Maybe not a 12V (never tried to be honest), but it certainly does work with the bigger engines. Running an agressively timed cam (Duration, seperation) will definitely make them lope like a pig. Since I put a hot cam in the 903 it spits, sputters, bucks, lopes, you name it. Thats only til it warms up and starts to rev a little more. But they sure as hell will. This cam still has the stock injector lobes on it too, so that has nothing to do with it, of course the timing on them is slightly different, and it flows a lot more fuel, but it did before the cam was reground and it didn't idle like it does now.

Okay, so I'll make this plain and simple...fuel makes it lope...bigger injector lines, bigger injectors, more fuel makes lope.

Heheheheh...

Mine only lopes when its fairly cold or if I am letting out on the clutch with very slight throttle. The DDP3 injectors do that, in conjunction with the 3GSK I believe..

I know the fuel plate wont make it lope like that, but it will add the fuel to it to make it smoke kind of like that rig in the video, and push out some additional ponies.

The thing is, you want large amounts of fuel dumped in at idle, a'la big injectors and or big crossover and injector lines.

crossover tubes are in the head I'm pretty sure. I'll see if I can find pictures.

no one is listening to you cause they're watching your avatar.
Mine does that whenever my shutoff lever isn't fully closed, since its cable operated.
