Well we all know these bikes are a little harder to start them most. I can start my 88 kx5 cold 1st kick almost everytime, but when its warm it takes at least 3 good kicks to get her going. any ideas as to why this is? also I have been running kawichem 32.1 in the bike since I got it, but was thinking about switching to amsoil, they say run 50.1. Anyone else use this oil?
