rm 80

got it.. used a spring puller... on top of the piston it says 05 whats this mean? 50 overbore? need to know so i know what rings to order..
 
oh and cause i only had 600 bucks and couldnt go wrong! haha cant wait to get this beast runing.. still cant believe it has powervalves
 
idk i dont think my friends kx has one.. and not worried about it ill be beating 85's :) hehe
 
hmm intresting.. all the powervalve does it give it more backpressure on bottom end to make it better in trails... so no help on topend anyways.. cant wait to drive this biotch!
 
that was a good price, i see them cheap all the time when they need work..

all the 80s have pv's other then the real old 80s.. and i beleav the 60 and 65 has them too.. i kno my buddys ktm65 had 1.. and i dont think you will be crusing arund on your 80 in the low end i am sure you will be screaming so the power valve will help on top end..
 
hows the powervalve gonna help on topend it closes on bottom for more backpressure and open on topend for less no differance on topend.. haha
