banshee67 Posted May 9, 2010 Report Posted May 9, 2010 i have stock carbs with tors and toomey needles. i was considering boring my carbs but i was have heard that if you bore them too big that air will leak and that you will never be able to jet them right again. i was wondering how big you can go and if the power blades will help power. any help will be appreciated.
