I just did the throttle body oil pump synch TSB on my sled. The 'new" Polaris TSB stated to align the oil pump mark and the arm mark .050" on the fat side. I went about .030" eyeballing it. I rode 284KMs about 165 miles last weekend and burned enough oil to give me a 69:1 gas/oil mixture. I am thinking I'll fatten it up a hair to get closer to 60 to 55:1. Running Amsoil Interceptor with a slp big air kit- Haven't got the reflash done yet. What do you guys think? Also does the reflash get rid of the hesitation around 5000-6000 rpm?
