1980 Yamaha XS1000 Midnight Special Carb Cleaning?

I have a 1980 Yamaha XS 1100LG Midnight Special that I think needs the carbs cleaned and re-calibrated? Bike has 18,000 miles on it and ran well last year. But……I left gas in it without stabilizer (DOH) and think that is the problem. Bigger problem is ……….I’ve never done the work myself. Dealer can “burn through $800.00 pretty quick” barring any other problems.

Two questions:
1) Know any mechanics in New Jersey that would fix it?
2) Where can I get info on dismantling/cleaning myself?



If the carbs sat with fuel in them for a season then it is likely they need to be cleaned up. It doesn’t take much to clog up the jets.

To answer your questions:

1.) I never recommend taking a bike to a dealer. In my opinion, part of being a true motorcyclist is having the knowledge and skill to repair and maintain your own motorcycle. Motorcycles are about independence, and you lose that autonomy when you become reliant on a dealer.

2.) You can download the Yamaha XS1100 Service Repair Manual from my site. And you can follow my article on How to Clean a Motorcycle Carburetor

If you have any questions along the way post them here and we can help out!
