10/40 vs 20/50 Another oil thread

[flavor]

Aren't you sick of oil threads.......

I changed my oil last time with half 15/50 nd the other half 20/50 last oil change. I know that's weird. Anyway I noticed that when starting the bike I had to use the fake choke until the bike got warmed up a little. Just changed the oil again today and used spectro 10/40. Didn't need the choke.

Weird ha.

IMPO I think the bike likes 10/40 better.

PS. With the 10/40 in the RPMS seem to come up faster.
