    Great buy!
  

*by J***. on Reviewed in the United States on June 5, 2016*

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.
