I trawled the internet for KX 500 photos a while ago and any that looked significantly different from standard I copied the picture of onto my computer.
Can't remember where this pic came from and I hope you can see it cos its of a sand drag KX500 with a bleedin huge expansion chamber on it, its as ugly as fook but no doubt does the job and if I squint just right at the full size version (that for some strange reason I am unable to post on this thread) I can see
CPI racing stamped on it.
I don't have the foggiest notion who owns the bike so its not even worth asking me, sorry.
I looked on CPI Racings website and it says they make custom pipes for polaris and Ski Doo and so on, no mention of motorbikes but as they have alread made one for a KX500 it might be worth a phonecall?
