im on 7000 miles on a 06 cfx 700, still runs strong, comp is 120 both sides, and is still a virgin.. i bought the cat top end kit for it this fall, but it runs soo nice i really dont want to touch it, ... but if i dont, with my luck, i will drop a skirt, and have a major.. so i guess i will tear it down now while its still cheap..
My m1000 has 9000 on her. Never opened the motor yet. Some say im crazy but why fix it if it aint broke. 140 psi in each cylinder and barely any blow by. Its on its second primary though.
mines about the same as the OP (4k+) and i have no intentions of touchin it. it still runs great and is probably one of the strongest runners in our group. now if only i had some snow to ride it in
Got 9800 on my one thousand, just replaced the exhaust valves with supreme tool valves, nothing else done to engine, run delete oil injection, pre mix is amsoil interceptor 32:1
