When I upgraded my air filter to a velocity stack + UFO style the other day I found that my bike ran a bit ****house. So I dropped the clip on the needle and found that it ran better slightly richer however at WOT the engine would die. There were no weird noises or anything associated with this, the engine simply cut out until I backed off the throttle. In order to cure this I hunted around for some larger jets but didn't really have much luck in finding anything so being the impatient ******* I am I found a 1.0mm drill bit and ran it through the jet with my fingers.
I figured that was probably going to be way to big and cause problems however that was not the case. The engine is running great now and is pretty good at WOT but it still feels like it is running a little lean. A check of the plug after a good 20km or so thrash has revealed it to be a bordering on a light tan colour whereas with my old setup it was always a dark grey. Is it possible I need to go larger again? I only doubt myself because everyone else seems to be running such smaller jets in their engines even with setups like mine. What do you guys/girls think?
