gy 125 info needed pls??

Ok my gy 125 has been sat up all winter needing a few little jobs done to it.
Now most of those little jobs are finished and the snow has finally melted im desperate to get back out on it :riding:.
I need to ask a few things though first of all could somebody tell me if they know the diameter of the carb at the engine inlet side. Second could somebody tell me the diameter of the exhaust(im thinking of cuting the rear can off and replacing it). My bike is a bog standard run of the mill lifanoid gy 125.
Thanks

So many of these bikes have mix and matched parts, your safest bet would be to take the measurements yourself. A simple set of vernier calipers is only about 10USD and can be used for all kinds of important measurements on bikes.
