Getting ready to do some upgrades to the Attak GT. Have gotten some mixed advice about rear susp. as far as doing both Fat Boy spring and shock revalve. A guy up here I trust alot says just do the revalved shock. Of course the dealer recommends both. I also got the 13mm bar up front and do the bushings while in there. Got some nice Yamaheaters too. I'm about 210 pds Winter wt. What's most cost effective, so I have some $ left for the Phazer II...

I ran it last year, with stock susp., set on stiffer side and only thing I noticed was some chatter in some stutter bumps. I was told when doing the rear shock, to shim the rear too. This was one I had never heard before. According to our buddy Scott, those rears get quite loose. I hope not as bad as the A-arms and bulkhead up front...
