Crash 142 said:I tried one on my 03 CR250. It helped bottom end, but it really hurt top end - I had to jet it way, way leaner on the main - about five sizes down! In my opinion, it was not worth the trade off, and I took it out. I played a lot with jetting and couldn't get the bike to run as well on top with the Power Now in there.
