Hey everyone, as you may have read in one of my previous posts I had an issue with my 3 wheeler not wanting to take mid throttle. I have since changed the carb which now allows the trike to idle as well a great improvement in power and throttle response and the mid throttle problem went away. Well earlier while doing an oil change on my 3 wheeler I also decided to lube the chain, and check all connections to make sure they were good. That said I noticed that my airbox had become detached from the carb. So I reattached it and put everything back together. Once i did my post oil change once over, I decided to take it for a short ride thru my yard. During my short ride I had noticed that the mid throttle problem had returned with the reattachment of the airbox. So I disconnected the airbox and took the trike for another ride and the problem disappeared. Does anyone know what could be the cause of this? What are my possible solutions to fix this issue. Also the airbox looks to be a sealed type. There is a metal part that I believe is attached to the air filter but not sure how to remove the filter. Runs great with out airbox but not with the airbox. Thanks again in advance and again sorry for the length,Bill
