I'm thinking about getting scrappys 15t gears for my 150 my revs are a little high with 13 gram sliders and my koso variator and the gears aren't much more than a set of Dr pulleys. Was wondering if anyone has scrappys set and if they do how do they perform, my stock gears are 13 40. And I'd think the scrappys are 15 38 not sure on that since it doesn't say.

Just did this exact swap lost a lot of rpm same change 13 40 to 15 37. I too had a high tach but I lost a lot of rpm with this swap. Bike will go faster but takes longer cuz the motor has to wind up longer to reach power band I have stock 150 cc with big valve head that raised compression 1 point to 10:1. 10 gram sliders blue torque spring and 842 belt. Overall I like the gearing cuz motor is not reving like crazy at the top end.
