2000 Magna - carb removal

[magnagregcan]

I've seen reference to carb removal and cleaning every so often, but cannot seem to find it in the FAQ's.

I think Greg or Terry posted info a while back.

Can anyone please refresh for me?

thanks.

From my experience the only "tricky" part is to loosen the carbs from the rubber boots.
3 tips;
- make sure the engine/rubber boots are a bit warm, the rubber will be softer
- loosen the boots at the carb ends, not the itake ends.
- lubricate the top inside of the boots with just a little WD40 or similar before removing/replacing the carbs

Good luck!

Thank you both for the info! I have a 95 with only 4100 miles on it and the carbs were never drained by the PO during storage. It will be interesting to see if I can remove and clean them myself. I bought the bike from Bernie in Maryland 3-4 years ago. I live in Halifax, NS (Canada) on the east coast.
Cheers!

I found the attached write-up awhile back when researching, like you.  The pics attached helped the noob in me immensely.  It's not a complete write-up on clean/shim/re-jetting, but it gets the carb bank off, shows the necessary steps to add a shim, and you can combine it with the FAQ note for the cleaning and jetting.

A couple things that I didn't see in either article, some are mentioned above, but my own notes are:

o all is easy until you remove the carb bank
o I used a pry bar wrapped in a shop rag, but like already noted, be careful where you apply force and how much.  I've also heard of someone using a tie-down strap around the carb bank and over the frame to "encourage" it.
o Go slow when pulling the bowls, vacuum chambers, etc. apart and cleaning.  Do it one carb at a time.
o Hardest part of cleaning the slow jet is knowing if it's really clean.  I'm never quite sure.  If you are re-jetting anyway, the cost of 4 additional new/clean jets may be worth the cost.  I used a couple individual pieces of copper wire, stripped out of a larger wire, to push into the jet.  Care is needed here also as the jet is brass.  Should only put something through the jet that is softer than brass.  Also heard of someone using a strand from a broom.
o Remounting the carb bank can also be a pain point.  I used the "Z" method on the boots.  I put some synthetic grease on the inside of the boots, intake and carb sides.  Then placed the boots into a "Z" with the boots hung on one side of the intake "horn", loosly resting on the other side.  Place the carb bank over the boots with the carb "horn" hooked over the other edge of the boot from the intake horn.  You may need to place/re-place the boots after the carb bank is over the intake and boots since there is so little room.  Once placed, push down EVENLY on the carb air horn plate and the carb bank should "pop" into the boots and the boots will push themselves onto the intake horns.  Note that this does take some effort when pushing it down.

First time I did this it took about 5 hours.  Last time I did it, less than 4.

The "attached write-up" posted above was too large, won't allow it to be attached....

Here's a link, complete with lots of pictures ... helped me a great deal when I first pulled mine:

Thanks again to everyone! The pictures are enough help along with the text to instill confidence; I'm now looking forward to doing the work.
If any of you ever come to Nova Scotia, please do drop in for a feed of lobster and a beer. This offer doesn't expire until I do!
Just email a week or so ahead to confirm I'm still kicking.
regards,
Greg

Wow!  It is a long ride to Nova Scotia, and at the end a lobster!!  You are tempting me big time.

I like lobster even better than beer.

Once in Maine with a singing group, a local restaurant owner liked our concert and invited us to a late night anything we wanted to eat free feed at his restaurant.  He had gorgeous lobsters, but many of my bonehead brothers ordered steak!  I couldn't believe it!!  Best lobster I ever ate.

Ok.. This is a post with several items.. Including Carb related stuff...

I have ~80K on my bike

(See attached pictures related to some of the questions I have below...

Well, I finally got up enough nerve and time to take advantage of "packge33's" great gift of some 105 main jets.
I bounced the Carbs out of my bike (my 1st time).
I cleaned out all the jets and the bowls and installed the new main jets...

I have a pilot jet question ----
On the rear right carb.. The Pilot Jet has a hole in where the D-socket goes which leads to an orifice just beyond the treads.. Anybody have any info on this and why that cylinder is different than the rest???
Another question - Under the above pilot jet, under the spring was a very small o-ring, but when I did the last pilot jet, it did not have an o-ring.. Are all of them supposed to have o-rings, or just that one?? Come on.. Someone help me out here!!!

I was able to adjust all my pilots to 2 3/4 turns out (one was at about 3/4 of a turn).

I also drilled another (making two total) hole in the back end of my exhaust.

The result of my work eliminated most of my hesitation and greatly increased my mid-range power.. Unsure of any MPG effect yet..

Another Question.. All of my Intake valves have quite a bit of carbon build up on them.. I use good gas and SeaFoam from time to time and was surprised at the amount accumulated. Should there be any concern here???

This is for Terry.. I finally did the Gas tank breather hole mod... There is actually a maze of metal on the front side of the filler hole, so I drilled one hole to the right of center to not effect the purposes of the maze (whatever that is, probably to prevent slosh into the vent tube). I haven't tried filling the tank yet..

Hoot,

O-Rings go on each pilot screw, you are missing 3. You should have a washer than an O-Ring so the spring tension is on the washer, not the O-Ring.

I have been too busy to work on anything, several bikes are in pieces in the garage. One day I hope to have time and get back to the bikes.

The vent tube I think has a splash guard in place so maybe you felt that. I was thinking of doing the hole on the Side of the neck not in the front but either should be fine. Waiting for the the fill-up now...What size hole did you drill?

Hard to tell how much carbon you have, if it is a concern you might run RXP through your system, never used the stuff but read lots of good things about others who have. No one I knew so credibility I can't confirm. In cars we use to poor transmission fluid down the carb to remove carbon also used water (which is not recommended., water does not compress, you can bend a rod).

The hole I am not familiar with and not sure I understand what you are referring to yet so maybe someone else can chime in.

and what is the foil for, are you cooking your carbs.

Check up in the hole should be an Oring there. I would like to see a pic of this hole or orifice by the pilot jet !!!

The Hole is in the middle of the "D" and leads to a horizontal rectangular orifice just below the threads.. it is a very small hole, but a hole none the less..

It sounds like I should at least have o-rings in all of the pilot jet holes under the springs, when Honda cleaned my carbs, they must of lost it..
I wonder if you can just order those parts??? A couple of my "D"'s are pretty messed up, I wonder if there are Pilot "kits" with the springs and o-rings etc... 

[roboto65]

So there is a hole in the needle it's self if so I HAVE never seen any holes in the pilot screws sure would like a pic of that !!!

I can see all the other pilot screws, but since it is the right rear, there are coolant hoses in the way of that one..
