Starting Problems
dingy replied to uthpda's topic in Venture and Venture Royale Tech Talk ('83 - '93)
Look at post #31 and open up the second PDF, 84-85 Yamaha Venture Starting Circuit. The problem would seem to be that if you can get bike to run by jumping the L/W wire to ground that the start switch is not closing and completing the circuit to ground and picking the start relay up. You are only bypassing one component and its associated wiring by jumping L/W wire to ground. This narrows problem down to that one component (start switch). Look at the middle schematic, this one is configured for key on, transmission in neutral. Clip the Positive lead of the voltmeter to the positive battery terminal. Unhook the Blue/White (L/W) wire at the solenoid. Hook the negative lead of the voltmeter to the wire harness side of the connection. Press the start switch, you should see 12v (about) on voltmeter. If this is good, then the start switch is functioning well enough to pass the voltage reading through. There could still be an issue at start switch that is is corroded enough to not allow enough current to pass to pick the start relay. Here is a link to how to clean the starter switch the better way. An alternative is to shoot spray cleaner in it and maybe it will start working. http://www.venturerider.org/forum/showthread.php?t=43027 Gary -
Dim Headlight
dingy replied to Dr. Psycho's topic in Venture and Venture Royale Tech Talk ('83 - '93)
http://www.venturerider.org/forum/showthread.php?t=58880 The head light indicator on the dash is triggered by a current sensing circuit on the CMU (dash indicators) circuit board. The current for the bulbs passes throug a coil of wire that triggers a reed switch if there is current within design specs. Considering you are able to wiggle wires and affect the symptoms, it would seem that problem is in vicinity of head light. Other area that would be suspect is the start switch. The three primary connectors I would check are the one going into head light socket (dudh). 2nd is the one going into the Reserve Lighting unit. This is a black rubber covered unit about 4" x 2" x 1" (roughly). Has about an 8 conductor connector going into it. I think it sets at the very top front of the head light pocket. 3rd would be the connector going into the CMU on the cluster head. Also involved as far as connectors go is the 6 conductor one that goes to the left handlebar controls & another 6 conductor one that goes to the right handlebar controls. Check all of these connectors and see if wires are corroded or dirt is in connector. Wiring diagrams are located at links below. This one is complete wiring schematic for 83 Venture, it shows all the connectors in place. This one is best to use for tracing wires out as how they are routed to various places on the bike. http://www.venturerider.org/wiring/83%20Yamaha%20Venture%20TK%20Wiring%20Diagram%20Rev%20C.pdf This one is simplified wiring schematic for 83 Venture, it shows same circuits as above schematic, but without the connectors, which simplifies the layout of the wiring and is easier to look at how circuits function. http://www.venturerider.org/wiring/83%20Yamaha%20Venture%20TK%20Simplified%20Circuit%20Diagram%20Rev%20C.pdf Gary- 3 replies

Mounting a GPS and other stuff
dingy replied to Venturous Randy's topic in Venture and Venture Royale Tech Talk ('83 - '93)
What all did you do to the pocket cover you made from aluminum? Is it a flat piece or are edges formed? How thick of mateerial? Waht paint did you use? Gary -
I could set my fax to try & send him something perverse. It may not go through but it would be worth the try. Gary

What is the rotor diameter on the front of a Yamaha 1997 YZF 750R? Bolt spacing between caliper bolts would also be helpful. I am looking at using a set of 6 pot calipers from this bike on the scooter. Gary

Can You Hear Me Now !!! How About Now !!! We just went to Verizon after getting fed up with Sprint's totally crappy reception. I even had one of their internet connection 'mini cell towers' in house and it still sucked. Got an Iphone 4s with Verizon. Fat fingers and touch screen keyboard are taking some getting use to. The voice commands with Siri are cool. Gary

I don't know of anyone doing a full crossbar, both technically difficult and unnecessary. If it is electronics mounts you want there are many different ideas that have been posted on here. Below are some pictures of what I did. The GPS is a plate welded to a stud. On the bar end I welded a nut to the nut that holds the upper bar on. Velcro on GPS holds it in place. Mount is rotatable to where it can be best viewed, then tighten up lock nut. The radar detector is mounted to a mirror stud that has had the middle bend cut out and welded back together. The ball swivel was mounted to a piece of sheet steel and velcro is used to hold detector in place. This same idea could be adapted to a camera. The line of site for the radar detector is outside of the windshield so it would be a nice line of site for a camera. Gary

New owner questions
dingy replied to Trevor Heath's topic in Venture and Venture Royale Tech Talk ('83 - '93)
I have the Bikini cut side covers on mine. They actually help cool the motor a little more in my opinion. I do feel a little more heat coming from the motor on my upper legs than before the side cover mod, but it is not real bad. It does give the bike a new look. I used a band saw with a fine tooth blade. You will probably need to touch up the cut lines so they are not obvious. The lower side cover strap needs to be reworked. I removed the braces that runs along the mid line of the motor from front to back and I haven't noticed any bad effects from it. I did put solid motor mounts in and an upgraded fork brace that probably compensated for the braces removal. I have functionally stress tested it a few times. The front knee plastic & cross bar in front of radiator were also eliminated. RandyA, Thom and a bike in California are the only ones I have seen with this done. I just followed in their footsteps with this change. If you do it, the motor is much more obvious. I went with flat black paint on the block & heads to try to make it look better than the aluminum. Few pictures attached. Gary -
My wife thought it was a christmas tree ornament. Thanks Don ! Gary

1991 Mk2 VR front rotor
dingy replied to Mike Mercury's topic in Venture and Venture Royale Tech Talk ('83 - '93)
85-89 Vmax front rotors are the same as the MKII front rotors as far as diameter. They have a different cutout pattern on the flat side, more like an MKI. Not sure about the width, but they are very close. Bolt pattern is the same. Gary -
Not at this time, but I think I will try to get another group buy together after the Holidays are over. Gary

RSV performance cam kit?
dingy replied to mike_waldman56's topic in Royal Star Venture Tech Talk ('99 - '13)
I would Venture to say the carbs/cams made 90% of the difference in this bike. Going from 28mm to 36mm carbs and getting some air into these motors is more beneficial than just about any other large scale mods. I think that he got much more than a 20hp increase. He has rear wheel HP as compared to the advertised crankshaft HP numbers. RWHP will be 15 to 20% lower than crank HP due to all losses are eliminated at crank. RWHP stock is probably in mid 80's. A decent header on the bike would probably yield around 10 more HP. The four individual pipes are the worst possible setup for power I have learned. They look nice and have a unique sound though.

I think you have about a snowballs chance in Hell of that working. Chance of either one of the rotor lobes and one of the 4 timing coils having the proper alignment to match what was done on the 90-93 are extremely slim. But then people play the lottery ever day with a million to one chance at hitting. Wiring harness would by far be the easiest part. Since there is zero adjustment in the timing at the pickup coils the lobe & coil would have to be perfect to match a stock TCI. The Ignitech unit would probably be doable as the timing is adjustable in the TCI via a computer hookup. It would be an interesting and probably frustrating project though. Gary

1991 Mk2 VR front rotor
dingy replied to Mike Mercury's topic in Venture and Venture Royale Tech Talk ('83 - '93)
Right & left MKII front rotors can be interchanged. There is a barley noticeable difference between them from what I and others have found. I have a front MKII rotor on the rear wheel of bike and it works fine back there also due to other slight modifications. Gary -
Replace rotor, stator cover, pick-up coils, TCI. Probably tweak the wiring harness a little. Gary

It don't take any real finess or skill to ride a bike and always take it to the dealer for what ails it. The 1st gen guys get thrown out of any Yamaha shop cause the bikes are older than the pimple faced mechanics they have. It takes someone with creativity and mechanical skill to keep something running that some of the parts haven't been avaliable for in this century. Kick our Maytags all you want, but they are the best handling, and without a doubt higher performing bikes than any Yamaha this site caters to. Gary
