I can definetly help you our with the intake and all of the parts that I have used/am using. What COPS are you using on your bike? That is one of the upgrades I am planning on doing to mine.

Yes I am planning on doing a dyno run video, but I've got a few upgrades performance wise that are getting ready to happen over the winter. I'm thinking that hoping to break into the 100-110 hp at the rear wheel but if it makes more than that I wouldn't complain.

Well I will first start off by saying that cv carbs are going to be "better mannered" at higher elevations just because they are designed to "keep things within spec" during altitude changes. That being said I have not had the pleasure of taking this bike on a ride at those elevations but i took my last bike, an 81 gl1100 with this carb setup and upgraded coils/exhaust, on a few trips through the Smokey Mountains and it performed well. I could tell that the bike was a hair less responsive at WOT and was a bit more cold blooded at those elevations but was fine during normal riding after it was warmed up. I would definetly try upgrade to the ignitch TCI and have it tuned properly before doing any extended rides at 9k elevation and I wouldn't ride the bike until it was warm to help reduce the possibility of the fuel gelling in the intake and fouling the plugs. I live in an area of 780ish' elevation and am getting beautiful results from this set up, but I do plan on upgrading the TCI and trying to find better could for the bike. If you are going to perform the swap please keep me informed on the results so if I ever run into this type of question or make a road trip to those elevations I will know what to expect.

I finally got time to do an update video on the single carb set up on my bike. I have done a few power comparisons to a family members 97 vmax with stage 1 jets and a full ufo exhaust and continuous vboost, a friends stock 03 mustang cobra and a random c7 corvette, all with positive results. My bike Vs the 97 vmax with upgrades - my bike was able to pull away from the vmax on a 20mph 2nd gear pull, I was able to accelerate smoother at lower speed without downshifting, a 3 gear pull from 40 to 70 on the highway was also faster on my bike than the vmax. My bike Vs a friends stock 03 cobra - I was mildly suprised when my bike pulled away from the cobra, mainly due to power to weight ratio, but the bike was able to pull away from the cobra on a 20 - 100 pull. The bike didn't "blow the doors off" the cobra but it was a consistently growing gap between us. My friend was a little upset that an old jap cruiser was faster than his American muscle, but still impressed by the bike. My bike Vs a random c7 corvette - I was crusieing the highway when this one happened and know nothing more about the car other than it was a blue c7, after complimenting him on his car at the gas station prior to getting on the highway and explaining what I had done to my bike. I was going 60 mph in 3rd gear when the c7 and I both opened them up and we were both impressed with the bike. I was able to keep up with the c7 up to 100 mph when I let out of it for my own safety. All in all I am very impressed with the performance of the bike so far, and I'm not done yet lol.

Yes the carb from the escort has power valve, it actually has 2, the main power valve for the primary and then a second one that is activated when you open the secondaries to account for the increased air flow. The second valve is controlled internally on the carb by the location of the throttle. My concern with the a jet is one the size of the carb compared to our engines and two the lack of vacuum to properly operate the secondaries.

I have posted the link to a video of the custom setup I have on my 83. I also have a post in the first ten tech section that has a lot of information and answers to questions anyone may have.

Pm me and I will give you my contact information. I am currently not a supporting member but plan on becoming one here soon and do not want to violate any of the policies of the site. My mention of $200 is what it has cost me to build the setup on the bike, not what it would cost for me to build this setup for someone. I will have to figure out final cost that is fair for anyone that is interested in having one built and if it becomes a large enough demand, after I become a supporting member, I would consider setting up a group buy with permissions from the admins.

You do not want vacuum secondaries on our bikes, they do not create enough to use the full potentiAl of a carb like that. The carb I am using in my swap is a progressive 2 barrel not a vacuum carb, the secondaries are opened manually depending on how agressive you are on the throttle.

I'm the complete opposite, I'd rather not clutter my bike with electronics. If it were a different style bike that a carb wouldn't look right on then ok but I love the look and the ease of tuning. I doubt it, I emptied the tank and resealed it as well as all new line and filters

Well I have attached some pictures crime the build process to help show exactly what I did to buod this set up. As of last night I did discover the fist downfall to this set up that will be addressed as soon as I get a couple other projects done, the builders projects are always at the bottom of the list when running your own business lol. The issue I discover last night - As I was leaving a friends house at about 11:30pm (51 degrees out) I noticed that the bike had a stumble at lower rpm and after crusing for a short time at 3-3500 but was fine after cracking the throttle and at higher rpm. When I got back to my shop I inspected the set up and found that front had formed on the bottom of the intake collector, I removed the carb and found gelled fuel in the in the intake. The fix for this issue - I will be adding a coolant heating chamber - heated by the coolant of the bike - to keep the manifold warm enough to eliminate the gelling fuel issue. If you a have decent welding skills and patience, this is a very easy modification to perform. Carb - holley 5740 bought new off eBay Intake runners - 1 5/8" 180 mandrel bends bought from hellsgatehotrods.com Throttle connection - uinlink kit bought off eBay new Air filter - gl1100 stock filter bought off ebay Carb mount - short cut 1/4" plate steel bought from a local steel supplier Machining - holes in the plate were done by a local machine shop for accuracy and cleanliness Carb to runners - 2 3/4" exhaust connector from any auto parts store ovaled to meet my needs Various vacuum caps and brass fitting all bought from local auto parts store All in all this swap has run a total of $200 at the most although the biggest variance will be the carb because there are so many different prices for them on eBay. One thing I did forget to mention in the video was that i eliminated the yics chamber and caped off the ports on the motor. I also connected the vacuum advance for the tci to the sync port on the left from carb boot.

I did not change anything on the carb, it was bolt on and go. Now the jets are easily accessible from the top of the carb should you want to change them. Knowing that I would be doing a custom free flowing exhaust I left them alone, if you wanted to use the stock exhaust I would jet the carb down but I like my bikes loud.

I have been wondering the same thing but at the moment the budgetvfot this build does not allow such upgrades to the motor. I have been in contact with the owner of UFO to try and figure out a few more options for our bikes as far as exhaust systems and performance upgrades.

I am currently unaware of the MPGs I am getting because the this setup has only been in the bike for about a week and I have not had to refuel the bike yet. As soon as I get the numbers I will post them for eveyone. I have on the other hand had a chance to test out the power of the bike and it is amazing, I have a buddy with an 02 cobra and the bike will pull away from him with ease. I cannot wait to do a few more upgrade to the bike such as coils, exhaust and brakes to unlock the bikes full potential.

Here is a little video of a custom single carb swap on my venture. I own my own shop, PKR Customs out of Findlay, OH, and am willing to answer any question anyone may have.
