[apex580]

I hope not to annoy anyone with this question! I have a 1997 580 EXT EFI 121" track, and am looking to increase it to a 136". I have contacted some dealers and they say it is not available anymore! I find this extreamly upseting, due to the fact that I can still get longtrack kits for older Yamahas. If anyone can help locate a kit for my 580 or ideas it would greatly be appreciated. My 1997 580 EXT only has 500 origional miles on it and I sure don't want to spend &#367,000 for a 136" track! Thanks to all
