1st Gen Fork Brace
Bob Myers replied to 84xj1100's topic in Venture and Venture Royale Tech Talk ('83 - '93)
The stock brace is pretty thin and slightly effective. The guy who works for us can actually take one of those and flex it with his bare hands, I have seen him do it several times for people who did not believe. With that in mind know that the Venture in full trim weighs in excess of 750 pounds and roughly 50% of this is supported by the fork tubes coming down on an angle. If you sit on your bike with full weight on the wheels/tires and shake the handle bars back and forth you will see the whole fork assembly shake and wiggle. A heavier brace will stop a huge part of the oscillations you feel when this happens on the road. Someone earlier described the forks as "spaghetti like" and that is as true a statement as I ever heard. You have several options for a newer heavier brace, Condor has some he is selling, my machine shop also makes and sells them, check the classifieds or check with Condor. -
Bike only on mine too

those people are paid avertisers on http://www.venturers.org, are you a member there too? If so, that is where it is coming from.

I can make you a set easily, but as I said earlier, I'm not happy with the part about it being raised up 3/4 inch when you move it back http://i75.photobucket.com/albums/i301/Bob_Myers/P1010146.jpg

He is "entertaining" offers right now. Mileage on this baby is still under 1,500 !! Mileage right now is 1, 616 miles. Still a little cold natured, but smooth as can be once warmed up. If 70 or so of you fine folks would "loan" me $100.00 I could belong to this, bringing my fleet to 5 bikes. I promise I'll eventually pay you back.

Rode it today, man what a sweet ride when it runs right! Sure wish i had the coin to buy it. I'd have to sell everything toafford this. [ame=http://s75.photobucket.com/albums/i301/Bob_Myers/?action=view¤t=Jun042008-VID00008_1.flv]Jun042008-VID00008_1.flv video by Bob_Myers - Photobucket[/ame]

Update for you 50 some who read this and had no WAG as to where to go next. I pulled the carbs again, I'm getting really good at this. 15 minutes on a cold engine I can have the set lying on the bench, on this bike any way. I pulled the bowl off of the 2 right carbs since they were the ones that were lagging, using a hypo and needle for insulin shots I squirted carb cleaner( the soaker stuff not aerosol can stuff) into the passages I could not determine clearness of. Let that sit while cleaning the idle jets for the umpteenth time. One of them was clogged somewhat and after prodding with a strand of stainless wire from a electrical doodad I finally got the glob out. back to the passages where I forced cleaner in and hit them with air pressure, one was already open, the other came undone soon after. reassemble the carbs, using a 1mm gage pin I set the other three to the master carb and proceeded to pull the plugs on mixture screws, checking the screws I found that one of the screws, and it was on the offending carb was screwed all the way down to seat, the other right carb was 1 turn out. The left side has always warmed right up and the screws there were out 1½ turns.Feeling really good about the find on mixture screws I put the carbs back on. I bench set the screws at 2½ turns out. I hooked up my mercury manometer and lit a fire in the engine. Once it came to life and got over the dry fuel bowls it sounded really good. Actually the best I have ever heard it sound. Let it warm up and cranked the idle way up, let it settle down and begin to smooth out even more. When it settled the merc manometer showed my left side front/rear almost perfect, and right side fron/rear about 5mm off. Brought those to even, then evened up the left/right. By bench setting with gage it was less than 2mm off balance. Shut it down removed the manometer and replugged the carb bases, cranked the idle down and fired it up. It really sounds strong now. Can't wait for the danged rain to stop so I can ride it, once it is purring it goes up for sale. Should move quickly, a 99rs td with only 1500 miles on it!

So is the limit on the overbuilt U-Haul trailers. Means nothing except liability release

I'm calling on the carb guru to help with this 99RS. It sat for 9 years, first 4 the owner would start it up and let it run until the fan came on. Last 5 years never started.Bike has less than 1500 miles on it! I pulled the carbs, opened the bowls and found lots of pretty brown varnish. Pulled all the jets and soaked in carb cleaner, blew them out with compressed air( hold on to the little ones, they are hard to find when you send them into air driven orbit) and visually looked into them to ascertain they were clear. reassemble carbs. Use round gage pin to bench set the sync, had them within about .1mm of each other for butterfly opening, each one qualified to the master carb with idle screw. Installed carbs and finally got it to fire and run. Left side heated almost immediately, right side did not. Put my mercury manometer on, right side was a bit higher on vacuum than left. Adjusted all 3 screws in proper order at about 1000rpms, blip throttle and let it settle and they returned to level setting(within.5mm from lowest to highest). Reassembled bike, test ride showed cylinders were lagging, pulled plugs, right side is lean. Fast forward to 4th time carbs come off, I checked sync again, looked good on gauges, rides rough, winshield shake and such. I just blindly reached in and "tweaked" the front screw on right side, rode it again. A little less vibration. Fast forward, 10 or 12 stops and it runs pretty smooth just blindly tweaking the 3 screws. Put the mercury vacuum gauge on again and right side is low on vacuum. But it is smooth after you get off idle. When starting cold it only runs on left side for a couple minutes then right side starts to show heat on the pipes. First 2 minutes you can hold the pipes and no heat, left side will burn you in the first 20 seconds. If you mist ether or gasoline into the right side intake it picks it up and idles up. My feeling is idle circuit is still plugged with gunk and varnish.Other than the brass jets what can be clogged?

There was no previous guy. The bike is basically a brand new 99 model, with only 1500 miles on it! i rode the bike about 5 miles 8 years ago and it wasn't "exactly right" then, and then it sat for 8 years in a heated garage without being started. I pulled the carbs, soaked and cleaned varnish and dried gunk out of them. When i reassembled the pack of 4 I did just what you describe, sort of. I used a round gage and set the butterflies at .090" with the carb that has idle screw as master. When I fired it up it would run good on left bank, but no heat on the right, vacuum gage was wthin 1.5mm from low to high,if you revved it up a bit it would smooth out somewhat and start heating right cylinders. I surmised from that there was still gunk in the idle circuit. I pulled the carbs again, and soaked the carbs again for the right side. repeat with .090" gage for bench set on butterflies and install. No difference. I ran a couple cans of seafoam through the tank and it is getting better. Weird part is where I did what I described as just randomly turning the sync screws, and it getting smoother. Yes, Iknow it aint supposed to work like that. To check my mercury gauge I fashioned a dual t fitting and pumped it down with a handheld vacuum pump. All 4 colums pulled up dead even as they should. With that I am reasonablt sure my gauge is not weirding me out.

On the second gen I have been working on I sync carbs with my mercury vacuum gauge. Idles fair, has no low end power. Once you get underway it picks up and runs better, with a definite vibration in the windshield/handlebars. After checking the sync 3 times and concluding it was as close as possible, .05mm difference in volume, I stuck a long phillips in the side bag and rode off. After riding about 5 miles I pulled into a drive and tweaked the left/right adjustment. Hmm, better off idle responce, better smoother acceleration, to off the side I went again. After I repeat this about 10 times, the bike idles smooth, pulls away on all 4 cylinders and has almost zero shake in the windshield/handlebars when you hammer it. Out of curiosity I put the merc gauge on it again. It was so far off it should not have even ran. 99rstd, 1,500 milles on the clock

87 VR rider's headset level adjustment
Bob Myers replied to Gearhead's topic in GPS, Audio, Electronics
Or you can buy tuner cleaner at radio shack, take the knob off and spray it very heavily into the hole, then replace the knob and run it through its range of motion several times. If that helps then do it again to get it all. Or you could take the box apart and get right to the pots. They're just dirty, they don't attenuate enough current to cause them to burn out. -
Wind Noise in Headsets from Microphone
Bob Myers replied to a topic in Royal Star and Royal Star Tour Deluxe Tech Talk
The tic-tic-tic noise is spark plug/plug wire noise. You either have a cracked plug wire or non-resistor plugs, or both -
I know, I know,,,,, but I aint tellin!

Thank you Joe for updating us, Tina and Ray and I were anxiously awaiting news. Speaking of Ray, without any prodding he told us that you guys welcomed him as if he were part of the Venture family. For this you have my sincere gratitude. I feel badly about inviting him along and then not being there to accept responsibility for all I promised. He is really impressed with the group, and now wishes he had a grown up Yamaha too:crackup:
-
Oh my, as a new friend of these folks I am very upset to hear this. Joe, when you read this please tell John I will say a prayer for he and Teresa. They are both super, super nice people.
-
I thoroughly enjoyed the fellowship with my new friends, and am terribly sorry about not being able to make Sundays ride as planned. I especially am upset about not being able to lead the group through Red River Gorge, but there was a death in the family that we learned of Friday night after returning from the M&E, and family matters take precedence. Tina and I look forward to seeing all again.

Oil that is dirty in appearance is only relative to how well it has been changed in the past. For sure fire knowledge on what the oil is really doing save about 3 or 4 ounces in a clean bottle of some sort and have it analyzed. We used to do samples on the trucks at 5k and would schedule changes according to results.

backfiring into airbox is a sure sign of lean condition. Are your slides free, diaphragms solid?
-
Tim, The circuit you describe sounds far more simple than where I am. How/where do you signal the mute pin with the 6 volt signal? Is your audio from ham unit clunking a relay in addition to feeding signal or did you go on the board and tap the AGC circuit? Where would I pick up the rear mic cable in the fairing? Does this also allow you to feed audio back to the radio to tx? I'm using an Ht that when keying sends audio through the outer ring via taking center to ground. Typical of Kenwood and Alinco. More info please!
