If the CHTs are truly that high and have been for a while you should have symptoms... The first symptom of high CHT is tight valves. If you don't have symptoms and it hasn't scattered yet, I'd question the validity of the data. CHT is fairly unaffected by ambient temps, while oil temp is heavily impacted by ambient temps. Of course, non-temperature compensated CHT gauges can send false data in cold temperatures. This post has been edited by Jake Raby: Nov 28 2013, 10:00 PM |

Thanks Jake, I did not put too many miles on it as I was watching it closely and followed your advice about letting itgo through it natural cooling cycle and not cooling too quickly. It has been cold here but with the change in jetting I saw an immediate impro vement with the same ambient temps. |
