greeneggs and ham Posted July 17, 2013 Share Posted July 17, 2013 Hey, I wonder if can help? I went for a ride the other day and as I reached around 60 mph my bike seemed to drop power for a split second and then a warning light come on! It stayed on till I stopped, turned engine off then it flashed 4 times then off then 4 flashes again. It almost seems that a high rev makes the light turn on. I changed spark plugs, air fIlter and changed oil and filter to boot! Still seems to happen? Any ideas out there? Link to comment Share on other sites More sharing options...
Ttaskmaster Posted July 18, 2013 Share Posted July 18, 2013 You're supposed to take it to a dealer and pay 1 hour of labour for the minute it takes to decode this. However... "Apparently", there are only two fault codes listed for the XVS 3 blinks for the TPS and 4 blinks for the speed sensor. Since I don't know of any speed sensor on this bike and because the symptoms sound like it - I'd expect the issue to be the Throttle Position Sensor, or more likely one of the wires from the TPS in need of checking. There's a few YouTubes that show how to test the TPS. In case you don't know, it's Part 45 in the Carb schematic here: http://www.cmsnl.com/yamaha-xvs650apapc-2002_model11085/partslist/B-02.html#results Link to comment Share on other sites More sharing options...
slice Posted July 18, 2013 Share Posted July 18, 2013 It's always the expensive bit and never the cheap bit that fu**s up isn't it!!!!! Link to comment Share on other sites More sharing options...
greeneggs and ham Posted July 18, 2013 Author Share Posted July 18, 2013 Thanks very much man, I did go to a dealer and the guy advised me to go somewhere else as it was £80!! I will have a look into these and hopefully will have it running nice again!! Link to comment Share on other sites More sharing options...
Ttaskmaster Posted July 18, 2013 Share Posted July 18, 2013 Did you test the TPS and the wiring around it first? Did the dealer also check the flash code, or was that what the £80 was for? If you need a new one, check eBay. Like this: http://www.ebay.co.uk/itm/00-2000-YAMAHA-XVS650-XVS-650-V-STAR-THROTTLE-SENSOR-36-/330940168216?pt=Motorcycles_Parts_Accessories&hash=item4d0d923818 Chances are Yammie used the same one on other bikes. The V-Max uses some of the same components as the Drags, for example. Part numbers may help, too. Link to comment Share on other sites More sharing options...
greeneggs and ham Posted July 18, 2013 Author Share Posted July 18, 2013 I haven't checked the TPS yet, will look over the weekend. The £80 charge was just to see what was up with the bike, he said go somewhere cheaper. This was only a few days ago. I'll post up how it went and see If it solves the problem!

gizmo666 Posted July 18, 2013 Share Posted July 18, 2013 i've never done this so have no idea if it works but if you remove the battery for an hour this will "reset" the system when you refit the battery evrything will be back to normal as said i've never done this but have heard it works suppose theres nothing to lose Link to comment Share on other sites More sharing options...
greeneggs and ham Posted July 19, 2013 Author Share Posted July 19, 2013 Sweet well ill try that first! Thank you very much! Link to comment Share on other sites More sharing options...
greeneggs and ham Posted July 20, 2013 Author Share Posted July 20, 2013 So I unplugged the battery for around 40 mins yesterday just to see and rode to work today, I must say it seems to have improved! No light came on and it didn't seem to struggle, quite amazing how much power was lost. She seems a lot happier now. Thanks for you help guys!

Russbiker Posted July 21, 2013 Share Posted July 21, 2013 fingers crossed the problem doesnt come back! Nothing worse than intermittent faults. Youll be watching out for it for ages long after its fixed Link to comment Share on other sites More sharing options...
