TGR , try another dealer.
Although it IS possible that those parts are obsolete it IS also possible that that particular dealer either:
A- Is too lazy to hunt for the old microfischs on your bike.
B- Would rather see you get frustrated trying to fix up that good old machine, and buy a new one from him. (what to do for parts on that NEW one in a couple of years, eh???)
C- He could just be "old bike predjudiced" and want to see another good old faithfull Honda XL go down to the scrap yard. (where are these new hightech wonderbikes gonna be in 10, much less 25 years?? huh?)
If they are truly gone, there are always plenty of salvage yards out there to search thru not to mention lots of bike shops that specialize in parts for our beloved older machines.
If it ever gets back online try xlintperformance.com for a start.
Good luck, and keep 'em rolling!! :cool:
