BlueTaz100-

What did you end up going with? Let us know what worked out best for you.

I am buying the same setup you have, and want to know how it went for you...

sorry i haven't posted any findings i haven't had much time lately but i haven't done much testing but the next size up from the stock 148 that my brother inlaw had on hand was a 158 so i put it in and when we both ran it, it seams to pull strong all the way to the rev limiter, i have to watch because it will hit the rev limiter real fast in 1st 2nd and 3rd it doesn't seam to have any bog or hesitation i haven't done a plug check because i had just installed a new plug and figured it would take awhile to get some color to it
i still have the air box lit on but got a outer wear cover for it but haven't put it on yet as i haven't had the time to ride but when i get to play with it more i'll let you know and i hope this will help someone else out
