HI guys, just wondering if anyone out there is adventure riding on anew early WR450F?
I have not long bought an 04 model and just got it registered and back on the road but are having issues that are driving me bonkers and are almost ready to put a for sale sign on it and cut my losses!
I never noticed it in the dirt but on the road as soon as it gets warm it misses like crazy at a constant throttle, I have been through the carb and confident it's not a fuel problem, I have replaced the battery and checked the stator and rectifier both cold and hot and all good and cleaned all the plugs and checked the wiring.
I have narrowed it down to either the TPS, CDI or ignition coil, if I unplug the TPS the problem is almost gone but is a little flat at light throttle. Some of the forums I have read say that on the road at light throttle the WR's jump back and forth between two different ignition timing maps in the cdi, the consensus seems to be just unplug the TPS while on the road throwing the CDI into the ignition map for wide open throttle (hence the flat feeling at light throttle ) and plug it back in when they get into the dirt.
I am not that fussed on this idea, constantly unplugging and plugging in the plug are going to wear out the plug and break the wires (and no doubt when I am miles from anywhere), I also think this is probably a bit of a cop-out.
So what I am asking is...... dose anyone else have this problem or had this problem as I understand that there are quite a few of these bikes adventure ridden here in NZ?
Otherwise anyone interested in an 04 WR450F registered but more suited for the dirt? Hahaha
Any advice is greatly appreciated.
