Hi everyone, I'm new to the Yamaha Owners Club having recently passed my test and bought a 2002 Thundercat.

Bike is lovely BUT it's just developed a problem with the rev counter.

Issue is as follows:- Rev Counter now revs to 8K only(on the clock but bike rides ok)and drops back to zero and does this regularly before showing the right revs for a short time then dropping to zero again. Also I have noticed the needle moves to 1K and back to zero. When it does this zero to 1K range the bike has a minor hicup(a sort of miss or jolt).

HELP Please anyone got any idea's of what the problem could be as it's now becoming a pain.

Cheers

Floyd, make sure you go to the newbies section and do a full intro...we like the noobs to do this.

As for your problem, i'd sy 90% that is a TPS fault. Loads of Yamahas do this is to show either the TPS [throttle position sensor] is either out of calibration or is faulty. Don't worry that is anything to stop you using it - it's just one less signal for the ECU to read and make adjustments too.

This would also link to the hiccup you are experiencing, though that could be something else.

HTH Thanks for the reply will check the TPS out. Very Much appreciated
