900rr exhaust ixil slip on
I have a question guys and excues the lack of knowledge and know how. Only been riding for about year and the 919 for about 3 months.
I have installed the 900rr exhaust with and ixil slip on. After install I feel the bike has lost power. I have not had it tuned but am concerned.
Do i need to have it tuned? Will a power commander fix the "tuning issue" so i can save some money? And will I have to live with the "lost power" ?
