Thinking of changing from a stock 35 tooth sprocket to a 33 tooth sprocket. Or a 35 tooth to a 37 tooth (rear sprockets). How will these changes effect the performence on a polairs outlaw 90. I weigh about 145 and race hare scrambles

 

slightly faster on smaller sprocket,slightly slower on larger sprocket with a little better pulling power.

 

Will the smaller sprocket effect low end or take off? How much speed will i lose with the larger sprocket? thank you

 

On a 90 you wont notice much difference either way. Not trying to discourage you,but the old saying is no replacement for displacement! If it was a larger displacement engine then you could notice an appreciable change,but you are dealing with a small out put engine and regearing will only make a slight difference either way. Good luck
