New Hydraulic Brake Master Cylinder for 90cc 110cc 125cc 150cc 200cc 250cc Go Kart Buggy Sunl BMS Kandi Roketa Kazuma Kinroad ATV

Did not fit my Joyner 250. To be fair I don't believe it is listed in the description but the Joyner 650 is, which I believe use the same master cylinder. Seems well made but would not use. They do not have it listed but the rear of the master cylinder that goes into the frame, the round part where the plungers go in, is too big. It is about 1.5" and my stock one was just a tad bit smaller. About 1.3". I was going to bore the hole out but then it would be too close to the holes where the mounting screws go in. I ended up taking it apart and using the parts to rebuild my old one, but be warned that the reservoir will not fir if you have a 2 piece master cylinder. The mounting holes are in the 12 and 6 o clock position versus the 3 and 8 position. Other than that everything else fit fine and seems to be well made.

Brake fluid pores out from underneath the resivor cheap Chinese made product

This does not fit SUNL bUggies. Even tho it’s listed in the description. I was able to use it in my sunl but it was not a direct swap. I had to use some old parts from the old master cylinder with the new one.

Worked perfect only had to modify the go kart mount slightly

Worked like a charm. No leaks.
