So I've tried all the different belts, including the Mitsuboshi OEM one from treats, and I still slip when I hit around 43-5mph. I've still got loootttsss of RPMs left to go. I can tell because the engine revs way out as soon as it slips, and my ear dyno says I'm maybe 2/3 of the way thru the pipe. As soon as I let off the throttle, I can feel it hook right back up and I can accelerate for a sec until it happens again.
Bike setup is polini kit / oko 24 / Vforce / TJT / DOS ramp plate / simo calibrata pipe
What are you 60mph Hobbit people doing? Ramp plate spacers? Grinding out rivets in the pulley?
Give up your secrets plz!(edited)
