Hot Rods suck, I'm not afraid to say it....I know too many guys that get maybe 6 races out of one if they're lucky, in 80's and 250's...garbage.
My Kawie dealer wont even get them for customers if they ask anymore, because they last such a short time. Customers are trying to get their money back by saying they got defective parts...and trying to blame the dealers mechanics for installing them incorrectly and getting money back that way.
I haven't heard much positive on the Wiseco's either, but no where near as bad as Hot Rods.

These are retail prices.
If you score a discount on eBay or have a buddy who set's you up, so much the better.
But for the sake of the average guy comparison we will use Retail.

92-01 kx250

Hot Rods 289.95 includes main bearings and seals (Retail)

Wossner rod kit 109.95 (Retail)
Pro X bearing and seal kit 49.95 (Comes with factory Koyo bearings and OEM seals)
18.00 for USPS Priority shipping and about 400 in insurance. (This gets the crank to Todd)
80.00 for the rebuild and approx 20.00 for return shipping in the USA.
Total $277.90

Thank you for putting that together.  I think most people go with Hot Rods or Wiseco because they are convenient, and they are unaware of any other options.  It's nice to know that using quality parts doesn't necessarily cost more.

Is there an address for Pinsonnault under there section on this site, or do they have a website?

sandblaster:
Yep...

Thanks guys did I mention the entire KIPS were completely seized with spooge??

The flapper valve still sorta moved in and out but the pinion gears off the main governer rod had to be pulled with vice grips..





After going over with a pressure washer, I can actually reference the different parts mentioned in the manual..



Good thing I am already familiar Kawasaki powervalve system as I already ride a '90 KDX200 but the flapper valve mechanism is new for me

KIPS subvalves and flappers, rods and other bits all cleaned up...Gonna send the jug off to a parts cleaner because I won't be able to get in the holes to clean them properly..



umberto:
Sounds like you are on top of rebuilding the KIPS, but this might be helpful.  I found this video on YouTube that details how to put the KIPS back together on a 2002 KX 250.  I think it would be a pretty good reference for your rebuild.
