chrisg sells the washers, pm him on here
get the bearing from jason at honda east, or ebay
all that stuff shouldnt cost you more than 33 to35 bucks
i have heard a few guys complaning about the stores washers and slow shipping. they have them on ebay to.
you can get the piston kit cheaper on ebay, gotta look for it.
bearing 13.99
http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=99+rm+250+wrist+pin+bearing&_sop=15i think cunninham821 makes the washers also, maybe try to pm him, or ask iceracer. he might beable to give you best deal on all of that stuff, even the piston kit.
but if your dealer can get you bearing under 15, bucks then thats a good deal. you will just need to decide who do you want to pay for the billet washers.
sometimes if you ask seller to pay over phone they will give you a better price than whats on ebay, you get around there fees. you have to ask them tho.
