The 450 de-tent spring took care of the two false neutrals I experienced in my first ride on the bike. I called over to a dealer in Canada and received the de-tent spring in about a week. Installation was semi easy and the shifting was like any other bike I have ridden.
The spring I took out out wasn't putting any pressure on the shift drum.
When I removed the bolt that holds the spring it had no compression, it stayed in place and came off easy.
The 450 spring puts a good amount of pressure on the drum. I had to have help putting the stronger spring in, one to hold the spring in place and the other to tighten the bolt. So far I am expecting a very good riding season.
