Hey @Spartacus Stroppel Welcome to Quadcrazy. I’ve tried the China carbs. Here’s my take. They look great, exact same as far as appearance, have all the sensors and choke set ups. But they don’t work 100%. There are flat spots in the throttle when you ride, any time I’ve tried them (twice) it’s been where I would say 80% good.
How can the seal kit be so expensive for the oem carb ? Have you checked eBay and Amazon? Also eBay for a used oem carb?
