Bill, Ferret here (Mickey), and I have a question for you.
I have one of my menu items set as coolant temp. The other day I had it on that page and noticed the coolant temp fluctuation like crazy so yesterday I rode for 26 mins at an ambient temp of 42 degrees and switched to the coolant temp page. I was on a flat, straight highway going 63 miles per hour steady and pulled out my cell phone to record it
Over the next 2 miles (2 mins 3 secs) my coolant temp gauge read in order 159,158,154,156,159,163,172,145,143,149,158,163,168,176,147,141,143,154,163,176,174,158,140,147
Does this sound normal? One would think the coolant would reach a given temp and stay there unless accelerating, going up a hill, stopping for traffic etc ie: different draws on the motor, but not going flat same speed same temp.
Am I worrying about nothing?
have you tried it on your 18?
