HDDOCFL, I guess this can stay as intended, just an exchange of good ideas & information & "opinions" . First if you happed to notice by the details provide at the bottom of every one of my posts I am not running the stock factory lame di*k 9.1 compression you are, I am running 10.5 compression with the other mods listed, I have neither the time or inclination to make my case further with you,, but when you take the position that two Jagg coolers are not required with no technical data to support such a statement (other than your "opinion") it does upset me, as you misinform others that look to this forum for up to date information, not misinformation. When you get a chance pick up a copy of Donny's Peterson's "Unauthorized Technical Guide to Harley Davidson 1936 to Present Vol: 2 Performancing the Twin Cam" He is only the world's most read technical journalist & an acknowledged "expert" by the engineers @ MOCO on HD motors. Very informative, especially the whole chapter on oil coolers & the whole chapter concening all the problems that our 110 motor as had from 2007 to date, with suggestions for corrective actions. (Problems which I might add MOCO has never publicly admited to) Only after you are better informed then I'd don't mind hearing your opinion, as again eveyone has a right to their opinion, but when you express it when you are not informed and it is not based on any measureable data or research then it is a disservice to others on the forum that are looking for better ways of doing things. Have fun with the bike, if you see me on the road please wave, I'll be the one running those silly two Jagg coolers.
