2017 Bashan Enforcer 250 and Bashan Storm 250 assembled.

[china007]

So I assembled both bikes which were easier then I thought. They ride completely different and I noticed a difference between the counter vs non counterbalanced engine. I'm currently changing the oil on both. The carb issue was a pain at first but then I think it set in good when adjusted. The battery went dead on the enforcer and when I tried to remote start it it kept trying to start before I disconnected it. I charged battery back up and no problems. Do I need to change carb on these 2017 models or are they good.
