run the coils in series like those guys did with the ZXR, you would then only need to use two coil drivers, and run it as a wasted spark system. Just make sure you get the correct coils paired up! I don't think the ECU/CDI in these bikes are smart enough to know you're not using two of the coil drivers, could be wrong though.

I plan on using the CBR600RR stick coils on my 4th gen project, the stock 4th gen coils measure 3.2 ohms on the primary side, 07 CBR600RR coils are 1.6 ohms on the primary. Secondary side of both coils is a lot closer, can't remember exactly what the resistance numbers are off the top of my head.

Now that I have a CBR600RR to play with, I'll be starting work on my 2000 frankenviffer. Plans so far include RC51SP2 front end conversion(pending, may go with a more modern front end if funds allow it) RC51 swingarm conversion Replace the frame with a sixth gen frame I picked up cheap(mine is cracked where the subframe bolts on, plus its salvaged) Generally lightening of the bike, she's not going to be much of a sport tourer when I get done with her! Already have all the RC51 stuff from a roller I purchased a while back, just need to make room in the garage so I can start tinkering, guess thats the first project!

Thanks Luigi! Now I need to go measure my CBR600RR swingarm again to see how far off it is!

awesome, thanks!
