Ever since purchasing this 86 VR in April, I have been chasing an acceleration hesitation problem. Only hesitates when engine is at idle and the throttle is cracked open. The motor does not respond and hesitates and may even die. I have been completely through the carbs, including new sliders and diaphragms. No vacuum leaks at alll anymore. Is this a symptom of running too lean or too rich? Everything else is fine, compression is great, plugs are new, well fairly new, new wires, boost sensor is operational, no problems with the vacuum line to the boost sensor. Valve adjustment is right on. What am I missing? I think is still a carburetion issue but can't pin it down. Any thoughts? -
I am checking to see if there would be enough interest from members to make it feasible for me to buy about 10 (or more) of the Ignitech TCIP4 V80 TCI ignition modules. These units would be a 30 minute or less job to install & be riding with. I would get these units from Ignitech, pre-load a Venture program setup with mileage and performance balanced. The adapter harness would include the wiring for the pressure sensor that the TCI uses. The stock Venture boost sensor is not compatible with the Ignitech unit & can't be used. I would supply either a brand new boost sensor or one from a auto recycler, the second option being much more economical & would be fully tested by me. I will be able to supply unit in either 83-89, 4 pickup coils or 90-93, 1 pickup coil versions . Ignitech Site link: http://www.ignitech.cz/english/aindex.htm I can get these units and resell them with a gently used boost sensor, fully tested and ready to go for $225 US plus shipping. If a new boost sensor is wanted the cost would increase by about $50 (subject to change). I would need a partial prepayment in order to finance this. Balance of payment due when ready to ship by me. Turn around time would be about 2 weeks. It would take me about a week to get TCI's and some time to wire & test them. And being upfront about it, this is about $25 less than the unit can be purchased from Ignitech and the cost of a used boost sensor factored in. All that would be needed by user to utilize this unit would be to unplug the 2 cables from the existing TCI & plug them into the adapter harness. Then mount the TCI, which is slightly larger than a pack of smokes & mount the boost sensor. Connect the hose from the #2 intake boot to the boost sensor. Mounting of TCI can be on air box lid or left radio pocket. The TCI can be hooked up to a laptop that either has a com port or one with a USB port & an adapter that will be made available. It will not be necessary to have a laptop hookup if you do not desire to modify the program I would load in it. With the use of a laptop connection, the user can customize settings as desired. The Ignitech thread is located at link below, there is a lot of info in it. I will supply an electronic manual with the TCI. I will also put on the CD any useful info I have collected while using this unit. Each CD will have additional info such as bike wiring schematics and other items not supplied by Ignitech. The Ignitech manual, TCIP4 program and initial module program will also be included. http://www.venturerider.org/forum/showthread.php?t=40414 1st picture shows the TCI, wiring harness, a used pressure sensor and the software CD. Also are extra pins Ignitech supplies if user wants to add other non-utilized features of TCI, such as fuel pump relay control, shift light, inputs for shut off features. 2nd picture shows an boost sensor. 3rd picture shows end view of TCI 4th picture shows adapter harness with boost sensor leads. 5th picture shows Miscellaneous settings screen 6th picture shows Bike settings screen 7th picture shows 2D advance map example, would be different in supplied format. 8th picture shows 3D advance map example, would be different in supplied format.

After that heartbreakin' video prior to this, I felt we needed a boost. Bet you smile at the end of this one. http://wimp.com/millionwinner/

The #2 carb on the 85 engine has a hose hookup that appears to be about the same location as the 83 port for the boost sensor that runs to an emission system. Since the good spare TCI I have is for an 83, I wonder if that hook up would work correctly. I also wonder if all these emission hoses can be removed and blocked. Randy -
My MP3 player just does not have enough volume, I was thinking about building an amp to boost the volume or buying a pre-made one and putting it inline in the fairing. Has anyone else done anything similar?

...but what exactly does the "boost sensor" do on a G1? "boost" brings to mind turbo systems.............

TCI location relocation
bald josh posted a topic in Venture and Venture Royale Tech Talk ('83 - '93)
Ive seen a few places where people have asked where to find the TCI and boost sensor. This is how i got to mine and relocated it without pulling the air box, etc. from the right side with the chrome cover pulled off you can look up into the cavity and spot both, i was able to remove both TCI mounting screws from this spot (pulling out the black plastic/ rubber engine cover is a huge help. I used a small socket wrench with phillips head to gain the clearance. the boost sensor is accessible from here as well. I no longer have the tape deck installed in my 87 so thought i would relocate the TCI in the empty spot of the fairing. I pulled the left side of the fairing off, drilled a large enough hole in the inner panel and passed the wires through. put it all back together and velcroed the box in place.I have the cover that closes up the hole where the tape deck is from so its all sealed up and tidy looking.Seems like alot of you like your radios and im not sure it would all fit with my radio still there, but i thought i would share. #1 boost sensor harness #2 boost sensor vacuum line #3 TCI #4 front of air box if nothing else i hope this helps someone locate these if they are looking. -
Ever see something like this before? Does it actually work or is it more gimmick than anything else? http://cgi.ebay.com/ebaymotors/TUNING-Yamaha-Royal-Star-V-Max-Suzuki-Hayabusa-Intruder_W0QQitemZ140339503929QQcmdZViewItemQQptZMotorcycles_Parts_Accessories?hash=item20ace2e339&_trksid=p4506.c0.m245

Just recently my 86 VR has taken ill. She was running real well and strong until just last week. All of a sudden she seems to be lacking in power throughout the rpm range. I have synced the carbs and they are right on. Suspecting that the boost sensor may have crapped out, I checked the vacuum at #2 and it is good and when reconnecting the vacuum hose to the boost sensor, the rpms pick up. That, as far as I know is a sign the sensor is working and advancing the timing. New plugs installed not too long ago and appear to burning well. New wires and caps as well. Just last night, I pulled the air box top and filter and started the motor. Number two slider (the carb/cylinder providing vacuum to the boost sensor) is not bouncing/moving at all. I will have to pull that carb cover to check out what may be going on or what isn't going on and hopefully I can resolve the problem; quickly. What would be the symptom of one slide not working? I checked out the diaphragms not too long ago and all checked out; no holes, old but no holes. Perhaps the vacuum port that directs vacuum to this slider has somehow gotten clogged or something. Nbr 2 is firing because the pipe gets hot immediately after starting cold. If I can't figure this out quickly, I will still be at the rally; however, I will be on my Ultra. Any ideas or advice about a faulty slide.... I am all ears.

I finished a tear down to frame motor, wiring and reassembly of an 87 VR I bought on ebay. The bike is on the road, looks and rides great :12101:but........ I was floored by the poor fuel milage. When I reassembled the bike I replaced the boost sensor as it was fubar. I found somewhere along the line a line restrictor was put on the vac line to the sensor.I put it back in at the same time as the swap. Had never seen one on other VRs though. Fuel mileage was about 20 mpg:confused07:. Thinking about the work done, couldn't find an issue. Pulled off the line restrictor and now am about 43mpg with better power curve. Why the radical change in mileage and performance with it out ? Can't find restrictor in any parts listings so, for now it's in the box of parts I don't figure need to be there:soapbox: -
Been struggling with a no spark condition the last couple of weeks. Bought a TCI off of eBay, didn't fix the problem. I initially had spark on all but cylinder #4, then while working in the area, wrestling the battery around, and swapping the TCIs, nothing. Pulled the ignition and pickup plugs, all resistance reads as it should (114-119 on pickup coils, 3.2-3.5 on ignition coils). The TCI is getting power, bike is in neutral and the kickstand is up. As I was getting ready to unleash some words no child should hear, I decided to check the boost sensor. When getting no reading between the + and - terminals on the TCI, I tracked back to the sensor itself. During my mangling process, the cover of the sensor was broken - enough that there is a hole in the top. I know the boost sensor helps adjust timing, if the circuit is damaged can it shut off spark entirely? If so, any way to fool the TCI into running - even poorly - long enough to shake out any other gremlins?

What does the boost sensor do on a 1st Generation? Ronnie

OK, So I have removed my YCIS and plugged the ports, but what exactly does the sensor do that is has a vac line coming off of #1 (#2?) jug and runs up under the dash and hooks to the Pressure Sensor / Free Boost Sensor? I can't seem to find anything about it. Just wonder ing, and how does one test it? -
I think I've seen mention of a restrictor in the vacuum line to the boost sensor, does anyone know for sure if there is one and where is it located ?
