I have a 1995 GL1500 w/an unknown model Lehman conversion, 72K miles. Bought it used last April w/ 42K miles. It has always had just a tiny bit of "shaking" in the fairing at highway speeds, but of late (last 8-10K miles) it has gradually become more pronounced. To the point that I can't really tell what I am seeing in the mirrors. This "shaking" is not always present. It can occur solo, two up, pulling a trailer, no trailer. It comes & goes gradually. There is no sudden starting or stopping. High wind makes it worse sometimes, but not always. When it is not present, wind doesn't seem to cause it to start. I can feel no shake or vibration in the bars & no "wobble". I do sometimes have a low speed (below 20 mph) head shake that is easily controllable with one hand. Super Brace installed. The triple tree says Trike Shop on the top. I assume it has more rake than stock, but have no way of knowing how much. My guess would be no more than 4.5, as it is not particularly easy to steer. (compared to my Valk trike which had 8*) Windscreen is an F4 +4. Makes no difference if it is raised or lowered. Shocks normally have 52 PSI when two up pulling the trailer but raising or lowering pressure doesn't seem to make any difference. Front tire is a BT45 reversed, approx 6K miles, 40 PSI. Rears are General Altimax, 20 PSI, Approx 4K miles. All tires have beads in them. Any thoughts as to where I might look for the cause? TIA. Stan
