  1. That is a cool road. First time I ever rode it we followed the marked state route 119, down Tower road into Careyville. Next time across we stopped at Shea and looked to the left, wondering where that road went. Nice road, at least until it turned to gravel about halfway up the mountain. Came out about 4 mile north of Caryville. That was first year Tina was riding, she didn't have quite enough experience to know to be scared of the rocks, so she did fine. She later told me if i could do it, she could too. I hear the prison is closed now. Wonder where they moved James Earl Ray to? This it? Pics from 1995
  2. Wish I still had my 61 auto 2 door, or my 64 Spyder convert, or my 65 Corsa. Yea those were the days.
  3. 3 days easy. 2 days ride if you wish. 1day if you are serious With the exception of the jaunt from Surgoinsville to Tazewell on their route, and Grayson Highlands State Park to Sugar Grove we have ridden those roads. Not much after Abbingdon for motel or fancy sit down restaurants, until you get back to Mtn City.
  4. Is that the road that takes you up Brushy Mtn, past the prison?
  5. With the recent turmoil in the credit card industry they have started closing accounts of people who pay off their balance on the day they receive the bill. We had one canceled on us while we were out of town. When we called the card company we were informed that the account was closed by them, they were restructuring all accounts with a zero balance. The fact that I had that card for 10 years and never once was late on a payment did not impress them. I have read about lots of other people having their cards canceled just like me, and for the same reason--zero balance
  6. Those are pretty cool. Would look really cool with a piece of dark tint plexi-glass behind them for summer rides.
  7. Hot spoon eh? I need a little more clearance in my HJC for my melon in a couple places, I'll try the hot spoon thing. Good idea.
  8. I put "progressive" springs in the 86 last summer, $100.00+- a couple. Probably one of the best things I ever did for the bike, just over 3k miles on them and I need to change oil. I now need to address the rear spring. It has just as much, actually now more mileage than the front did. If replacing both springs at same time I'm sure it would be a totally different bike
  9. You are absolutely right George, it is not necessary! And neither was the crack made earlier by Stoutman. So I'll sit down and be quiet again.
  10. This is an excerpt taken from the book called "Ultimate Guide to 11 meter(CB) antennas. Not that i wish to call you wrong by standing by your answer, but, to only illustrate what I was taught 39 years ago in electronics school. I'm reasonably sure the theory has not changed. Why does my coax length affect the SWR of my antenna? How many of you change the length of your coax to tune your antenna? One of my good friends said to me, "I think changing the length of the coax is the same as moving the gamma rod adjustment on my Moonraker 4". Sorry to say, this is not true. As most people will find, varying the length of coax to the antenna will vary the SWR that the SWR meter is reporting. Actually, SWR should remain relatively constant no matter how long the coax is or where it is placed on the line (if its 5 feet down the coax from the radio or 50 feet down the coax from the radio). In most cases, the cause of inconsistant SWR meter readings is from poor SWR meter design or component aging / failure. For the SWR meter to read consistant SWR readings on the coax, the meter has to have an impedance itself of exactly 50 Ohms. Any deviation of the SWR meter's self impedance (from 50 Ohms) from poor design or component aging / error / failure will cause slightly inconsistant SWR readings when the SWR meters position on the coax or length of the coax is varied. In practice, generally you will find varying the coax length seemingly effects the SWR reading. Most SWR meters (built into radio and external type meters) and impedance "humps" in coax lines and connectors will cause minor variations in SWR as jumpers and coax length are varied. In reality, the mismatch at the antenna's feedpoint / coax junction is unchanged. Therefore - the actual SWR is unchanged. Another reason SWR could vary is from the situation where the coax is acting as part of the antenna. Not a favorable or normal situation. The signal is traveling back down the outside of the of the coax braid (note power should only be traveling on the inside on the coax braid). Therefore, the coax is part of antenna system and changing the coax length will change the SWR. This situation is more likely to occur in mobile installations. You can try to eliminate this situation (called "Common mode currents") by winding an "RF Choke". Wind about 6ft of RG-213 or RG-8 into a coil (6 to 8 turns). For RG-58 use 4ft with 6 to 8 turns. Wind the coax up, placing each turn right next to one another. Use electrical tape to secure turns together. You should place these as close to the antenna as possible. Right at the antenna coax connection point being optimum. Most times, you can verify that you have common mode currents flowing back down the coax by grabbing hold of the coax while transmitting and moving the coax around. You can watch the SWR waver by moving the coax while transmitting (don't speak into mic!). You have to do this with all the doors closed from inside the vehicle. SWR should waver, if you notice that SWR jumps rapidily between two values, you might have a intermitant (bad) connection in the connectors (PL-259s) on the coax. In most cases of "common mode currents", just grabbing the coax will cause the SWR to change.
  11. DING, DING, DING! We have a winner. If cutting the coax changes your swr then your antenna is not resonant any way. If the ant is not resonant then it will not matter if your coax is 1meter or a full 11meters long. A much better way to check antenna is with an analyzer, swr is just relative to the amount of power you feed it, and analyzer will tell you if you have a true 50 ohm load and what the swr is at the frequency you dial in.

    Actually it is more simple than you could imagine. The joint is place on the trailer tongue with the cross going straight up and down/ left and right. This part parallel top the ground gives it the up and down float need to go over bumps and suspension to work up and down, and the part of the cross perpedicular to the ground allows the left/right turning. So it is used only as a pivot and not as for rotational alignment

    Wonder if the wind you feel is because the mount is so far above the center of gravity of your bike?? That is same color scheme as the 86 I have. When it shines it is a pretty color, wish mine was blue though
  14. link does not work
  15. WIsh you would have posted up you were coming to Ky also. I would have enjoyed riding with you on Sunday. Could've possibly even made it Monday
  16. Well, no wonder you only rode 800 miles. You guys stopped every 15 minutes for those Kodak moments:rotf: Seriously, nice ride, the more you ride that area the more you grow to like it, if that is possible. Last trip across the skyway I saw something I have never seen before, any where. Wild hogs running down the edge of the road.
  17. That would be very good. It may have even saved me at least one or two times of pulling the carbs offa the Royal Star TD. There would be plenty demand for a dvd that covered a several areas. Just being a specific dvd for one item, like for carbs and another dvd for suspension would be quite cumbersome for us less talented folks.

    Setup; We have a weight of 100 pounds centered on a frame that is 7 foot long. For this application each end is supporting app 50 pounds, presuming the load is centered correctly. And not accounting for the weight of beam holding load. For simplicity, given that we’re interested in load per support, we’ll assume this to be a point load. If you moved the center of gravity (load point) 3.5ft to right side, then you’d have 100% of the load on one leg and zero on the other (theoretically, and neglecting weight of beam). What if we move this 100 pound, 1 foot to the right. We now have 4½ foot of frame sticking out the left side and only 2½ foot on the right If you move load 1 ft to the right of center, you’d have 100lb acting at a distance of 2.5ft from the right end that produces a moment (torque) of 250ft*lb. The reaction force on the Left end has to produce an equal/opposite moment. So 250ft*lb / 7ft = 35.7lb. Because the two reaction forces have to equal the applied force, 100lb load – 35.7lb on the Left = 64.3 on the Right.
  19. Or, you have something on the rotor such as a spot of grease or brake fluid. That will cause the brake to chatter, as will the spring clips on the caliper being missing or broken/bent.
  20. Those "eyebrows" are the coolest.

    Would that equal distribution only be true if the tongue and the distance behind the box were equal? If the center line of the tire is 12" behind the box and the tongue is 24" ahead of the front of the box would it not work much like a wheelbarrow and give you a proportionately lighter load on the tongue?
  22. we'll either ride 75 to Ktown and down 129/321 to Garlinburg, motel for the night and ride to Cherokee and start up the parkway. If so, we'll likely make Stations Inn or Mt Airy, then cruise home across Hawks Nest on Sunday. Or we'll go to Asheville and spend the night and up the parkway on Saturday. haven't looked at weather forecast yet, so this may only be one of those rides we wanted to do again.
  23. My wife rides a Vulcan 800, she won't even ride the Venture with me any more, she would rather pilot her own. 800 are pretty easy to find and cheap. I have an extra one if you are even slightly interested.
  24. Is the road still closed from just north of Ashville to Little Switzerland? Tina and I are contemplating a quick ride Friday night to Cherokee, and spend Saturday getting to Mt Airy, then Sunday riding home
  25. 99RSV? What happened to your wing?
