I know this has been beaten to death and yes, I've done a little bit of research but I still have two questions regarding the switch from stock to stage 1. What exactly will I be loosing when I forfeit my auto-decompressor? Is it just that it would no longer be a good idea to start the bike with my flip-flops on? Second, a guy I met at the local track (Washougal- and yes I run the BRP at Washougal on practice days and surprise alot of people when I pass the on one of the table-tops) anyway, he said he had changed to the stage 1 cam with great results but needed to take the bike to a local shop for installation because the cam had to be "pressed" in. Looking at my service manual, I see no procedure for pressing anything in and to me it looks like about a two hour DIY job. BTW, I mostly ride ORV trails here in Washington state, which by the way are like a German Virgin....Goot-und-tight!!
