I have recently bought a shineray 150cc street legal dirt bike and the exhaust is way too loud for rides more than 5min i was thinking of replacing the exhaust but the pipe is very unusual size outside is 9.5 which divided by pi roughly estimates to 3cm in diameter but i couldnt find any exhausts in that size. And i have noticed the carburetor needs to be cleaned or replaced since it runs only with the choke on. Is there any suggestions where i could find an exhaust and carburetor on taobao (I am currently in mongolia right now and i could order stuff from taobao)3CD19330-11CD-4D56-A773-6FD1321CCABD.jpg
