I had a problem with my CS Twin while completing running in. Email below explains resolution. I am impressed that CS are standing behind the one year no-quibble warranty they offer on their web site.

Dear Mr Peng

The OT Twin engine I recently bought from you has been damaged. I need to return it for service.

I believe I have sheared the drive from rear crankshaft, to the coupler which engages the front crankshaft.

This occurred possibly due to over compression of one cylinder. I will exercise great care in future.

Please reply to this email and advise whether I should send the engine to your Zhengzhou office, or to your Shanghai office.

I look forward to hearing from you.

Regards
