[QUOTE="Gary Gittleson, post: 103957, member: 3625"] I am the "USA-based friend". The springs were actually over-sized when I got them. According to Mr. Timetraveller, they were supposed to be 16" but were actually 1/2 inch longer. That caused the forks to simply lock, at least with my 165 lb weight and no fuel tank or seat on the bike. I cut the springs down to 16" and all seems well. It's amazing how much difference that 1/2 inch reduction in preload made. The bike is fitted with a Thornton shock with the long eye bolts. The Thornton has some 7,000 miles on it and can easily be compressed by hand. As I mentioned to Norman, there's no chance I'll be trying the bike for a while. The weather hereabouts is too awful to discuss in polite society. Once I test it, I'll report the findings. [/QUOTE]
