i got a 14 with my 18's and its good. im going with a 38 rear because of a new big bore kit and carb so that will cancel out the loss of low end for me, but for you, you will probably lose alot of low end.

a big front sprocket and small rear sprocket will give you your top end speed back.

Where can I find a smaller rear sprocket ???
I already have the 14 front but its not enough

you can get sprokets pretty cheap a vitospeformance.com

projectblaster.com sells a nice PBI 38 tooth for the blaster. i just got mine and its worth the money. that or find a renthal anything cheaper will wear out in no time.
