julien Posted February 11, 2012 Share Posted February 11, 2012 Hi guys , Julien here , Things are going yamanuts at the moment ,yamahas are coming at me from all sides. Along with the 2 yamms i got recently , a friend of mine has got me tinkering with his xs250 . I'v sorted the carbs and now it runs sweet as a nut ( this bike is suprisingly good fun ) but after about ten minutes it starts to cough and splutter and has flattened the battery . It will do this even if you dont start it with the ignition left on . I know my mate has messed with the wiring as he has bobbed this bike so that could be it , and i will go over all the wiring when i get a mo' but does anybody know how to check the generator ? Probably a bit of a pain to explain to a numpty like me I know, but it would be much appreciated . Im crap at electrics . My parents are coming out to spain in a week with a suitcase of DT175 bits so I can make a start on my project . Will keep you all up to date with that as it hapens and try and get some pics of the progress. Link to comment Share on other sites More sharing options...
Moderator drewpy Posted February 11, 2012 Moderator Share Posted February 11, 2012 get a multimeter and run the engine to 3k revs. across the battery you should be seeing 13.5 - 14.5 volts don't know how old the bike is, if you have a mechanical voltage regulator, you can adjust the output. you need good battery or it won't charge. check out my rewire in my blog (hint, click on my signature) further info in the classic section sticky or www.xs400.com Link to comment Share on other sites More sharing options...
