I didn't say what type of oil i run in the 125. i just said the ratio. T2 is pre-mixed at a 40:1 ratio with a top quality JASO FD-rated. The fuel comes already mixed from Vp. In the 250 i run Cam2 110. Works good for me.

I've used Maxima 927 at 32:1 since 1983 and I've never had to clean a power valve, I really dont know where that myth came from.

was a bigger issue with the gumming on the 125's. actually with the 250, i run a hotter plug and it burns pretty clean. a little rich but still chocolate brown. no complaints.

You didnt have to.
VP has one oil and you have to figure thats what they are mixing in.

So why are you technically ass backwards on both?
