Kuryakyn Hypercharger install

[PGunn]

I have looked all over and could not find any articles on mounting these on a Venture, I have an '06. I picked up a pair on EBay which are real left and right hand Hyperchargers from a Harley with a CV carb mount. I have mocked up the right side and the mounting is a lot easier then it looks. I'm waiting for some parts to come in so I can have the right side finished mounted before I start the left side.

 

Now I am mounting these for looks alone and I have no intensions of setting these up to work as ram air intakes because I do not want to cut holes in the lower fairings and route the duct to them. The mount I have working so far is by using the original Yamaha intake mount and by cutting it down to basically a flat surface. After getting it to fit reasonably flat to the Hypercharger I drilled the mounting holes through it using the Hypercharger hole pattern as the pattern. Next I glued a piece of 1/4 inch rubber to the mount this helps cover the rough surface and will allow the 5/8 spacer (5/8" CV bolt pattern Spacer: J&P Cycles) something to seal against. You need around 1 inch spacing between the Yamaha mount and the Hypercharger to get the right side to mount without any interference.

 

I have been looking over the right hand Hypercharger and I noticed that even if you bought 2 right side units (standard with the CV Mount) one of them can be converted to a left using a hot glue gun to mount the screen to the opposite side of the case. This is how they did it and the mounting hole locations are of no difference because of the way I'm mounting them. You need to buy the CV Mount Hyperchargers because they have 3 mounting holes and the back surface is flat and the bolt pattern is in a circumference around the hole. Once I have them completed I'll upload an updated install with pictures.

 

Now as a side note I worked on least a 1/2 dozen different ways to mount these right down to machining my own adapters and mounts out of aluminum. After planning everything figuring prices and not counting my own time I found that buying the Yamaha intake mounts (SKU: 4XY-14431-02-00 $13.00 +/- each) and cutting them to fit (they are a rubber / plastic material) was a lot cheaper and easier, You can cut it with a hacksaw and then belt sand it flat. The CV spacers come in 3 different sizes 1/4, 5/8, and 7/8 from J&P Cycles. The 1/4 inch thick rubber I had but I did lookup on EBay and there is some 1/8 inch thick on the site and with the 7/8 thick spacer it should work just as well.

 

Attached is the picture of the model of the Hypercharger I am using. I also have tried to lookup the left side unit (600178 number on the side of the box) and can't find it anywhere.

I have completed the install and attached some pictures of it completed. I also attached a zip file with the install instructions in Word format and and in Adobe PDF format.

Now that is one fine job you have done there.

 

Those are different and look really good. What type after market filter

you going to use in them??............................Ron

[MikeM8560]

I knew alot of rider who added other air kits and just used a hyper for the looks hooking up to the vacume lines for the butterfly.

. I had one on my v star, funtional. looks good on your but with the cowles it will block the butterfly action.

[PGunn]

Thanks, it only took around an hour per side to make them and K&N makes replacement filters for them. All the work on them was done using a saws all and a belt sander. It really was pretty stright forward the only testing was making sure the correct spacer was installed.

 

The butterflys will work but your right they for the most part hidden and not having the ram air setup makes using the vacume setup usless anyways. Without the vacume connections they stay open all the time and act as a passive intake anyways.

Great > Write -up! Thanks!

Ok I found that these really do open up the breathing on the intake side. I took the bike out let it warm up some and started down the road went to twist on some power and got a quick surprise it was the “wait where is it, where did it go, hey there is nothing there, where is all my power gone to… really it was those exact thoughts that went through my head. After installing the Hypercharges the mid and upper range are flat, no power, and little acceleration. Now after the shock passed I shimmed the needles and that helped some but the flat spot / no power is still there until the revs go up so I will have to re-jet. I went to the dealer, ok now atop laughing it isn’t that funny, but I was told that the 02 and newer have different carbs an the jet kits won’t work because all the jets are now the same size.

Now my question is what type of jets are they? I have looked, Googled, and can’t find any info on these carbs and what jet types are in them. Now I do know these are Makuni BDS32 but from what I have seen there is nothing out there information wise. I also emailed Dynojet and asked about a kit and was told they had no plans for a kit. So can someone let me know where to look and what type of jets and sizes you would recommend?

[bowa1]

I don't believe there's ever been a jet kit offered for the Ventrue but below is info on the stock jet sizes. As you'll see, there's 3 different sizes used for the 4 carbs. As long as you get Mikuni main jets you'll be good to go as far as them fitting in the carbs. As far as what sizes to use... your guess is as good as mine. Without having the bike on a dyno it's going to be a crap shoot. To do it correctly you need to have it on a dyno and someone that knows how to use one properly. While the hyperchargers are an improvement in the "looks" catagory, I think they're going to cause you problems unless you have access to a dyno machine to properly jet your bike. Not only will the main jets need changing, the pilot jets, the mixture screws and needle positions are going to need attention as well. Good luck with the project. Larry

 

 

Carbs 1 & 2 use a 122.5 main jet Carb 3 uses a 117.5 and Carb 4 uses a 120. You should be able to find Mikuni jets at your Harley dealer and order them from any bike shop or online.

[Carbon_One]

You really don't need a "kit" . Just replace the mains 1 size up and the same for the pilot jets too as a starting point. I did that and I'm running the K&N filters in stock breathers and while the bike ran OK without rejets I feel that doing so gave the bike better low end and throttle response. It also inproves cold weather running. Mileage may have suffered a bit but not by much if any. On your set up you may need to go a little bigger than the 1 size up thou. Just depends on how lean the carbs are running as it is now. Stock pilot jets are #15, replace that with a #17.5. Stock mains are #117.5 , #120, & #122.5 (2each), replace only two of these , move the other two to a different carb. purchase a pair of #125

http://www.motorcyclecarbs.com/ is a good source of carb parts too. I'll look tomorrow for the jet model #'s

HI PAUL,

FIRST OFF THE HYPERCHARGERS LOOK GREAT!

NOW, THE FOLKS AT MORGAN CARBTUNE (THIS COMPANY MAKES THE CARB. SYNC THAT MANY MEMBERS SYNC. THEIR CARBS. WITH) ALSO MAKE A TOOL CALLED THE COLORTUNE. THIS TOOL ALLOWS YOU TO ACTUALLY LOOK INSIDE THE COMBUSTION CHAMBER WHILE THE BIKE IS RUNNING (I KNOW IT SOUNDS IMPOSSIBLE...BUT IT'S TRUE)

I HAVE PERSONALLY USED THIS TOOL TO REJET MY V65 MAGNA AFTER NEW PIPES WERE INSTALLED. HERE IS THE WEBSITE: http://www.carbtune.com/ SCROLL DOWN ON THE MAIN PAGE AND YOU WILL SEE IT. IF YOU CONSIDER THE PRICE OF DYNO TIME THIS MIGHT BE A GOOD INVESTMENT. ALONG WITH THE TOOL ITSELF, YOU WILL GET A CHART THAT TELLS YOU WHEN THE OPTIMEN COMBUSTION HAS BEEN REACHED SO YOU CAN CHANGE THE JETS, INSTALL THE COLORTUNE IN EACH CYLINDER, AND REJET IF NEEDED.

JUST A THOUGHT.

EARL

All this for looks? Am I missing something here?:confused24:Is this something like long horns on a car or t**s on a bull?

Earl, the main jets only come into play at or near wide open throttle so the colortune isn't going to do what a dyno can. The Colortune is helpful to set your pilot mixture but not when determining main jets, etc.

Obviously you are missing something... It's a thing some of us call customizing

 

Definition of customize (verb)

forms: customized; customized; customizing

to make or to fit according to individual needs or desires; to personalize; to individualize

 

PGunn... Nice Job!! Good luck with the jetting and keep us posted on your progress... I applaud your ingenuity and have thought about a similar modification myself and am very interested in how yours comes out.

 

Don't let any naysayers get to you.. Some of us are very interested in your project.

 

Thanks,

[Stratcat]

VERY UNIQUE!! Cool idea and great job!

What ever you do don't go looking for the "Fuel Injection" on a Venture.... Now that project is looking better and better also.

 

Thanks guys for the info and as soon as I get it figured out I'll let you know and that colortune I did see what has been done here in the group and the effect of it and I may get one as it will come in handy when tuning the fuel injection setup I'm working on. I should have the jets figured out by no later then the end of June as I am planning on biking from Boston to Buffalo the end of the month to see the grandkids.

[dynodon]

I say great if people buy this as a looks sort of thing, but really, unless you speed most of your time beyond 100 mph, there really is no ram air effect.

 

I sell K&N filters and tell people that they are great for racing, and peak power, but don't buy them for MPG or regular street driving since they really only have an advantage over a clean plain filter at high rpm and BIG throttle openings. For most people 98% of your driving is done at about 15% throttle opening.

 

I think the hypercharger looking units are cool looking, I just am dubious about any real benefit for the average rider.

[PGunn]

Don I have to agree with you on the any benefits thing. I didn't compare the K&N replacement filter for the stock intakes and they may open the breathing up just as much or close to it. I also did not cut an opening into the lower faring on each side either or run any special ducting but the bike is breathing better then it did with the stock filter setup and it does look "cool" with them on there and I did it for around $250.00. As far as "ram air" goes I think it would take a lot more then a intake getting hit with 60 mph wind in a area where air turbulence is a major factor and not smooth by any means. Now if someone were to develop a supercharger of sorts that would make a difference but how many would really need it and the cost would be real high.

Good Luck on the RSV when using the color-tune to view

the front plugs though.. I wish you success.

Didn't mean to denigrate "customizing" ! What I realy meant is that if you are going to customize with something functional then it ought to actually function and not as I said be just "t**ts on a bull. "

Prior to the Venture I had a Kawi Nomad "99, first one-no fuel injection" .

I changed out to Cobra pipes, removed the EPA stuff, reed valves etc... Removed the airbox, and Installed an exposed K&E filter on a Thunder Manufacturing plate at the carburator. Obviously, had to rejet.

The rusult was incredible - it raised both torque and horsepower by close to 25% at virtually no loss of MPG and furthermore you could actually breathe behind it since even without the EPA crap it burned more efficiently.

Now, thats called "functional customizing" . Not just useless glitter. Sort of like the Diamonds vs Zircons argument. A 10Kt Zircon is still a worthless piece of glass.....

You should have let it go after your 1st post.. This Man is really customizing.. Not bolting on goodies he found in some catalog .. He's thinking outside the box and working the bugs out seeking advice from fellow VRs.

 

You calling it "useless glitter" and comparing it to a "worthless piece of glass" is rude, ignorant, and crass in my opinion. I would like to say more ...GGGGRRRR

 

Do yourself a favor.. Next time you think stuff like that about somebody's bike or their work on their bike.. KEEP IT TO YOURSELF

[MAINEAC]

Don are you saying you don't see any "real world" gains in a K&N upgrade on a RSV? Because I was thinking of doing this myself.

[PGunn]

You really don't need a "kit" . Just replace the mains 1 size up and the same for the pilot jets too as a starting point. I did that and I'm running the K&N filters in stock breathers and while the bike ran OK without re-jetting I feel that doing so gave the bike better low end and throttle response.

Larry

Larry thanks and you were right on. I moved the #120 Jet to the #117.5 carb and then moved one of the #122.5 jets to the #120 position and bought 2 #125 jets and that solve a large chunk of the problem. I still have to replace the pilot jets, should have done that when I had it all apart, because I can still feel a small lag when I get on it. Under normal driving you really can't tell that it needs it but as soon as you jump on it you know it is there.

Now for the "reasons why you have to check everything" part. You guys out there who are tempted to do something like this be warned if you don't check everything as you put it back together you can run into major issues. When I started taking the stuff off the bike it looked straight forward and easy to do and it was. Remove the tank, disconnect a few hoses, remove the air boxes, remove the carbs, flip the carbs (oh yea make sure you have a large rag under the carbs if you didn't run them dry before starting and a good size one even if you did because they are going to drain the leftover gas out the top of them when you flip them), pull the float bowl covers, remove / swap the jets around and reverse the process to reassemble. Now make sure everything is free and none of the hoses get kinked because it cost me 3 1/2 hours sitting on the road side because I kinked the crankcase breather hose. Now When the crankcase can't let the pressure out it will build up until it finds a way out which in my case it blew a seal. I was lucky I did no damage to the engine and the dealer it went to was great, Hudson Cycle Center in NH. My mistake ended up costing me $168.00 in parts and labor plus $30.00 towing all because I did not check all the hoses.
