I probably should have said in comparison to the way it was before
or that I do not notice it. I do feel heat if I put my gloved hand on the motor.
I think you fail to realize that the sportsters run significantly cooler than the big twins and that the cool collar will not do close to what a flow through cooler will accomplish on any bike. You should by all rights feel heat when you put your gloved hand on the motor if it has been run recently.
I know I am new new to this site but just about everything I have read here has been just people's opinions without any proof or data to back
it up. Some of the information is wrong without anyone bothering to see if is valid. Just re posting what someone else wrote does not make it true.
I would like to ask you here to show me some posts that were posted with incorrect info in them that you can verify was incorrect.
We try to dispel any bad info on the forum so that the members will not be lead down the wrong path and make mistakes that will be passed on to the the next person. If you notice that in regard to your post, that I replied that I saw no difference in the installation on a friends bike. That was tested using an oil temp gauge and I do not have the numbers written down but I do know that there was such a small difference in temps that it made the purchase of this unit a waste of money. The flow through units that will make a difference because of the air flowing through the core of a multi cored unit are worth 10*+ reduction in temps, but a simple heat sink will make little or no noticable oil temp difference that is noticable. The next question is would this unit be worthwhile getting as a little difference is better than nothing....only you can answer that.
I personally would go for a flow through unit as opposed to this cool collar if I wanted to remove some heat from the oil and have it work efficiently.
I would like to bring up another point here about the chrome covers that are used to dress up the voltage regulator. These have been the cause of more than one regulator going bad because of the air flow being diverted from the fins of the regulator to cool it. When I compare the theory of this voltage regulator cover to the heat sink effect of the cool collar, maybe you can point out the difference to me so that I can understand where it is?
I have only just started working on bikes, basically for the past 35 years or so, but I am willing to listen and learn to any and all theories about bikes and how the related systems work aside from what works better than others.:hii I look forward to your reply.
