James1983 Posted May 27, 2016 Report Share Posted May 27, 2016 With bikes I always start with all the basic (cheaper fixes) and rule them out first... Filters Plugs Battery Fuel pump Not sure on the YBR 125 but my Suzuki had a diagnostic mode where you put a wire to bridge the two pins on a connector and it gave you any fault codes which you could easily get from the web might be worth checking if yours has similar as the bike could tell you what's wrong and save you hours of trial and error Quote Link to comment Share on other sites More sharing options...

Longman Posted May 27, 2016 Report Share Posted May 27, 2016 Does your bike live outside? If so check your fuel tank for water, I've worked on 2 of them that had faulty petrol tank seals and you can get water in the fuel system which causes this type of problem. You should also hear the fuel pump prime when you switch the ignition on.. Quote Link to comment Share on other sites More sharing options...
