I have my shocked turned to stiff and run high air pressures in the O.G.'s, you will get your setting right after you upgrade the tires.
I don't use a programmer with a 660, but many here do run one with their injected bike and most use Eric at E.H. Racing.
And when you are doing the service, I suggest you check and set the valve lash.
I agree on the exhaust pipe thing, but used the 2" tip as it gave the 660 a faster response, not more power. If it was quieter that would be good, but its not that loud now and the noise is behind me.
as for spacers, I don't use then as around here we have 50" gates limiting trail access and spacers make the bike too wide. As for the bearings, others have reported the spacers out extra stress on them so let other report on that.
