Probably need to step up to a LARGER size JET but manufacture should be able to give you an idea of one, or two size increase.
Also Air box Changes affect Jet requirements.

Your plugs will tell you if rejetting is really required. Good idea to make "before pictures" for that.

Unfortunately "just pay shipping" is no favourable option in my case. :roll:

@scar1: i was eyeing that muffler as well. Did you mount it already? Since you said you are willing to give yours for free, Id like to know how we can accomplish that. :) Im on the other side of the world but I have a secondary shipping address in NY to help me forward it here to where I am at. If its not much to ask, can you show me how your pipes looks like? i will appreciate if you can shoot me a pic through email.
