This is a little premature,but some of you know I tried the amsoil in my 03 kx 250 a while back at 50:1. I was not impressed with piston inspection after 50 hrs. I ran klotz r-50 at 40 :1 looked much better and mobil mx2t look the best at 32:1.
To prove my point on oil ratios, is bike and rider specific,I am using amsoil again at 32:1,I just finished off a gallon of oil 32 gallons of gas (16 tankfulls)and Pulled my pipe. At 32:1 the amsoil is very very clean,the powervalves were spotless exhaust port clean as a whistle.The piston on the exhaust side looks very well lubricated,infact it looks the best I have seen compared to other oils and definetly looks better then running it at 50:1.The rings looked beautiful sitting in the grooves,nice and juicy no blowby whatsoever,not even the top ring.I did have some light carbon build up in the pipe which is very normal,but to my suprise I used my index finger and it fell apart like fine dust.
I am not judging this oil until I have enough hrs to tear it down,but so far I am very impressed and I will prove my point with pictures. I have pictures of the pistons using different ratios especially the amsoil at 50:1. I will get back after a few more hrs on this top end.
