    I don't think some people actually realize that all you are doing is measuring vacuum in the chamber between the throttle plate and the valves and comparing the vacuum from one carb to another or to three other carbs. This is because an engine on the intake side is nothing more than a big vacuum pump. By adjusting the amount the throttle plate is open, you are adjusting the amount of vacuum by adjusting the amount of leakage you are allowing around the throttle plate. Given this, if you have even a small vacuum leak, when you are balancing the carbs, you have to adjust for that leak. The more you open the throttle plates, the less that small vacuum leak will effect the amount of vacuum you are reading on your meter for that cylinder. With a small leak, you are having to close the throttle plate to bring that vacuum up to the point it matches the other carbs. As you open the throttle, that small leak will cause the levels on the meter to become uneven compared to the other carbs. If you have a larger leak, you can completely close that throttle plate and the meter may still show you that you do not have enough vacuum, making you think you need to close it even more. Another thing that can have an effect on vacuum reading is having an intake valve that has a small leak. At idle with very little air flow, a small leak can cause a small spit back of air that disrupts flow into the intake manifold and appear to decrease vacuum. As RPM"s increase, that small leak becomes less of a factor as the valves are opening and closing much quicker and there is more air flow going through the manifold which somewhat neutralizes that small spit back. The first thing you need to do is to try to identify any vacuum leaks. I usually spray some starter fluid around the manifolds under each carb and around the YICS system if you have it still hooked up, which I suggest you remove and plug. If you do not detect any leaks, you can adjust each carb to be more balanced in the RPM range that you normally operate, even though theoretically, you would have to be under a load to truly be balanced.

    It's got to be true, it is on the internet!!! RandyA

    Andy, I am afraid you may not have fixed the problem, you just fixed the symptom. If you had gas that was leaking from the carb and down the outside of the boot and then you tightened the clamp, the gas is now leaking down the inside of the boot and into the engine. This is not good either. You did good in isolating the leak to a particular carb, but you may still need to figure out where the gas is leaking from on that carb. RandyA

    And it really flows free if you do not release ALL the air pressure on the forks. RandyA

    Ditto on the Scotch tape. It is thinner than electrical tape and seems to be tough enough that the seal does not tear it. RandyA

    My girfriend has a Garmin, I believe, and it retains the top speed. I borrowed it for a couple of days to see if I wanted a GPS on my bike and I believe the top speed indicated when I gave it back to her was 94 mph. Condor, he is asking about the indicated memory that the GPS retains. RandyA

    I dozed off about 10 laps before the finish. RandyA

    Andy, after doing the needle/washer adjustment and new diaphragms on my 83, I have got as good as 49 mpg when running 2-up and running in the 50 mph range. Also, this has been with no loss of power. RandyA

    Very interesting pictures. There are probably few few of the people in these pictures still alive. RandyA

    We also have a lot of trees budding out. Got a while before winter is over. Biggest snow I ever remember here was in March 93. RandyA

    Poor old Danica has had a rough week in Daytona. She sure has a lot of torn up cars. RandyA

    Yep Lew, old farts and babies both tend to look a lot alike sometimes. RandyA

    Hey Dan, is there any prize for being the 500th poster on this thread? RandyA

    In 1977, while in college, I went to work for a camera repair shop/photography studio and that was my first time being around quality cameras. I ultimately ended up with a Canon AE1 with a bunch of lenses that is now in the basement in the bag. I now have a digital Nikon L110 that is a nice camera, but I feel I have very little control with so many of the things like light control, depth of field, exposure length and other things that made those real special pictures. I know there are digital cameras that address these issues better than mine, but I do miss using my old film camers. RandyA

    Heck, I probably still have scars on the back of my ankle from my 125 Ducati kicking back on me and hitting the passenger foot peg. Thanks Mark for bringing back some very old memories. RandyA

    Lew, just remember, what Capt Whitlock and all the rest of us have served for, is Liberty. The only way that I can deal with the idiots from Westboro is to accept that with true Liberty, there will be those that use it wrongly for their own agenda. The only reason that this scum is doing this is because this has been the best way for them to get attention for them to get more money from their scum supporters. Yes, in my mind it is absolutely wrong to abuse these freedoms as they have, when they are simply too stupid to know that if it were not for the Capt Whitlocks of this country that gave some or gave all, they would not be able to do this. Last summer, we lost a local soldier and the Westboro group were supposed to be here. With the crazy bunch we have around here, The Westboro scum may have not made it back home alive. They did not show up. RandyA

    Dingy, unless I am reading something wrong, my memory tells me that the RSV transmission ratio is slightly lower than the RSTD, especially in 4th and 5th. I do believe that when I was putting together the 2nd gen trans setup for the 1200 engine I have, I double checked the number of teeth on the gearset I bought to make sure it was an RSV version and with the data I had, and it was. I specifically wanted the RSV set because 4th and 5th was not as high geared as the RSTD. Somewhere I have the numbers on each, but at the moment I can not find them. But, my memory is telling me that on the second page (range) of this data that the RSV and RSTD data is backwards. RandyA I just looked at our Venture history and it shows the RSTD to have the .750 5th gear which is what this data is showing the RSV to be. It is my understanding that one of the changes to improve power on the RSV was to lower the ratios, as on the RSTD, 5th gear is only good at higher speeds as it is geared so high.

    To be sensitive enough to work while down shifting, it would probably stay on a lot when going down a grade, even if brakes were not used to maintain the speed you want. The only way it would be effective is having an additional brake light that also came on when the brakes were used, like the third brake light in a car. I actually have a small LED brake light mounted on my trunk under the rack that comes on and oscillates from one side to the other. RandyA

    I may have one for an 86 if I can find it. It will be a day or so before I will be able to look. RandyA

    Andy, I tried to lie out of it but couldn't and as we have gotten older, I guess that was just as well. :whistling:Genetics can be pretty rough sometimes. RandyA

    I would take a picture, but my son, Lil Venturous, borrowed the set up to pull a transmission in his car and when he took the pieces off the board that the oil pan nested in, he lost one of them. I have not needed to use it again, so I have not made another one. As far as this area, I feel blessed as it is a beautiful area and it is wonderful for riding a motorcycle. We have roads like the "Tail of the Dragon" everywhere. RandyA

    I do have to say that I believe the best handling my bike has ever been was when I had the used Venom on the front and the new E-3 on the back. I believe it handled even a little better than when I replaced the front with an E-3. My bike just did not handle good at 70+ mph with the Venom on the back. RandyA

    OK Al, it's time you start getting your moneys worth on the $12 you spent on this web site. To think about spending $780 on getting the head bearings fixed just hurts to think about. I don't know how many miles your bike has on it, but for most of these bikes, the biggest problem with the head bearings is they need a good cleaning and regreasing. Yes, replacing the bearings and races is great and I hope that is what they did, but usually it is just dried grease that makes them feel notchy. I am fortunate that as a kid I was the neighborhood fix-it guy for myself and my friends. This has served me well in being able to maintain my 83 Venture that I have had 16 years and have put about 125,000 miles on since I have had it. If I encounter anything that I am not sure about, I start here with specific questions and to be honest with you, the LAST place I would consider is taking the bike to a dealer. Another thing I would do is start asking around about folks in your area that may be able to help you if you are not sure about doing things. But, at least let us help you if we can. RandyA
