vahanger Posted January 9, 2011 Posted January 9, 2011 Hello everyone, And thanks webmasters for helping me out,was a bit lost indeed..well like I was saying hate to jump right into a question ,If I could would come over and have a beer or two lol...Anyway I bought this 1980 Yamaha 175 mx for my son to ride or at least to give it a try hoping he loves it as much as I did growing up,So this bike is getting fire although it is very weak ..note new plug and boot was bought.The manual says for the coil that the primary value for ohms should be at 1.0 +/-15% .but mine says 0.0 and the secondary is at 6.3 but says should be at 5.9 +/-15% But im use to a 4 cycle where you throw a little gas in the cylinder and if i hear it trying to start then theres hope ..lol..The compression seems good but havent done any leak down testing,Oh by the way I did noticed something splashing around in the cylinder and turned the bike upside down which out came maybe a pint of water,,that did concern me but to look down in the carb intake the bearing looks good and clean and did not see any rust.The carb was real clean also,I tried starting with some gas just put straight into cylinder, and with just the carb itself and not even a puff or clue, if it even wants to start..anyway if anyone can give me a new clue or guide I would really appreciate your help.and so would my son ! lol!! Thanks! Oh, I helped my wife get her 1975 Honda CB 200 going several years ago,So I just got to help out the son now..Thx. Bruce.
