Hi Maxim, I am using the base settings that you provided me with a while back. I have richened the needles by one notch and am using 185s in the bottom cylinder and 183s in the top. I have not had the opportunity as yet to give the bike a blast. I am SORNd until spring time. My probs were due to the bottom piston burning through its crown, this has happened twice and I am now on my third piston. My 21 is a road bike and I am running with my oil pump. I am hoping that with the HRC kit fitted the extra availability to "tune" the carburation will elliminate my piston probs.
