Hello and I hope to address whether a Timken Conversion can be done on a 2008 FLHT. You see, I have been planning on a build since I purchased the bike in July of 08. I have been following this forum shortly after the purchase learning about the newer Harleys. I have ridden since 1975, owned Harleys continually since 1982, a Sportster and a 1985 FXWG. While some items may seem to some unnecessary or even unwise, here is my list: Pistons Wisco Cylinders 107” Revolution Performance Cam Andrews 54HG & Gear Kit Pushrods Crane Adjustable Chrome Moly Rocker Arm Roller Rockers Crane Feuling (Combo Kits) #7074 - CamPlate, Oil Pump, Lifters Exhaust Thunderheader #1054B (2 into 1 Long Style) Air Cleaner K&N 63-1122 Clutch HD Heavy Duty Spring Ignition Zippers ThunderMax Heads Dewey heads. The bike tear down started today. I also was going to remove the crankshaft, have it trued and welded along with the timken conversion. I was having a discussion about it and was told the newer models could not accommodate the conversion due to the sprocket shaft being a different diameter. And I would have to purchase the S&S version. This is the first I have heard of this. Can anybody verify this? Had the timken conversion on a 2007 or 2008 touring model?
