Paul:
Oh no, nowhere near as heavy as stock. It sucks in the tight rocky singletrack of Arizona but, it's a must for a duner :D

 i never heard of PVL , i had heard of guys with very light flywheels..

i add weight to the flywheels now to get them to at least  original OEM..

so its poosible to make a lighter one, in the future ,
that still has the lighting output..

how light are the PVL's compared to stock
(is there % ratio, or a general figure?)

AJ, I'd guess 80% lighter?? Maybe more? Paul correct me if I'm wrong but it is nothing as heavy as stock.

PS: The PVL is analog, that is why I was hoping a digital one would be released.. When I buy another KX500 (AF?) I will put on another PVL system if it doesn't come with it. I can't imagine having a KX without it.

I assume that because the PVL ignition rotor has its weight closer to the centre as opposed to the outside like a normal flywheel it will seem even lighter.

As rotating objects that have their weight around the periphery have more anglar momentum at the same RPM than the same weight object with its weight closer to the centre an internal flywheel of the same weight as a normal external one should be more revvy.

Bit like a gymnast spinning very quickly then throwing their arms out and slowing down.

If you get my drift :-)

gowen:
Very true, but physically holding the stock rotor vs. that flywheel was incredible (weight difference).

thats how they wil be sourced most likely..

I've been working with Kaw for awhile on this actuially, and lurking around here a year or so..;)

Does Kaw have any warehouse stock of complete engines?? Will they manufacture complete engines for you?? Are you going to buy complete kx450f's and just remove the engines or is Kaw providing the roller chassis?? Buying used engines and doing complete rebuilds seems to be alot of time and effort. Thanks for your time on answering our questions.

AJ:
the most likely scenerio is :

much like the cr  500af /afx  bikes--


 i would be buying complete kx450f bikes,

then building the kx500 engines for them from the new parts bin.

we've been testing this last 2 weeks,and really happy with the handling,susp etc.
it will have a proper pipe made up quickly and from there i shold be able to get it released fairly fast!

its a blast to ride, and i'm really stoked with how its coming along,  i think you guys will really like the final product.
