Works better than expected! The jet I've been running for years was a 118 and I was very lean. So I purchased this kit. I tried the 130, and lost all top end and ran way over rich. I think I got maybe 35 miles outa one tank of gas! I then tried the 125 and then ended at the 120. These jets are very different than what I had before as these are tapered in the inner area which I believe to allow more fuel or to maybe spray it wider. My previous jets do not have this taper and there is a HUGE difference in 118 to the 120. I think this kit the 120 is actually more equal to a 125 or 128.After I settled on this 120 I adjusted my needle clip down one for richer mix and now it's a whole new ride! Faster accel, more top end! Top speed currently about 68 straight 72 with the wind. All on a STOCK 150cc block.
