Interesting....I too have the tors, by-pass, k&N, ....what is the snorkle business?........
The dealer put on the tors before I got the bike and told me they loaded the "off road" tune. Have since put on the by-pass and K&N...service mgr said it was fine as it is and would do not harm, but would check it if I liked.....got a tech to the the side and he said there is another tune which is better.....and the K&N makes no difference at all.....also indicated the company is sending out additional tune maps, the latest for some cold starting problems....will be taking it in next week and see what they come up with.
