Roberto, I'm about 2 hours south of you, but do old bikes a lot. If you get desperate, give me a call at 361-935-3746 or e-m me at
jackgiesecke@cableone.net. Major shops don't like messing with older bikes and that keeps guys like me working.
I seem to have a rep now for doing older wings, GL1200s and such. Shops won't touch 'em. They're total PITAs to do, but not nearly the pain some of the newer cruiser stuff is. At least the motor, heavy as it is, drops DOWN with a transmission jack. I nearly pulled my back out on a Vulcan 1500 once.
I really don't quite understand why shops don't mess with 'em unless it's the age of their mechanics or something.
But, there's one in Victoria that won't touch anything over 10 years old, go figure. I know that I've gotten requests to do bikes that are totally trashed, would take more money to fix IF you can find the parts than the bike could ever be worth. Better off buying a new one. I just tell 'em, hey, save your money and part the thing out and look for something newer. Bikes like that can take a lot of work just to get to fire and if it's got bad wiring problems, well, forget it, I won't mess with it. It takes too long most times to sort out electrical bugs unless you just strip it all out and install a new harness and the guys around here ain't looking to spend that much, usually. But, if all the bike needs is a good tune up or carb cleaning, heck, why not accept the work? Maybe it's a parts thing with 'em, but I'm thinking they just do a blanket "no bikes over 10 years" to avoid the junk repair that they know is a losing deal. Most older bikes are full of dirt daubers, cob webs, and have been sitting so long all the seals are dry rotted, just not going to convince your average non-mechanical guy of what it could cost to fix it right and if you don't fix it right, you get a bad name with guys that don't know any better, so I think that's why they lay off the old stuff. Too, finding parts for a 20 year old bike can be time consuming if not impossible. I've done old bikes, found parts on e-bay or findmypart.com or where ever I can for 'em, but it takes so long just to get the parts in and doing the searchs is time consuming. You're not going to find a major shop that's going to mess with that. If he can't get the part new from the warehouse, it ain't gonna happen.
Then there are the guys that bring in a 1976 Suzuki GT750 all rusty, dry rotted tires, been sitting in a barn for 20 years, has 1500 miles on the clock, think you can make it run like new for a few hours work. Some people are just morons. If you get the thing to run, it don't run like a new one, they are all up in arms about it. Just don't pay to mess with guys like that. Rather than have a blacket "I don't work on anything over 10 years", though, I just take 'em case by case. I don't do a lot of work, not high volume, and have the time to do it that way.
