I'm tearing one down right now. I dont have tons of experience with aftermarket chassis' though. The JRD seems nice, the handling is insane. I've had a small amount of cracking issues, but those are mainly because of the previous owners actions, the the quads was beat to hell already. A few welds on the frame are only welded on only one side, when they should be welded on both. If I was in the market, I would definatley buy another.

One of the nice things about JRD frames is that you can put like 3 or 4 diff. engines in just one frame all you need is diff. motor mounts and they say that you can take the valve cover off the top of the engine and not have to take the engine out of the frame which is nice. I have a lonestar frame with a CRF and if i want to adjust the valves i have to tilt the engine forward which kinda sucks but o well as far as the frame cracking is gonnin happen espelly if you race motorcross or ride hard.

a-arms, motor mounts, and subframe mounts are what comes to mind.
That's a sick quad, and the guy who built it (jrspawn, i think) seems to be a smart guy who knows alot about hybrids.
Everyone talks about the 4 speed YZF motor being awesome, but I'll stick with my CRF.
First, ride the quad before swapping motors, I doubt you'll want to after getting some seat time.

yeah, i picked it up this morning. justin definately knows about hybrids. it looks great in real life.

also if i were to switch to a twist throttle, would i need to use just the stock yz426 throttle?

Does anyone know what is all used in the crf450 to 400ex conversion from the crf 450 just the motor? is it better for me to buy a whole crf 450 because alot of stuff is used from it? or just the motor to put into my 400ex can some one tell me what all ill have to buy to do this conversion and a ruff price on what it will cost to do this?

[stocktires]

motor, carb, electronics, clutch/hot start, and maybe header from the crf.
Lots of fab and motor mounts for the conversion. Intake and exhaust really sux to fab up.

[kris_400ex]

do i have to have custom cables made for the gas and clutch or does it use the 400ex or the crf450's? and what radiator does it use the crf 450's? or is it a custom made one that someone sells?
