pilninggas Posted August 28, 2010 Share Posted August 28, 2010 Hello Booney, It would be really good if you could go introduce yourself in the general forum. Unfortunately we have lots of users who join up when they have a problem and disappear afterwards. I'm not a mod or anything, but this does negatively affect a good forum! Anyway 3500rpm rev counter. Does the rev counter drop to 0 when the ignition is off? If it doesn't, the rev counter itself is goosed (or maybe possible to free with a disassembly and rebuild). If it does it when the ignition is on, it may well be the TPS (throttle position sensor), these were a known weakspot and the bikes were recalled for a replacement. Yours may have slipped through the recall (check with YAM UK or your local dealer) or the replacement may have failed. You could test the TPS yourself, however these fail via -nonlinearity and so it may not show up with a multimeter. Other than that i'm not sure. regards PG Link to comment Share on other sites More sharing options...
Booney Posted August 29, 2010 Author Share Posted August 29, 2010 You are right, where are my manners! Stuck at 3500 all the time. When ignition is turned on it flutters a little!? Perhaps I'll try and take it apart when I can get a workshop manual. Booney Link to comment Share on other sites More sharing options...

I see possible resolutions to the fault, mines stuck on 7000, did the diagnostic check on the TPS, suggested range I believe is 15 to 97, mine results are 14 & 96, out by a fraction. A call to Yam dealer is called for, temp gauge also stuck just below halfway, digital side of the dash seems in good working order. Link to comment Share on other sites More sharing options...
