Hi, I need a smaller rear sprocket for my gy200-2.

Does any one know where I could get a cheap rear sprocket that would fit this bike . I would like the sprocket to have anywhere from 42 to 46 teeth. The bike currently has a 56 tooth sprocket.

The bike seems good but to get it to go 50 mph you have to have the RPMs at around 8000 rpms due to the 56 t sprocket. This seems a bit high, so I usually only go 45mph at 7300 rpms.

The only problems I have had with the bike so far are that 2 of the rear engine bolts broke. I put different ones in and they seem to be holding.
I get a lot of vibes around rpms of 4500 to 6000. Higher than 6000 the vibes seem to go away.

When the bike was first started I had to screw down the throttle cap to the carburator and adjust the Idle. After that it has run well.

Bruce at EJcycle will send you a sprocket fast. 330-274-0098

I have a 45 right now and I can easily cruise at 55mph.
