r1 loon Posted April 20, 2008 Share Posted April 20, 2008 HI CAN SOMEONE HELP. I HAVE A 2004 YAMAHA R1. IT HAS CREATED A MISFIRE. WHEN THE BIKE IS ON THE STAND IT RUNS SWEET. IT GETS HOT AND ALL THE USUAL THINGS HAPPEN FAN CUTS IN AND EVERYTHING. I TAKE IT FOR A BLAST AND THEN IT STARTS TO MISFIRE AND THE ENGINE MANAGMENT LIGHT COMES ON. THE FAULT DOES NOT CLEAR IF I TURN BIKE OF AND RE START. THE BIKE NEEDS TO COOL DOWN AND THEN STARTS AND RIDES FINE. THEN IT WILL START TO MISFIRE AGAIN AND THE MANAGMENT LIGHT COMES ON AGAIN. I GO THROUGH THE DIAG PROGRAM ON THE CLOCKS AND THIS KEEPS RAISING DIFFERENT FAULTS I CLEAR THEM AND GO FOR A RIDE AND IT BRINGS UP MORE FAULTS. I HAVE SPOKEN TO YAMAHA AND THEY ARE TELLING ME THAT THE RECALL FOR THE TPS HAS BEEN DONE, IT WAS CARRIED OUT LAST YEAR. CAN ANYONE HELP ME AS IM GETTING TO THE END AND DONT KNOW WHAT ELSE TO TRY. THANKS R1 LOON Link to comment Share on other sites More sharing options...

THANKS R1 LOON Sounds very much like a coil breakdown, if you can next time it happens swap the coil leads and the wires for the coils over and see if the cylinder affected changes ? ifnit does you will know its the coil and you can change it! if it does'nt you are looking at coil pick ups or cdi unit ??

r1 loon Posted April 26, 2008 Author Share Posted April 26, 2008 Ive had a V&N baffle kit fitted into my standard exhaust can. i have today changed the cans back to the original one and i have managed to ride it today for 50 miles and it was ok. i have tucked it away untill the next sunny day so hopefully i might be able to test again. if it goes tits up i think i will be taking a trip to wallingham. im a bit miffed because im not sure or why a baffle kit would make the bike do that. does anyone no why this might happen???????????????????????????????????????????

yoda Posted May 6, 2008 Share Posted May 6, 2008 well i went out again and the misfire is still there. i getting ready to put this bike on the scrap heap please please can anyone help Have you changed all of the spark plugs? If so then you need to change the engine management system. Before you do that, take it to a dealer and get it computer checked. Link to comment Share on other sites More sharing options...
r1 loon Posted May 6, 2008 Author Share Posted May 6, 2008 Have you changed all of the spark plugs? If so then you need to change the engine management system. Before you do that, take it to a dealer and get it computer checked. i have changed all of the spark plugs and all of the coil packs, i have even changed the sub loom. im running out of ideas. i have spoken to yamaha and they have told me that there is no other diagnostic check other than the one that is on the on-board clocks. i just dont know were to turn with this bike. sometimes the fault will come cylinda 4 but it is actually no1. im also sure that this is going into limp mode but this does not reset when you turn the bike of and re start. im starting to think that it is the ECU. If it is the ECU then i would have to get complete new key set and ECU which will cost an absolute fortune so i will have to scrap it. I dont even have the red key so it makes things worse. any help would be good. so far i have changed.......... TPS/Coils/sub Loom still no change. this can happen anything from 1 mile up the road to 50 miles. Link to comment Share on other sites More sharing options...
yoda Posted May 6, 2008 Share Posted May 6, 2008 Does this happen at any engine speed and does it happen at a constant throttle setting? Link to comment Share on other sites More sharing options...
r1 loon Posted May 6, 2008 Author Share Posted May 6, 2008 Does this happen at any engine speed and does it happen at a constant throttle setting? been out on it today after cleaning all of the injectors out and the throttle bodies and seem to be fine all the time i was riding slow. as i gave it a fist full over 9000rpm it stated again. i limp the bike back home very slowly and by it was on my drive it was running fine. there is something strange going on...
