You didn't mention what year/model Monster you have so this info may not be relavent, but
if you have a 00-02 M900ie there is no 14T front sprocket available for conversion from the factory 15T. 00-02 MY 900's require a flanged sprocket unlike any other years and (so far) no aftermarket companies nor DP have produced a 14T to fit in place of the factory 15T countershaft sprocket. If you have one of these M's as I do your only choice is to add a few teeth to the rear by changing out the rear sprocket for a larger one and fitting a correspondingly longer chain.
