Did you know that every new Harley sold in Canada comes with a standard snow shovel and chains for the tires? And did you know that the entire country of Canada has at least 6 feet of snow every month of the year and some places in Canada have 100 feet of snow?
Oh, forgot to mention that we all live in igloos and it is always at least -40 below.....
Well, that about covers the cooling issues!
No one has mentioned cams in this thread yet. Getting ride of the AWFUL SE 255 cams with all of their early-on compression due to their very short intake duration (211) will allow the bike to run noticeably cooler, by improving the breathing and reducing the cranking pressure.
I used to run the Andrews 54H cams (238/238) when I had the Fullsac X-Pipe and 2" baffles (GREAT setup!), and now I run SE 259e cams with the Drago's S/C/S-4 2-1 pipe because the big Drago's pipe really needs the long duration (246/250) of these cams. This setup is LOUD... and I mean VERY LOUD! Just low growling tones tho... no tinny high-frequency noise.
Now that the Andrews 57H cams are out, those would be great with the X-pipe, too.
