They been cleaned only once and the 125 main jets where changed to 120 mains I purchasted new from Murphs aprox. one year ago. many feel the 120's provide better jetting than the 125's Asking 160.00 plus 19.95 shipping. Total to your door 179.95 payment can be sent to jtrento@tampabay.rr.com via paypal .
