1991 KX250 Expansion Pipe
« on: September 20, 2017, 12:31:10 AM »
Hi all, I'm new to the forum so apologise if I'm about to raise a topic that has previously exposure.

I have a 1991 KX250 which has a pretty mashed front expansion pipe.
Does anyone manufacture an aftermarket replacement front pipe. I see FMF offer up a fatty pipe that is compatible with a 92-93 KX250 and also fits a KDX250 91-94, but does not state it fits a 91 KX250. I'm guessing this is because it does not clear the triangular rear shock mounting that is on the 91 KX250.

Has anyone successfully altered the FMF pipe called out above to a fit a KX250 1991, or is it impossible.

I don't know of any new pipes available. You can search Ebay for a used one. You also could send yours out for repair or, if it isn't too bad, you can repair it yourself.
'90 KDX 200 (rebuild - DONE!) - '94 KDX 250 (soon to be a KDX250af)

It appears that DynoPort still makes this pipe. Give them a call or send an email.
