  1. 5K is a bit early for the 2nd gear issue. Yamaha used a soft thrust washer on the transmission shaft that has the 2nd gear slider on it and it tended to wear a bit and then the transmission would hop out of 2nd gear. ALL the bikes made before the middle of '85 had this problem. My 83 made it to about 75K. Another thing you might want to do if you get it running is to pull the rear tire, and then the shaft drive unit and grease the drive shaft splines with heavy molybdenum disulfide grease. If it only has 5k on it, it may NOT have the updated alternator stator cooling modification. This was a recall done twice. My first stator only lasted about 7500 miles before it became grounded. Yammie replaced the stator and installed the first version of the modification. A few months later, everything was fine with my stator, but they came up with a 'better' cooling mod. and they replace the stator again and installed the new kit. The 83's had a weak frame and the cross bracket that the rear shock attaches to twisted. My frame broke at about 90,000K. I replaced the frame with one from a 84 which was way stronger where it broke. My brother is riding my 83, and it is running fine with 140,000 miles.
  2. I've had this identical problem with both of my 1st. Gen. bikes. The first time I had it, is was on a trip and had ridden most of the previous day in rain. After a bit the bike ran real rough, but if I gave it full throttle, it would run better for a little bit. I put up with the poor running all the way home, and by after about 300 miles it was better. Then I was going into work at 3AM and it got real bad. I fought with it and by that afternoon I was pretty convinced that it was water in the tank. I pulled out the fuel filter and blew it out putting the contents on my driveway and you could see the water separated from the gas. I pulled the petcock from the tank and drained the water out of the bottom of the tank. Then I opened the carb. drain screws and drained the carbs. Once again I could see water in the gasoline drained from the carbs. Put it back together and it ran great. A couple of years later, I got caught in a gully washer, and the bike began to run rough again. When I got home, I had to drain the water again. This was before there was 10% Ethanol in gasoline, so water would just lay in the bottom of the tank until it was drained. I figured the only way for rain water to get into the tank would be through the vent. I traced it's path and saw it was right in front of the rear tire and as gas was drawn out of the gas tank, a vacuum would form and it would draw some of the water that was was in front of the tire, which would go up into the gas tank. I cut a slit in the vent hose so that a strong vacuum wouldn't form at the lower end of the vent hose. I never had problems again, until I purchased the 89. I hadn't had this problem for so long that I never did anything to prevent this on the new(er) bike. My wife and I were on the way to Maintenance day and on the Ohio Turnpike it rained hard for a bit, and the bike started missing. I knew what was wrong but couldn't do anything where we were, so we just soldiered on. Now the gasoline was mixed with ethanol, and could absorb some water. After we filled it up with fresh gas, it got better. After the 2nd fill, it was mostly cured. By that night it was fine. After we got home, I cut a slit in this vent hose also. To verify if you have water in your tank, pull the fuel filter, hold it vertically with the filter element up, and then blow through it (using a hose) on to a hard surface. Look at what's on the ground and if you have water in your tank, you should see some mixed in with the gas.
  3. What is your issue with the clutch?
  4. How is the radio interfearance (RFI) with this lamp? About 6 years ago, I had an LED headlight installed. The light was OK, but after we moved 70 miles SE of Nashville I noticed that I couldn't receive hardly any radio stations. I found that interfearance from the LED headlight was making it difficult for my radio to receive weaker stations. I'd appreciate it if somebody who has one of these SuperBright LEDs installed could tune in a weak AM and also a weak FM radio station with the key in the accessory position and then turn the key to ON to bring on the headlight and see if you notice interferance.
  5. The antenna on the left side in the pictures is a television antenna with a rotor. Because it looks like a higher gain antenna and has rotor, I suspect you live between 2 cities a few miles away. Did you get the rotor control box? The antennas on the right mast are PROBABLY for 144MHZ (aka 2 meters) and the other probably for 440 MHZ (aka 70cm). I can't tell too much from the pictures, but If you pull them down you could find the model number and I could tell a lot more. They look like there are mutliple antennas in each giving them higher gain. The mast looks like a 'push up' mast so if you can see how to release the sections you could release the guy wires (on a calm day) and then lower the antennas down one section at a time. I can't tell for sure from these pictures, but the wire that has an insulator on it and is attached to the TV antenna mast 'might' be a dipole antenna. Just a length of wire with a coax cable attached to the middle. None of these are worth a lot of money, but the 144MHZ and the 440MHZ antennas probably cost $100-$200 new. You may be able to sell the push up mast too.
  6. Chief, This is a bit off topic, but....Failed lifter & cam (replaced) and the latest BIG issue was a failing of the final drive bearings or gearing. If your engine damaged a lifter and camshaft, you had metal particles in your engine oil circulating through your engine and transmission. The oil filter would have caught most of them, but some would have gone throught the filter bypass on a cold start. This may have been the cause of the final drive unit/gearing going bad and getting a new engine was great.
  7. Yes, shaft drive units on 86's and later are different than the 83. The parts diagram shown has #30, #31 & #33 circled and I thought that the seal you had problems with was the seal coming out of the middle gear unit. The seal I had to change on my 83 was the midde gear seal and I also replaced it on my 89 when I replaced the U-joint and yoke even though it was stil dry. Sorry about getting which seal wrong.
  8. The only thing I can tell you is that I did change that seal on my 83 and had no problem doing it. The seal came out easily. I will tell you that depending on how many miles are on your bike is that you may want to replace the universal joint now. On my 83 the grease in the universal joint had dried up and the cups were galled at about 100K. On my 89 with about 80,000 miles on it the grease had dried up and the universal joint had worn to the point that one of the bearings had come out of the cup. If you decide to replace the universal joint be advised that it only come with 2 caps.. You have to buy the other 2 caps separately (#35) and also 2 ea. of #37. I think I bought the yoke with the universal joint. If you don't replace the universal joint at lease disassemble it and inspect and grease it.
  9. One thing I should have said is that the reason the vacuum gauges are moving so violently is that the only time there is flow through the carb is when that cylinder is on an intake stroke. Then the vacuum is high. When that cylinder is on a compression, ignition or exhaust stroke, there is zero flow through the carb and the vacuum is zero. I seem to remember that the gauges will indicate about 9.5" of vacuum when all the carbs are synchronized properly. This reading is on my First Gen, but Second Gen should be close.
  10. To read the intake manifold vacuum, you need to restrict the hose to the gauge so that the vacuum at the gauge can average out. I've tied knots in the hose near the engine and then just adjusted the knot tightness to restrict the vacuum signal. I've also taken a 1/2" bolt, and drilled a hole in the bolt big enough to pass the gauge hose through. Then you thread a nut onto the 1/2" bolt adjusting it to restrict the vacuum signal. You could also use a needle valve to restrict the vacuum signal. Whichever method you use, when you have the engine running, you should see the gauge moving a tiny bit. When you shut the motor off, the gauge should slowly move to zero.
  11. The 83's (and also later) Ventures do have fuel shut-offs. It's on the right side of the bike, at the bottom of the fuel tank. As memory serves, on the 83 Ventures, the shut-off wasn't accessible without removing the right side main cover. Look at the lower part of the cover, and below the very bottom of the black section is where it's at. On the 84's and later Yamaha put a notch in the lower edge of the cover so you could get to the shut-off without removing anything. When you turn the shut-off you've got to be careful or you will break the actuator, especially if it hasn't been moved in a long time. I think I'd spray it with something like WD-40 and let it sit before moving it gently. You may want to also check and make sure that it's turned to "RESERVE" so you can use the full capacity of the tank (5.4 gallons). Get this fixed immediately. You have a very dangerous situation. Gasoline fumes can explode. Any spark or even your gas hot water in your garage tank may cause ignition. Also while turning off the shut-off is a good idea, if the leak is small it'll take a while for the trapped gas to run out. What I would do is to put the bike on the center stand, remove both side covers, and get down and inspect the fuel line from the shut-off, thru the gas filter (under the gas tank) into and thru the fuel pump (also under the tank). If you don't find any evidence of a leak, follow the red hose up to the carbs. One clue might be does your fuel pump run quite a bit after sitting for a few hours?
  12. On my 83 I used to get about 20,000 miles on the back tire, and after I trashed the first coupling/driveshaft, I started pulling the back wheel at about 10,000 miles to replenish the grease. At 10,000 miles, the coupling was almost dry. I started out using a quality wheel bearing grease and switched to a thick moly grease. There wasn't a drastic amount of difference.
  13. I never setup a VHF or UHF rig on my bike, but I do remember reading an article in QST many years ago about a ham that rode his 1200CC Gold Wing to Alaska and back and operated HF Morse Code while riding along the Alaskan Highway. I went to the QST web site (ARRL.ORG) and did a search for it, but all I could find was a mention of the article that said that it was in the July 93 QST, but their archive only went back to 2000. The article I found today did say that it was a 10,500 mile trip Frank D. KA9J
  14. Taking into account that we live in middle TN. about 70 mi. SE of Nashville and a lot of things aren't available around here, I will try Purple Power next warm day. I've got a couple of gallons of Purple Power, and I 'was gonna' try that next anyway. Spencer, I will supplement the Purple Power with brake clean on the real nasty areas. Cimmer....Extreme Greem Automotive Cleaner-Degreaser looks real good also, but buying it is the problem. It shows ONLINE that you can buy it from Stearns (the manufacturer I think) or at Fleet and Farm stores. In Illinois and Wisconsin they have Farm and Fleet, but Fleet and Farm is a different chain. Our Grandson lives in St. Cloud MN., and there is a store there. The next time we get up to visit him again, I'll stop and pick up a jug there. Thanks
  15. My 89 Royale has had a messy oil leak for longer than I'll admit, and I think I have at least one source fixed (the ignition sensing coil lead gromet). Yesterday it was 72 degrees here (central TN) and I decided that I'd work on cleaning up the greasy mess my engine had become. I had two spray cans of different engine degreasers, but really they didn't do a very good job. Yes, I did get quite a bit cleaned up, but there's still a lot left even though I brushed anyplace I could get to. I did some online research and there a lot of different cleaners that people claim work great, including Gunk foam (not what I used) and Purple Power. There were even some home brew concoctions that used kerosene and other things. What do you find that works for degreasing a motorcycle engine?
  16. Yes, the shift lever behind the cover should be up. If you look at the shift shaft after you get the cover back on and the C clip back on the shaft, look at the end of the shaft. You will see a line pointing at about 11:00. Put the shift lever back on the shaft so that the line is in the center of the gap in the shift lever. This is how you can get the lever back on the shaft in the correct position.
  17. It's behind the nut. The hole in the nut is not big enough for the rod to fit through.
  18. My 89 has it and I believe that after the second update on the 83's they all were the same.
  19. Thanks! Saddlebum--The steel ball in the piece of vacuum hose is great. I did something similar, but I need another one and I'm not sure what I used is sealing 100% Cimmer--After I looked up the plugs you used, I did a search for the part number they listed and found lots of places that had them. On E-bay a set of 4 was listed for $5.00 with free shipping. The bad thing is they're coming from Taiwan but I'm OK with the delay for shipping. Thanks again....
  20. What have you replaced the vacuum plugs that you remove to sync. you carbs? I've bought some at the auto parts store, but they don't hold up to the heat for very long. I've made some with vacuum hose with the end plugged, but I see that I need to improve them because the plug I used seems to leak a tiny bit. What have you used?
  21. Yes, the regulator SHOULD have metal behind it for a heat sink, but mine is burried in the bottom of the right fairing cover, and is mounted to the plastic. With my bike running for about 5 minutes including some time at 3000 RPM, I took my heat gun and measured the regulator's temperture.....it was about 90 degrees F. After my bike had been running for about a half hour and the cooling fan had come on and turned off several times blowing hot air back, the regulator only measured 114 degrees. It was 60 degrees in my work shop.
  22. Jean and Earl, May our Lord help you both get through this.
  23. The MOSFET regulator will NOT fit in the original regulators position. What I did was: 1) I mounted the MOSFET regulator on the inside of the right fairing upper. It's been a couple of years, but I think I probably removed the right fairing half to do this. After I did it, I thought about putting a piece of metal behind it to act as a heat sink, but I never did that and things are holding up fine. The first picture (7213) shows where my regulator is mounted. The bottom of the picture is the inner side of the fairing, and you can just barely see the fins of the regulator. There isn't a lot of extra room, but it does fit here. 2) I extended the 3 stator leads with #10 Gauge stranded wire so that they would reach the regulator. I ran the new leads up the left frame, across the top of the frame, and into the fairing. Picture 7215 shows the white wire is used going between the back of the air filter and the gas filler neck, and then into the top of the fairing. The top of my fairing is cracked, so you see pretty good here. 3) You have to connect the black lead from the regulator to a good ground, and I seem to remember there are several bolts that hold the inner panel of the fairing onto the frame that are good for this. Then I connected the Red regulator lead (using #10 gauge stranded wire) to the main 40 A. fuse. You do NOT want the battery side, but the other side of this fuse. Picture 7214 shows how mine is connected, but I've replace my OEM main fuse. If yours is still original, it will be to the left of the battery. Skydoc did his 86-93 also, but he put it underneath the trunk. Even though mine was a 89, I decided to go with the fairing mount. On a 83-84 you don't have that choice, and probably not on a 85 either.
