FZR AL Posted October 30, 2010 Share Posted October 30, 2010 Help needed my fzr600 is acting up will not fire on 1&4 changed the plugs,coils,caps still the same any ideas? Hezzy Have you fuel getting through , if you pull the plugs and ground them do they spark? are they wet ?, could be compression , could be ECU , if you have a multi meter , work backwards from leads until you find power, it could be earthing out somewhere have you had the bike long, has it just started do it , really need some more info great bike the FZRs got a 89-90 3he , what you got Link to comment Share on other sites More sharing options...

hezzy67 Posted October 31, 2010 Author Share Posted October 31, 2010 FZR AL Fuel is geting into the pots went as far as changing the carbs fuel lines and filter.Plugs spark when grounded changed the cr9e standard plugs for iridium ones.Compression seems ok engine had a full strip down and rebuild with new gaskets last year only managed a few hundred miles since through work.ECU was changed for a spare,Had the bike for 3 years now bought as a project was in a right mess when I got it half finshed body work,engine in bits,looked like it had minor crash damage on the plus side got loads of spares with it Bike is early 89-90 3he Link to comment Share on other sites More sharing options...
Moderator Airhead Posted October 31, 2010 Moderator Share Posted October 31, 2010 so you say it sparks 1 & 4 with plugs grounded. I think sparking when under compression is more difficult so to test this can you put a strobe lamp or a spark tester in line on 1 & 4 How about a possible pick up coil problem...got a spare?
