I just bought a CFORCE 600 Touring, and the dealer wants me to bring it in at 100 miles for the first service. I just read the manual and it says 20hrs/200miles, which includes the valve adjustment. When did you do your 1st service? Also, you did the valve adjustment? I haven't done one in about 20 years, did you just read the manual? Or did you watch something on YouTube? Thanks for any info, just trying to figure out if I am going to do the service myself, and when. Just for context, I used to be a machinist mate/mechanic in the Navy, so I can turn a wrench, I just don't do if very often anymore.
