Default Re: what did you do to your motorized bicycle today?

After drilling the jet out to 0.8mm (no good) I had to fix this.
I soldered up the jet and drilled two 0.5mm holes, which works out to about 0.7mm.
Goes awesome now. Nearly no 4-stroking (prob need 0.65mm or so). Plug is dark grey instead of wet black. This is so critical, 50 times improvement!
