I was about to post a question related to my difficulty starting the R90/6 cold. Well, I was playing around with spark and gas issues. Yesterday I decided to check my valve clearance. I was sure the right side wasn't right. I pulled the valve covers and lo a behold the left side was too tight. I set the clearance to .006" intake and .008" exhaust. At this point the bike was still a little warm but it seemed to run better. Just to make sure it was running better I took it for a 150 mile run.
This morning, with the garage temp about 60 degrees, I set full choke and tried it. It started right up. Yippee!
I think I nailed the problem and I'm no mechanic. I love this bike!!!
