Need some help with a little project I picked up. 86 kx80, need a head pipe for it as this one is all rotted out just down from the head. I can't seem to find 86 pipes, dg has one but it's pretty pricey. Are there other years that will fit? Thanks in advance!!!
 
Best, thanks for your links. I've seen those already, but can't seem to pay that much for the procircuit, the other pipe doesn't list a year, is there a big difference in years with these bikes? Don't want to get one and it not be a direct fit.

the whole and only point of the rockymountain was the oem part number.
not the aftermarket parts.
the firsts ever bike i had was a 87 kx80 bigwheelo_O
i was 14 lol sooo 20 years ago
 
Ok, so the p/n is 18002/a, so when I search for this it come up with kx500 parts but It's a longer pn like 18002-xXxX. Am I just that dumb and can't figure this out?
