Is that your actual plate number, or did you Photoshop it? Would be a hard one to forget. Gary

Joe, I would encourage you to mount the TCI on top of the air cover while you have it out. You already have the one tab cut off that you need to do to mount it on the airbox anyways. You need to do this in order to get the tank cover to seat properly. Cut tab goes towards battery. It gets it away from the heat of the cylinder head, as well as in a dry location. You do not have to cut any wires to do this. Just reroute them. Looks like you caught the diodes just in time. That was a good solution to open up the box as well. I had difficulty with lifting traces when I unsoldered the board from the box, what you did looks nice. Gary

Way !! The rear tab is intact, grommet & bushing are present and accounted for. Gary

The gasket is in place and seems pliable yet. Gary

Does anyone have a suggestion for making the tank cover not pop out of the front holder on a 1st gen? This has happened a few times and it is a little distracting when it does this. It only does it around 90+ mph. I will help those that have the obvious answer, stay within the speed limit. I know that one, but it cuts into the fun factor. Gary

Attached below is a picture of a set of carbs. Just above the crossbar that the two black hoses are sticking out of there is a hole on the right carb. On the left carb there is a plug in this hole. I believe yours will have a brass plug in the hole. Don't drill very big, or deep. Hole size is just under 1/4" in the carb body. Mixture screw head is about 1" inset Drill a hole large enough to get a wood screw started in. You can the grip the screw and work the plug out. You do not have to plug holes when you are done adjusting. Gary

Early 83's do not have a reserve setting on the petcock. If it does have a reserve setting, I think they put a notch in the right side cover so you can reach it without pulling cover off. This started towards the end of the 83 run and continued on. Gary

Appreciate it Squueze, but this subject is certainly going to be efforts from multiple people. Fairly complex to get right. Especially since some of us want different end results. I for one want power, others will look more towards fuel economy. Gary

Mohican State park is a great place to ride. I live about 20 minutes from there and like to go riding around there. Especially the two roads that lead down to the covered bridge. Gary

Below is a chart from the 86-93 service manual showing normal fuel pump operation. Also shown is fuel pump relay testing cut from manual. 83-85 bikes are essentially the same, but the 83-85 manual does not have a as good of a write up. The fuel pump will be powered up when you turn the key on. In about 5 seconds, if the engine is not running it will shut back down. What this means is you need to have a meter connected, so that when you can see it, then turn the key on and see if the unit gets power for 5 seconds. There is some electronic circuitry inside of the fuel pump relay that contains a timing circuit. It senses the firing of the #2 cylinder and keeps the relay energized when the bike is running. It shuts the pump down if bike is not running and key is on. The 83-85 is essentially the same as the 86-93 setup but they have a separate control module for the fuel pump relay.

A small addition here, do not remove this panel with a full tank of gas, it needs to be below 1/2 tank full. Fuel will run out of panel when it is loosened if tank is full. Gary

Here is a picture of what you need to do to stop CMU warnings. I believe Saltydog made this up. The reed switch contacts on the high & low beam circuits need a jumper soldered across them on the non-component side of the board. Please note that this info pertains to a non-royale style of CMU. Gary

Looks like it might be a Vmax to me. You can see where the shock bolt was cut off and ground down in right of picture. Gary

You can use a TCI from 84 through 89. The attached picture shows a red arrow pointing to one of 8 diodes. They are all the same and lie in approximately a line straight up. A 1N4001 or higher diode can be used. Gary

Here is some info on what I have done so far with the module. I had a phone conversation with TVKing63 and some PM's back and for with Squeeze, both have helped me get to this point. One of the problems that I was having is the output voltage of the GM map sensor that I am using is just a little over 3.0vdc at idle. The Ingitech software has a high end hard coded threshold of 2.5 volts at idle. With some trial and error, I found that if a 250K ohm resistor is put in series between the output of the map sensor and the input of the Ignitech unit, the idle voltage will be approximately 2.0vdc. By doing this the full range on the Ingitech mapping curve can be utilized. Prior to putting the resistor in, I was unable to use anything below about 30% vacuum advance. Now I am able to start at the 0% bracket. The next issue I was seeing, and it may not be a major one, was the pulsing of the vacuum curve at idle. TVKing63 indicated he was seeing the same thing but he thought it smoothed out alright above idle. The solution that I came up with incorporates two ideas from previous posts in this thread, with a third added. Somewhere, and I can't find it, someone had mentioned tying all 4 vacuum ports together to smooth the curve. This is the first thing I did. Second was to get the inline restrictor that TimGray had used. The third thing was to add a small canister to the vacuum line going to the map sensor. I used a piece of 2" PVC, just long enough to be glued in place between two PVC caps. In one of the caps, I epoxied in two 3/16" plastic air nipples. There is an upside and a downside to the canister idea. The upside is that it will smooth out the pulsing. The downside is that it will induce a lag into the throttle response curve. The reason that the canister so short is to reduce this throttle lag. A smaller diameter canister may still work, but this was the path I was on. Squeeze suggested I use an RC timing circuit, which consists of a resistor and capacitor in parallel, to smooth out the pulsing. This would be a more compact solution, but for now I am satisfied with the canister. There are two videos that I put on You tube next that show the difference without & with this canister. First one is without the canister, notice the blue bar, which displays the TPS (Map sensor) voltage. It is varying quite a bit. Both of the video's were taken with the TPS threshold set lower than optimal, so the bouncing would be evident. [ame=http://www.youtube.com/watch?v=wqhoGqGE4_A]YouTube- ‪TP wo can‬‎[/ame] Second one is with the canister inserted in the line. Now the TPS voltage is much more constant. [ame=http://www.youtube.com/watch?v=ghQNJn23sAo]YouTube- ‪TP w can‬‎[/ame] Next video shows screen views with the engine being reved to display TPS response. I believe I will lower the upper threshold of the TPS voltage from what is shown in this clip. [ame=http://www.youtube.com/watch?v=u3K3CKEMxvA]YouTube- ‪Map w can ‬‎[/ame] Picture next is of the canister. [ATTACH]48709[/ATTACH] Next is one of the fitting I found at O'Rielys that I tied the four vacuum ports together with. Part number is Dorman 47361 [ATTACH]48710[/ATTACH] Next is one of four vacuum ports tied together. [ATTACH]48711[/ATTACH] Next is of all three components to Ingitech system I am using. [ATTACH]48716[/ATTACH] Lastly is the software curve I am using. I downloaded and tried TVKing63 latest map 'Venture 11e 2500-4500TPSV.ign' This one seemed to be lacking some throttle response. From what I have researched, it seems that full vacuum advance is not useful at WOT. This is based on article referenced next. This is of course just one opinion on the matter. http://www.thesavoy.de/html/vacuum_advance.html Squeeze sent me what he thought would be a good starting point for a map. I tried it as he suggested, but there was a distinct hesitation when going from a steady 4500-5500 RPM to WOT. I modified his curve by pushing the advance out farther and this cleared up the hesitation. Below is a screen shot of TVKing63 3D curve and Map. [ATTACH]48712[/ATTACH] [ATTACH]48713[/ATTACH] Below is shot of what I am trying for now. [ATTACH]48714[/ATTACH] [ATTACH]48715[/ATTACH] Which style of mapping is better can be best measured by a dyno, which I hope to do this fall. The previous one I did was a low cost one at a shootout. I did not get torque values or A/F readings which will be very useful to guide me in what to do to get some decent HP out of this bike. Gary

That fairly closely matches up with the 84 parts fiche. Depends what year he had. If you don,t have one, PM me your email address and I will send it to you. Gary

No, I have not completely interchanged dashes. On my 83, when I put the 88 wiring harness in, I used an 88 dash. I did swap out the speedometer head & tach in order to maintain the correct mileage on the bike. I did the tach due to the markings on the face are different from MKI to MKII's. But I did use the 88 CMU. I have had an 84 wiring harness, which did have the correct CMU connectors for the Royale dash. This is what leads me to believe that the CMU units from an MKI are the same as an MKII. I looked in the parts fiche and it only lists part numbers for the Royale dash, I do not see listings for the standard dash in order to compare to an MKI. I specifically looked in the 88/89 version as I am almost certain was offered with the standard or Royale dashes. I do not see in the fiches where a standard part can be ordered in lieu of an upgraded part. I am almost certain that there were MKII's in 88 & 89 that had the standard dash in them. This was the model XVZ13D. The XVZ13DU had the Royale dashes in them. I am not aware of any 83 dashes that were the Royale version. 84 & 85 models were XVZ12L, standard dash and the XVZ12DL which had the Royale dash. 86 & 87 only show the Royale model XVZ13DS, which all had the Royale dashes. 90-93 models were only the Royale version, model XVZ13DA. All of the above models are a result of what I learned when I did the wiring schematics, which may be wrong. I did do a version of the schematic for an 83 showing a Royale dash, which I now know was not a stock production model. At the time , I thought the XVZ12DTK model had the Royale dash. The XVZ12K was the stock model. Due to finding the wiring connector difference I noted in a previous post, you are correct saying that an MKI Royale dash will not be plug-n-play in an MKII bike. It would at a minimum,require swapping out the wires in the plastic connector on the MKI dash head to the one in the old MKII dash head. You are also correct that there are many more MKII dashes available, might as well get the one that will fit right in. Gary

I do see the difference in the wiring now. Due to the cruise light there is a six pin connector (5 used) to the cluster lights on the MKI's On the MKII's this is a 4 pin connector, since the cruise light was omitted. My bad. Gary

First picture is an 83 dash. Below is a picture of an 89 standard model cluster. XVZ13U model. The XVZ13DU had the upgraded royale cluster. There are different markings on the face of the tach and speedo on the MKII's, also the MKI's had the cruise light in the face of the tach. That may be the only difference. Gary http://i1007.photobucket.com/albums/af193/gdingy101/120509024.jpg

Do you know what is different. From the wiring diagrams, they look the same. Below is a picture of a Royale cluster from the 83-85 service manual (supplement). Top caption says XVZ12DL. Gary http://i1007.photobucket.com/albums/af193/gdingy101/MKIroyalecluster.jpg

Edit to this post. Due to a wiring connector change the MKI dash does differ slightly from an MKII dash. See post farher down for better description. Gary An MKI from a Royale should work if the existing unit is a Royale. I don't think there are any differences. The non Royale units have totally different cable connectors. It is a Royale dash if it has the clock/timer display at the bottom. First picture below is a standard unit. Second picture is rear of standard unit. Third picture below is a Royale unit. Fourth picture is rear of Royale unit. Gary

Bleed it again, I like the synthetic brake fluid DOT 3 or 4. It is not nearly as harmful to paint as regular fluid, and it is less disposed to absorbing water. After you have it bleed, take a zip tie and tie the clutch lever back all the way back against the grip. Loosen the cap and rubber so air can get in to the master. Leave it this way over night. You may need to do this a couple of days. Don't ask me how this works, I just know from experience that it does. Gary

That would seem to indicate you have plugged idle circuits in the two carbs. Seafoam it very heavy, like a half can in a tank that is less than half full. Ride it hard for an hour, then let it set for a day or so. Run the rest of the tank out. Fill it with 89 or better about half full and put the rest of the seafoam in and ride it hard some more. You can get seafoam at wal-mart and autozone for sure. It's about $9 for a 16 oz can. Gary

Try sucking on the hose that goes to the vacuum sensor. Seriously. If you can draw air through it, then it has gone bad. I have one that did this. I don't know why that would cause cylinder not to fire, but it is something to check. Gary

I am having a slight drip out of the left side on mine also. Sealing washer on bottom of middle drive cover was dry. Drip is forming on floor an inch or so ahead of bottom bolt on middle drive cover. I thought I might have a leaking side cover gasket, so I got new ones for stator and mid drive cover. When I pulled covers off, it was dry as a bone in behind middle drive cover. No leaks around gear indicator, shift shaft or stator & pickup wires. Cleaned surfaces, no cracks or nicks found. Coated both sides of gasket with sealer, which I will regret next time I need to pull them, and replaced covers. I still have the drip. Next culprit may be a leak in the oil pan. Or possibly a loose case fastener. Doesn't always drip just once in a while. Enough to be a source of irritation due to the ribbing from my Harley friends. This coincidentally started around the time when I put the Harley drivers backrest on the bike. Might be a virus. Gary
