Thank you I didnt know about the colortune. I will research it

But will you need 4 colortunes?

Why do you want the cylinder temp low though? As long as it doesn't overheat it's fine, right?

@@reneverheij6938 depends on how you ride the Yamaha fjs. They are air cooled and running them lean to get more power means they run hotter. Out on the highway at speed this is fine. However if tuned lean and ridden slowly in traffic on a hot day they can over heat and cook rings and valve guides. So running them on a slightly rich mix keeps the temps in the safer range when doing slow riding on extreme hot days.

@@carsonharding9852Makes sense! I try to never get stuck in traffic jams with the FJ. I kind of want a temperature gauge so I know when to shut it off in time.
