Peter-
No you shouldn't have to rejet unless you remove all 4 baffels from the stock slashcut pipes. After the 4th baffel came out of mine, Yep definatly.
Removing the snorkle does give the carbs more air, No Doubt about it, Yank that sucker. You may have to adjust your mixture screws (under the carbs) after you do this because you will need a squirt more fuel in the idle circuit.
Hope this helps.
