disconect exhust valve, install powercomander, MIVV pipes, now this bike rocks, over 120hp at wheel so goes like it looks. I've had mine for 2 years now.4 year old bike, only problem ive had was loose wire on fuel pump relay, which caused bike to cut out, otherwise very reliable, 20,000ks, handles and brakes very well, poor fuel economy and range, but fun factor worth it, very happy to have it.
