I suppose it is possible that your tube is folded or pinched inside the tire, causing major imbalance. If you think this is the case, you should immediately take the wheel apart and check. Trust me, you don't want to experience a flat tire. Some degree of bouncing is to be expected with a spring type nose gear leg, but that's way more than I have seen. Check your axle bolt tension while you're at it and make sure your wheel is rotating freely. Also check your nose fork breakout tension. If it is too loose the wheel can wobble violently from side to side just as it touches the pavement. Use a fish-scale to actually set it per Vans instructions. The fork must have a good bit of tension and not just swivel freely. If you can't find the culprit, I would give Vans a call and see if they have any further clues. ________________________________ Message 2 _____________________________________ Time: 09:54:44 AM PST US From: Leland Subject: Re: RV9-List: Windshield Frame --> RV9-List message posted by: Leland I know an RV6 builder who used sheet metal on the front of his windscreen for the same reason. He intends to redo it the future but it looks great to me. This guy is a real perfectionist, the best technician at a government Lab, and a superb craftsman. It is also the third plane he built. I would try it as I had such a bear of a time with the slider canopy skirts that I finally made those out of fiberglass. Leland in Kalifornia Almost ready to install the windscreen "I visited a local builder who had fabricated an aluminum panel at the base of the windshield and along the canopy frame on both an RV-6A and -7A. It lookedvery nice and neat and he said he did it because he didn't like fiberglass (Iunderstand that!). It was screwed in place to both the cowl and the screen andsealed with silicone. Has anybody else done this? I'm considering doing thisbecause of the neat appearance and also I think replacing a cracked screen would be infinitely easier. Any thoughts out there in RV Land?"
