Keihin VD51A Carbs from the Magna V45 - What a MESS!

[@IsacSebastian-e7m]

Hello from Romania, Europe. Man, you're fantastic. It's the first time I've seen someone explain everything so well. You saved me a lot of headache. If I was closer, I'd come over to thank you personally, have a beer and chat.

Great Video. I just pulled my carbs today off a my 1983 Honda Magna V45. Float issues. One needle wasn't even hooked up on the float Carb 1. Insane. Somebody did that to the bike because its the easiest to get too. I bought this bike over the winter and their mechanic said it needed a total rebuild. I hope the flooding of gas didn't wreck the cylinders. Doing the same job as in your video. Too much gas leakage and now I know why.

This is great advice! I’m glad I found this while I already have the carbs on the bench

I had the same problem with the jets being seized. How I got them out was to put a screwdriver blade in the slot and gave them a sharp rap on the screwdriver handle. They came right out after that. Of course you then have to replace them with new ones

[@MotoRestoFL]

Yea I have done that and tried with a regular screwdriver, but the handle as you eluded to absorbs too much energy.

[@johndpearson64]

@@MotoRestoFL You are correct. Thinking about it I realized that I used the steel shaft of a screwdriver with the reversable flat/phillips blade, without the handle.

[@unleavenedkaraiteplus3412]

This is why: Magna, Intereptor and Sabre VF carbs all have two shorter and two longer springs because the front carbs are set up as "downdrafts" and the rear carbs are set up as "sidedrafts". The different spring lengths balance the vacuum across the carbs. Gravity and weight play a part in how fuel and the slides move because of their orientation. The main-jet holders are also different for the same reason. P.D. Don't mix up the parts to avoid problems; but then again, unless you know which carbs takes which, we won't know how to correct it had someone been in there already !!!

[@MotoRestoFL]

You are absolutely correct. I hadn’t thought of it that way. Even though I read the up/down draft in the service manual. Thanks.

[@MarcinZukowski-c6i]

Great explanation! (Subscribed and liked 😊) Where can I get the workshop manual for V45 Sabre from. I bought 2 for a full restoration (the goal is to have one on the end of the work 😜) Martin

[@MotoRestoFL]

Sorry for the delay. I don’t get to comments as often as I should. Just Google it and you’ll fine perhaps several links to download it.

[@shaunhardie6077]

Really good informative video, and well explained too 👍. When you were explaining about the pilot jets being super tight and using too much torque to remove them worrying about snapping the top of the screw head, maybe make yourself a "special" tool to avoid that happening? I had a bit of a brainwave (scary I know right), could you just machine the tip of a screwdriver to fit inside a tube that fits snuggly over the OD of the pilot jet thus making the screw head unable to shear off? Hope my description is understandable. Anyway, great video as always Tom, 👍😎.

[@MotoRestoFL]

I thought exactly that but at this point I’m leaving it alone. Next time they come out I’ll do a tear down to bits and if necessary machine the jets out and replace. Right now it runs great so that’s maybe a couple years out. Hopefully. lol.

[@shaunhardie6077]

@@MotoRestoFL 🤞 you never have to do them again Tom.

[@henryhawk978]

Enjoyed the video. Where is the best place to get carb parts for my 96 VFR750. RIDE SAFE!

[@MotoRestoFL]

Check with v4 dreams dot com. I don’t know if he supports that new a unit but his stuff is excellent quality.

[@henryhawk978]

@@MotoRestoFL what's the new A unit? I was looking on Partszilla and they listed VFR750 A and VFR750 AC.

[@MotoRestoFL]

@@henryhawk978 autocorrect error. I meant newer unit or newer model bike. I know he has older VFR stuff.

[@jimrocket3452]

Can you replace the rubber diaphragms without removing the carbs from the bike?

[@MotoRestoFL]

Doubtful on a V4. On an across-the-frame four, yes. But these aren't accessible to that degree. I never tried, though. Never know.

[@jimrocket3452]

@@MotoRestoFL I found out that you can. Two of them just the gas tank you lift up. The other two you have to take off the radiator to get to them.
