  1. alright! you guys helped me out a lot already!! yeah looks like that 1974 carb is the same as the 1975, i think its the same for 73-75 after looking through that yamaha parts guide. that makes figuring out where to find parts a lot less mysterious hehe. if this carb is still at this one shop im in business
  2. damn how do you come to know these things?? i found a 74 yamaha tx-500 in a salvage yard out of state with both carbs and they are parting/shipping regularly, im tryin to find out if this carb is the same carb as mine and from the pictures i've found it LOOKS very similar, but the '76 500xs carburetor looks like 99% the same to me except it is missing a port with a jet and i know thats a major difference, so if this '74 carb is the same i can get it
  3. original service manual came with it carb is keihin cv32 (two) .. i have ONE of them but its missing parts so blah from what i've gathered they used this carb for the '73 tx500 through the 75 xs500b and in '76-'78 they used a different carb. been hard to find online i probably need to find a junked bike
  4. so in my quest for new carburetors, is it possible that the same carburetor is used on other bikes or other engines made by yamaha?
  5. hey thanks for the advice! carburetor's are near the top of the list, i only have one carb body and only 1 jet! so i did some looking and found some, but my budget for parts does not get refreshed until the end of july! upon inspection the gas tank has old nasty gas in it and there is SOME rust, but not as extensive as i expected after 30+ years in storage mode last time this bike was registered was '81 hehe. So yeah, i plan on doing a complete teardown, but as u and my friend indicated its probably best to wait and try to get it running first to see what i need to replace, but the frame has too many rust spots and in the end i hope to have this bike both running AND looking well so in the meantime i will just clean all the accessible parts of the oil and dirt (its all over im sure there was a leak somewhere) until i get the funds also, the front shocks are hydraulic and certain they have a massive leak cuz they are coated in this yellowish oily fluid and the rubber seal around the top is cracked and i could pull back a flap super easy and yellow fluid drips. hehe here i will try to post photos of its "before" state heh so as you can see, where my carburetor should be i have a cloth! the guy had one partially assembled carb in a box but no jets and the float? i think its called seems a little sticky. it may take a long time but will b a fun project
  6. hey this thread is gonna help me a lot, i just bought the same bike 1975 xs 500 for 180$ yesterday! it needs a lot of work as well sorry im not much help just wanted to say thanks for the thread and good luck
  7. Hey everyone, my first post to go along with my first bike i bought yesterday: a 1975 yamaha xs 500b it does not run i think the wiring is not hooked up right from what the previous owner said. i bought it to have something I will post many pics later on... It needs a lot of work i believe, but I have never worked on a bike or actually any engine although i am familiar with the idea of how they work. I know i will be replacing many parts but im not exactly sure how to determine which ones need replacing... It came with the repair manual, have not referenced it (and title of course)..So after getting the bike the biggest problem i have is where do i start? I have read some other posts for project bikes even for my exact bike as well and will reference them a lot im sure. How do i know if i need to rebuild the engine? the ODO is broken, so idea on the miles, covered storage for 20+ years... the guy that sold to me got from his ex-wife's family and did not know much about its history, but he did say the engine would turn over, which i gather means it is not seized up? which may indicate that the engine does not need the rebuild? The chrome parts have rust spots but i have not investigated to the extent of the rusting, but in general can i use sandpaper superfine grit and what phosphoric acid gel stuff? Should i just start taking apart each system now? I read a post saying to take apart each system, clean the parts and wrap/box/label it and just work on fixing each system one at a time... The bike is pretty dirty in general, i kinda feel like the easiest thing for me to do to get familiar with it is to just take it completely apart and clean all the crap and rust off then see where it is thanks in advance
