A not to this thread. I sold this bike last June. The new owner called a week later saying that it has lost power an was smelling of gasoline. I took the bike back to my garage. Acted like a carburetor problem. After I pulled the bowls off all 4 carbs I discovered that on of the jets on one carb had unscrewed itself and I was able to pull it out with no effort. The only thing keeping it from falling out completely was the bottom of the bowl. I also noted that the velocity stacks had come loose. After fixing the carb and fastening down the velocity stacks I gave it back to the new owner. He said it was now running amazing and much better than when he first bought it. A couple months later he texted me from Yosemite Park with a photo and a message that he had put 3,000 mile on it and was still going strong. The lesson to be learned is that if it is not tight then the vibrations will certainly unfasten it over time. Torque the jets in and double check them. Just finished up a fuel injection retrofit of a 80s series Honda Magna. Lot of fun and a learning experience. Now starting on fuel injection project of a 1999 Kawasaki ZG1000. Check out some of my other videos. ruclips.net/video/3bbu6AfAPQ8/видео.html
@@johnpost3567 Actually I did do a 86 magna fuel injection but if I were to do it again i would do it differently. My project involved making a custom manifold with injectors and all. It was a real pain. I have since learned to do it differently. I converted my Kawasaki concours to fuel injection by placing the injectors in the airbox and using the carburetors as throttle-bodies.

Just want to say first: Do NOT pull off those funnel air intakes on the top of the carb! They are usually held in by small tabs that you or previous owner broke off. Very common mistake on these bikes. Now that I got that out of the way. Great video! Great video quality and good audio with good and detailed descriptions. I also love the home made ultrasonic tank!
From what I've seen on other videos,,,, you remove the 4 screws around the bottom first,,,, then turn these funnel velocity stacks counterclockwise about a half an inch,,,, they have an ear inside that will line up with a slide and pull up. out,,. ???
My bike had been worked on before. The stack were just pressed into place. Easy to remove them...Don't forget to put them back in. You will loose horse power without them.
MY rubber boots are not new but they are not brittle by no means. Nothing wrong with the boots just the clamps fitting loose around the boots even though the screws are tightened all the way down. Figured the loose fit was causing my rough idle problem but apparently not. Your video encouraged me to take apart my Magna cabs. Cleaned them and synchronized them on my bench and I'm riding happy now. Apparently the loose clamps around the boots does not affect the performance. Thanks for the reply and your awesome videos.
Ricky G. Same thing happened to me, I’m not sure how my boots got loosened but I saw one of the clamps got bent and deformed and is spewing gas all over one of the carbs
This video shows why I sold my 99 Magna....great bike , but if you dont ride often...and drain all 4 carbs....she will give you trouble, bought a Fuel Injected Suzuki....peace of mind on every start no matter what.
Every bike I had in Colorado required a carb cleaning every spring. The reason was the ethanol in the gas. I found a place where I could buy ethanol free gasoline and the solved it. But I went ahead and converted three old classics to EFI .
Queston: is it normal for those four rubber boots at the bottom of the carbs to be slightly loose? Mine wiggle a little when I thought they should be tight. The screws appear to be bottomed out already but still have a little wiggle in them.

@@gerrypineau A friend of mine swap this engine into a 4 Wheel. He is using an external fuel pump, but he wants the engine to run like factory spec. Does your bike have a fuel Pump?
my vf750c is hard to start when cold, after it works the 2 exhausts on the right side are cold for some time and the bike works failing, I have to accelerate at high rpm for the carburettors to unlock and then it works fine, but when it is cold it always happens the same. What could it be? thanks
If the exhausts are cold then there is no fuel being burnt on those cylinders. Either the carbs are clogged or the plugs are not firing. get it started and check if there is any exhaust (combusted) coming from the pipes. I think you should pull all 4 carbs and do a thorough cleaning.
@@gerrypineau Thanks man, I took the bike to a mechanic who cleaned the carburettors and it was fine, after a while it was the same. It has been parked for about 10 years, it has 7000 km. I understand a little mechanics can I do the cleaning or is it difficult?
you will absolutely need to tune them when you are done. you can get really close while on the bench then after they are installed you can tune them with a simple setup. I have videos for both. ruclips.net/video/PjERD-Ko6FM/видео.html@@claudiorodrigues1120 after install. ruclips.net/video/sfdEehWDtXE/видео.html
Hello, I noticed you have the same bike. Do you know what the center tube is directly on top of the V in between the heads? I have fuel leaking from the top left side. I’m sure it’s a gasket. Just don’t know which part to order. Thanks
@@gerrypineau Hello, question about the ports on top of the engine. Right in the middle of the V. Do you know what That part is called? I have fuel leaking from left side right behind the choke lever
@@user-nb5zq3cj4j There is one hose that I know of that is open to the air and connects nowhere. Install the carbs, twist it 90* to the left and forget it. It is a vent tube for the carbs - it DOES NOT connect to anything. It is often refered to as "the snorkel".

Hi Gerard,
Do you have a guide on how to retrofit the fuel injection onto an 80s Magna? Will that method work for a late model 3rd gen Magna?

Stopping by just to say thanks!
never saw a 3rd gen done before.i know the 1st gens are a real jewel too.but the effort is usually rewarded nicely.

Hi did you fit the headlight yourself if so what bike was it off cheers Jimmy
Those air intakes, you dont have to take off them at all. The carb comes out sideways anyway. Btw, nice video.

Mine will wiggle when the screws are backed out but not after i tighten the screws.

CANT UNDERSTAND A WORD BUT I KNOW HOW TO GET IT APART
my little 'turbulance rams' or whatever those 4 tubes are, dont come off like yours... looks like there are tabs under the metal bottom airbox
Exactly right. I had previously removed the hold down tabs last time I took it apart.
