So a couple years ago I built this thing and in the end i swapped a CBR954RR engine into it. And while it’s stupid fast it is also loud, twitchy, stupid fast, difficult to control and drive, and every time i drive it something breaks...motly i’ve caught up with this but the fuel system i have is not capable of keeping up with the engine.

So I’m putting a milder engine in and am really leaning toward the Predator 670. I want to keep the Geo Metro gearbox I’m running, though. Has anyone seen a setup like that? I’m not looking at being able to row through the gears, i expect to tie in with a clutch or cvt and what I’m hoping is that i’ll be able t9 use may e 3rd or 4th as a running gear but be able to drop into lower gears for climbing or pulling.

Just looking for input, advice, or suggestions about this project...what kind of hassles I might be in for.

Thanks!

For ideas adapting to an automotive transmission, check out Mike Festiva's youtube. If you're unfamiliar with him, he builds some impressive vehicles, and he adapted a predator engine to a subaru transmission in his 4x4 articulating dump truck project.

Could be useful for some ideas.

I watched through his videos and he went about it about the same way, except he used a centrifugal clutch instead of a CVT. I'm actually really surprised that clutch is holding up to the abuse he's throwing at it.

I agree. I've never been able to keep a centrifugal clutch in good working condition for very long.
