No good in a 400 engine. You need to use 10w/40 or 15w/40 mineral oil

Too thick for a 400 gear box pump

Thanks for explaining Trigger. I recently replaced 2 of my K6's carbs with better condition ones, bought as a bank off ebay, complete with gantry. I replaced the brassware, so all 4 were consistent with 105 mains. Relived the jetting is the only difference on the later bikes.

Thanks Ted,so for an old worn motor, like a 1960s Mini,a 50 grade is OKFor a modern tight clearance motor, a 5 is OK for cold startsSo,would a 5 x 40 be ideal for our sohc motors?If no,why?Sent from my SM-A546E using Tapatalk
