Year: 2013 Model: XL1200C Miles: 15000 miles on fluid:10000 Fluid used: Red Line MT-90 Stock or modified: Engine, intake, exhaust all stock clutch type: Screamin' Eagle Performance Clutch Kit-38002-04 Performance clutch kit converts the 8-plate clutch to a 9-plate design. The surface area is increased by 13%, and the spring rate is increased by 10% for a combination that can handle over 115 ft-lbs of torque at the crank. Kit includes Kevlar®-based friction discs and performance clutch spring Trans fluid history- 1000 mile service - clutch adjustment HD SYN3 used 3150 miles - new Screamin' Eagle Performance clutch installed - HD SYN3 fluid 5000 miles service - clutch adjustment Red Line MT-90 fluid (this UOA) Blackstone Comments- There's some extra metal and silicon here, but we're thinking that those are just residual materials from this transmission's wear-in. The high wear is from the parts developing their tolerances, while the silicon comes from harmless sealers used during assembly. A lot of this should wash out with this change in fluid. Universal averages show typical wear levels for this type of Harley Davidson transmission after ~5,700 miles on the oil. The viscosity was a bit thick, but we don't think that's a problem. Check back to start building trends. My comments- I haven't found very many Harley Sportster transmission/Primary UOAs. Another Forum lists a couple. The Red Line MT-90 should have a 100 C viscosity of 15.6 cSt. So it didn't thicken, it sheared just a little. I'm not sure if Blackstone was thinking it was Mt-85, 12.0 cST, or MTL, 10.4 cSt. The dealer did use a little silicone on the clutch inspection cover gasket when the clutch was installed. Maybe they also used some on the Primary cover, I haven't taken it off. This run was started with about 2000 miles on the new clutch so a little more iron from the new steel plates wouldn't be unusual. I ended up with about the the universal averages for iron with almost twice the miles.
