This year bought a 1979 XS 750, and although I know from reading this forum it is not the best bike Yamaha made, I would like to persevere with her. She has been running quite well with surprisingly few electrical problems. I live close to Seattle (Vashon Island), and would like any recommendations for a shop who can set up the carbs- Twin Line won't work on any past 1978, and the other choice is Southend Motorcycle Service- has anyone used them ? Apart from Ebay, are there any shops in Seattle that sell parts for my bike ? Thanks- Spencer
