Cheers,
That's actually the "problem" with the V4 engine - those carbs are a motherF-bomb'r to get off. And that's the "easy" part. Wait 'til you go to reattach them to the bike..........

Just a quick FYI - they are a "unit" - and attempting to remove them piece-meal will result in the purchase of new carbs (well, used anyway), or a stupidly-expensive trip to a carb-specialist at the least.

You can go-ahead and attempt the Berryman B-12 or Seafoam treatment, but it's not likely to get you anywhere.

The carbs (each!) have two jets in them - main and idle (or primary). The main jet is fairly large - the part that holds it is what the needle on the slide moves in and out of as it cycles up-and-down with each intake-pulse. They don't plug very often (although there are tiny emulsion-holes drilled in a small tube inside that assembly that CAN plug, but good gas and/or a small bit of cleaner in the gas can fix that easily).

The primary jet is a different matter - typically the hole through it runs anywhere from 0.004" to 0.010" (two to five times the diameter of a human hair), depending on how-much cylinder it has to feed. They plug with varnish quite-easily, and often must be removed from the carb to clean them (by spraying-through them with carb cleaner, and possibly poking a fine copper wire through them - copper will not damage them, steel or other materials might).

"Well", you sez, "It idles just fine on CHOKE - why won't that clean out the primary-jets if I put cleaner in it?"

Because, that "choke" isn't a choke - it's a valved vacuum-circuit allowing the engine to draw fuel through the main jet when the bike is cold, as well as the primary. Essentially, the main jet fuel is all the bike gets - when you shut off the enrichment, the engine has no fuel and stalls. NOTHING is flowing through the primary jet(s) in the first place - hence it's almost-always an exercise in futility to add carb-cleaner to the fuel tank in hopes that will fix what ails you. But you can try it, you might get lucky. Don't over-do it though: see the next paragraph for why.

As pplasm noted; any rubber parts (specifically the slide-diaphragms and gaskets, and any air-cutoff valves) that come in contact with carb-cleaner will soften, swell, and stretch out of shape - making it hard (if not impossible!) to correctly reassemble the carb without obtaining new ones. In the case of '80s and '90s motorcycles, those carb-slide/diaphragm assemblies are becoming rather scarce, and are scary-expensive (as much as $200 EACH!) when you DO find them. So, clean 'em with soap and water if they're cruddy.

And as to that spray-carb cleaner - make sure to use eye-protection: you've GOT to spray into each and every orifice on each carb to ensure that they're clean. That spray HAS to come out someplace - if the exit is aimed at your eyes..... well..... That. Shat. Hurtz.

Now, as to removal and reattachment of the carbs: do yourself a favor, and look up your bike on ronayers.com or servicehonda.com, find the exploded-diagram of the carbs, and order yourself four new "carb insulators" or "insulator boots" - the rubber part that goes between the head and each carb. Yours are now 12-years old, and are almost-certainly hard and possibly even cracking or "going gooey" if there's been a lot of fuel-additives used in the gas. The old ones can be a source of a vacuum-leak, as well as new ones will make it far, far easier to get those four carbs back-on in their proper locations. Is there anything that looks like "oil" in the vee beneath the carbs, but there's no actual "leak"? If so, you NEED new ones. Now.

Burley,

Nothing personal, but the regulars on this site tend to 'have fun' with everyone.

As you've seen, if you ask a half-intelligent question, you will almost always get one or more very helpful answers. And whatever Ken - sorry, 'Morbo' comes up with.

Welcome to the site, and keep us posted on the old V-4.

Thank you Air-Hawk. A well thought out reply aimed at a person with some intelligence, not alot but some! And yea I remember geting carb cleaner in the eye and many a cut working on my old YZ 125. Doesn't feel much better in cutts on the hand either.

I think my excitement got me wanting to rush the process. I'm sure all of you can understand not having a bike for a very long time and then getting one again and wanting in to ride...and ride quick! I know I'm going to need to take my time. I guess I'm a victim of typing out loud sometimes. Especially when then idea isn't a good one. LOL.

I'm going to go ahead and try and gas treatment carb cleaner and pray to God!! I'm just hoping that since the bike was regularly maintained up until a year ago that I shouldn't have to much gunk in there. But I wont really know until I can get that tank off. And once I get the tank off I'll use some spray carb cleaner....very carefully of course, in all orifices.

Were getting record weather here in AZ. Nasty rains and snow predicted for the rest of this week. Really hoping all this crap clears up by Tues. I need clear skies so I can get this baby wrenched!!!


@pushrod--Nothing personal and no offense taken. My thinking is that someone new that comes to your community and is asking questions...members would want new members to stay and hopefully be able to help someone else down the road. This is done with courteous, tactful responses. There is a fine line to walk when your just "having fun" with someone or your like I said making them out to be an ass. Someone might have come across that reply and said..."well screw this community I'll go somewhere else" And that may be fine with some or all of you I don't know.

Just to let you know where I'm coming from. I'm a moderator at one of the worlds largest on line gaming community's for adults. Home | TOG - The Older Gamers. We have over 40k members from all over the world. I've been with this community for over 9+ years. Our moderators, admins, founders, and members try to do our best when dealing with new members or just people with questions.

I look at it like this. If I'm going to spend the 2 minutes it takes to actually reply to someones post, I'm going to try and help them the best I can. Don't get me wrong I like a good ribbing just as much as the next guy,and love to joke around with fellow members. but again there is a fine line between making a joke, and making a snide remark.

Sincerely thank you guys for all the great responses. You all have givin me a good starting point and some good ideas and things to look/watch out for. I'll be sure to stick around and keep you all updated on my progress. I'm sure there will be many more questions along the way. I'll try to think out my questions and replies a bit better in the future!

Thanks again,

-==Burley==-

Hey Burley, during the '90's I worked in a cycle dealership and fell in love with the Magna. During that time I had a few used bikes, a couple Viragos and a Maxim-X but never a Magna, just couldn't afford a new bike.

Last march my wife says lets get another bike, and of course who am I to argue with her. I decided I could probably afford a Magna now that they were 15-7 years old depending on the year, so I began searching. I wanted the yellow one most and found one that seemed right in a town about 120 miles from home, only bad news was that it had sat in his garage for nearly a year with gas and fluids in it. I drove to the guy's house, and did a thorough visual inspection of the bike. No fork seal leaks, no visible engine or trans leaks, chain, cables and hoses all in good shape, carb boots still supple and not hardened. The bike fired quickly and idled with no problems. After about a 20 mile test ride I bought it on the spot and drove it the 120 miles home with my wife in the truck behind me. This all on a bike with 22,000 miles on it when I bought it.

Long story short, I absolutely love this bike. It's comfortable, fast (fast enough for me) and just plain cool. Never a fan of quiet bikes I added Cobra slip-ons to give the exhaust a throaty but not obnoxious note. Between march and october I put over 5000 miles on it, the best ride of the summer being up the east coast of Michigan and over the Mackinaw bridge. Over 300 miles in one afternoon and no sore butt.

I really hope you get your bike running with minimal effort. I'm certain you have a much longer riding season in Arizona than we do here in Michigan. Enjoy that beast!

Now that's a story I like to hear!!! I've been doing a lot of research on stored bikes and starting and the likes. I really don't expect any trouble. I'm going to replace the battery and the fluids and start her up.

I brought her home couple days ago. Here is a link to some pics for you guys. She is very clean. Only damage is a dent in the tank. I'll worry about that later. Other than that she is perfect. I'm going to remove the windshield here in a few minutes. Then get to work on getting the tank off.

Bike is home!! | Facebook

Cheers,

Bike looks great. I don't think those are the stock pipes, maybe Vance & Hines? So it will probably sound pretty sweet.

Here's a link to a promotional pic from Honda with the stock pipes, notice the ends are different...

Here's a Youtube video of a Magna with the Vance & Hines pipes.

Any update on the status of the bike?

LMAO now THAT was funny!!!


Update: Got the tank off and drained today. Have to go have it re-keyed tomorrow. Tested for spark and all is good there for sure. My buddy can personally attest to that!!! He got a bit of a shocker

So all that's left is inspect the tank. Clean if necessary. New fuel and fire her up.

And yes my pipes are vance and hines. That video is sweet!! I will be very pleased if she sounds like that!!! Thanks for the links!

Cheers,
