Yeah, their on-line catalog leaves a bit to be desired, 'eh? They know it's short on info...I've griped at 'em about it, they said they're working on it.
.....that was a couple months ago. :(
If it is a reed cage you're looking at, make sure it's a deltaforceII, not a I.
From them:
A very obvious difference that should
help people out is that the VForce Delta (the original one) has a black
cage and manifold, whereas the new VForce Delta 2 has a gray cage and manifold. Also, the reed tips are recessed on the new VForce Delta 2 and one the Delta they are not. One last feature that stands out is
that the VForce Delta has rubber coated tips on the cages and the VForce Delta 2 does not.
It doesn't help that BOTH of them are called 'VForce' or 'VForce Delta'. Their appearance is significantly different...their performance difference is HUGE! I've ridden a kdx with BOTH of them (not at the same time;) ) The DFII has adjustable tension reeds, the DFI does not.
The MotoTassinari website lists the V2M031 as the assy for the kdx, $148.
The petal replacement list does
not show the replacement reeds for that cage...call them for that.
You'll love the DFII. Mine replaced a radvalve (that I'd just put new reeds on, so tired reeds wasn't part of the equation). Ran it 'high tension' for a few rides, switched to 'low'. A HUGE improvement for trail/woods riding!
Anecdotally speaking: My riding buddy (then also with an '00 200 equipped almost identical to mine) would consistently outpull me with the MTII. He 'traded down' to orange ('01 200 exc). Then he REALLY walked away from me. I put in a DFII, and even set to 'low tension' I keep up with him much better. Yes, he still outpulls me, but it's an inching process...not running away like a wabbit!
It's second only to a pipe in its performance enhancement.
sez me, imo, imho, etc etc......blahblah....
