so far, &%$#@! this motorcycle, and yamaha for making these POS carburetors. Being a mechanic in the army and at home and a carpenter by trade, i believe i have fairly decent deductive reasoning. I learned from a young age (with my sisters easy bake oven, lol its a family story now) that if you take something apart, clean, lubricate and replace all old/worn parts, then put it back together in the same way you took it apart, it should work better than before. With regards to Yamaha and their YDLS Carburetor, they can eat my butt. So very disappointed in the lack of help customer service and knowledge of anyone at ProCaliber Motorsports of Bend, Or. When one goes into the most professional/appropriate business to find information/help about these carburetors, not a single person in the entire &%$#@!ing building has any idea about anything. Then have the audacity to suggest for me to check ThumperTalk! Obviously I'm not apposed or else i wouldn't be here, but when a professional Yamaha mechanic does not have the knowledge, one should not be referred to an online forum where literally anyone and their mother can throw their two cents in about what they think "may" be the problem. Not that its not appreciated, because it very much is, especially to all of us who are in this same situation. But I expect professional knowledgeable service from the only one appropriate place a Yamaha owner should go to for information regarding Yamaha products, the Yamaha dealership. Only to be greeted with incompetence. So if the carburetors the issue even after rebuilding it, just say &%$#@! it and buy a new one. oh wait. you cant. oh wait i found one online! oh. . . its $800. OMG!!! ok there must be a common after market replacement carburetor that is intended to replace these, as i cant be the only one dealing with this. Think again Mr. Frodo. This motorcycle isn't that old. this should be this difficult. So, now that i have done tons of both mechanical and aesthetic restoration work, including rebuilding the carbs, cleaned and replaced the entire fuel, air and ignition system, the motorcycle still wont start, or rather sometimes i can get it to start after kicking it 78 times, then struggle to get it to idle, then struggle to keep it running, then it dies. If you are thinking about buying one of these motorcycles, don't. Even if you get a killer deal on it like I did, free on post dated barter, you will be gravely disappointed. even if it runs when you get it, the carburetor will fail, you will struggle to find a comprehensive rebuild kit with ALL the parts, and even when you do, it will probably struggle to perform as it should. I hope you don't end up like me, with a gorgeous restored motorcycle with low miles and a clean title; and literally sit there with a tear in your eye and look at all the hard work you've done, listen to the other motorcyclist ride by, and think to yourself i wish i never would have acquired this motorcycle. &%$#@! you Yamaha. One customer lost. Thanks for the &%$#@!ing paperweight.
