Making some progress and getting an understanding as to what I have. So today I took the head into the shop, cleaned it up a little and cc'd it. 90.0 cc's. Conservatively it is .045 down the piston, gasket bore 4.200 x .039 and a 4.375 stroke by a 4.125 bore and I am using 1 cc for the two valve reliefs. That yields a current compression ratio of 9.73. From what I have read, S&S claims the 117 from 2006 is 9.6, so it's close enough to determine that the compression portion is of factory, it appears. Tomorrow I will get the camshaft out. The cylinder heads have triple springs, a titanium retainer and a larger intake valve than that of factory. It measures 1.990. From what I understand, the factory valve is 1.940. Prior to actually getting the cam out to identify it, I would just make an assumption, that why would anyone just put triple springs on it and not have an aftermarket cam. Cam and applicable valve springs go hand in hand. This is starting to make sense as to why it's sluggish. Too much volume and not enough static compression to match the camshaft which would make the engine at a loss for cylinder pressure. Lack of cylinder pressure gives weak air speed, and from that weak air speed, the inability to shear fuel, and it does have a lot of what I call "fuel deposits" on the back side of the intake valve. I'll just keep plugging along and get this whole puzzle figured out.
"Boy it sure is a beautiful bike and the candy apple is exactly what I wanted. Do you have any receipts or history on the bike?" "All I can tell you Andy is that it has a new ignition/harness because the bike cut out on me and it also has an upgraded clutch and some engine work and the shop that did it is extremely reputable and is very knowledgeable about these bikes". "Do you know exactly what was done"? "Not really Andy." "Ok, i'll take it!" lol
