Stock roller is in 33 gram.
I will have dyno results once I also get my Variator from Malossi. My dyno guy will be winding down the Dynos for the racers and will have time, probably next month, I hope. I will keep everyone posted with the results as they come.
it's posted in the gallery. the Power didn't increase much but the output was more stable and felt stronger. the stock clutch has more shoes but you could see it didn't contact all the pad. The dr pulley locks in with the pillow blocks. I won't really know till I get a few thousand on the road and put on the dyno again to see the seated clutch again. The HP went up and the Tq went down. It.s only 2hp up to 52 and .6ftlbs down. but remember thats at the wheel. the biggest problem with it getting dyno'd is that it goes thru the gears and you cang keep ine gear to perform a proper test like a normal bike. By the way, the Dyno is stock weights versus Mallosi mixed weight (22/24 gram) with 3500rpm engagment. the lighter wieghts were just not very streetable.

Say what??!?
Here's an update. Brought the scoot back. Had the clutch springs changed. I went for the red springs. No more noise. Fantastic! It's a different bike.
Just ordered a set of Dr. Pulley 28 g rollers and sliders and will get them installed at my next BMW service (10 K) Looking forward to see the kind of changes you guys described in the previous posts.
From the Dr. Pulley website as per the link on the first post. They shipped the next day after receiving my order! That's German efficiency for you!
