I just installed the street twin, works great and I love it. How do I do this break in? Can I go WOT and just not shift hard? I heard 500 miles is a good guide.... It doesnt seem like it would break it in though if you just went 500 highway miles.

 

NO NO NO on the WOT. You need to do a lot of shifting and smooth easy take offs to bed the disc to the pressure plate and the flywheel.
When we did the SPEC stage 3 in Rods TT Formula on the first drive he got into the boost just a little in 3rd and the clutch slipped. After that he drove like he was supposed to with a new clutch and after 500 miles it holds 5500 rpm clutch dumps on the boost.

 

Man the hardest part about the clutch install is the break-in. I didn't mind laying on my back and holding the flywheel while I ran bolts through half as much as I mind not going WOT for 500 miles But its worth it. Like AL said, there's resins in the friction material that need an EASY break-in period to properly seat. Otherwise, you will glaze your disc and it will not hold like it should. McLeod reccommends "500 miles of easy stop-and-go city driving" for the break-in. That was on a sheet of paper inside the clutch disc box when I bought my Dual Performance set. I still have about 20 miles to go on the break-in, and you can see how the clutch improves over the break-in period. Launch real easy, no slipping the clutch. Shift slowly, and don't take it above 3k.

 

How are you supposed to launch easy without slipping the clutch?

 

Just quickly but smoothly let off around 1.5k. Don't "pop" the clutch, but don't slip it too much either. Of course, it will always slip a little during engagement/disengagement, but from what I've heard the Street Twin is more of an on/off clutch anyway.

 

I hope I didnt ruin it... I was slipping the clutch a little just to smoothly get going.
