I have an 08 Apex MTX, last year I put on a Camo extreme 162x16 and changed my top gear to a 19 tooth. I did the gearing at the beginning of the season and it seemed good, but after I changed tracks In the early spring, it seemed I was hitting my rev limiter constantly. The clutching is all stock, what would be a good setup for me, I ride 2-3000ft mostly and boondocking is my style of choice. Thanks for any input.
