After fruitless efforts to get Tech support to tell me where the CDI is located on the XPro Eagle 110cc 4 wheeler, I finally found it!! NOT under the seat like most 4 wheelers, of course. It is under the cowling over the left front wheel.
When the new 4 wheeler was delivered with an additional CDI and no (zero) instructions as to what it was or what to do with it, I started researching. Called the company in California and was told to send them a service request on line and they would respond with an email. After multiple emails and receiving no helpful information, I looked one more time. Pulled the plastic insert off the left side of the body. It looks like a scoop. Lo and behold, when peering in through that opening, I found both the fuel petcock I had been looking for as well as the CDI!! This is a video I took showing the location for the rest of you who might be having the same issue! Hope it is helpful. Enjoy!
