From all I have researched I think I might have found a solution. I bought my EVO kit for my older motor a long time before my racing season started so I could get an advantage on time. After a side by side with another kart who bought their kit later than mine (2 weeks before the season to be exact) I found out that their kit had some components (possibly wiring) that my kit was lacking. Later in the day another driver who purchased the kit around the same time I did experienced extreme RPM loss and ended up having the same problem. I then came to the conclusion that the “older” EVO kits are failing and need to be replaced. I am currently in the process of getting a new kit and will post again if the problems do not show themselves again.
