Best Kawasaki " dealer" prices in the USA

[81cr450]

I need powervalves, the whole setup, for a AF I'm building. Its looking like I need to buy new as used prices are to the point of buying a complete cylinder to get them for a reasonable price. What I want to know is what dealer in all the US has the best price break. I've found cheap bike parts that get the price down to $330 but... Also how many of you are seeing powervalve problems & why. Basically what breaks. Thanks for your time & input, sounds like a stickyable subject though if we all shop from the best price dealer it could help them keep the prices low

you can buy used complete cylinder but most of the powervalves will have some wear on them. The last 15 cylinder i bought complete only 2 of the cylinder had good usable powervalves. Start buying used complete cylinders intill you find a good complete set.

if a dealer is a parts website then go to cheapcycleparts.com  they have real cheap prices . for example

cheapcycleparts.com = 89kx250 kickstarter =$133 shipped to canada , $103 for the kicker

my local kawi dealer = same thing = $180 plus tax!!!!!!!!!!
