There in my welding shop hangs a sign that reads . We have no quarrel with those that have a lower price for they alone know the true value of the work they produce .
I`m just guessing here but I would think that the 600 cc bike you linked has a lot less removed from the bottom as it has a lot less to begin with . I could be wrong . as soon as Ivan posts his numbers for my 1,000 , I will be happy to look at them , evaluate them and decide if it is for me...
most experience no change to better than stock mpg`s . fwiw I installed Ivans kit for an aftermarket exhaust and airbox mod . it rocked afterward . so smooth !!!
am I the only one here that likes the sound of the exhaust as I roll off of the throttle and get that repeditive pop sound ? I have read of so many riders jumping through hoops to get rid of it:chat:
