Hey man so I just got a CB550k 77'.... and I purchased a MotoGP Werks exhaust for it and going to run pods for the carbs ... what jetting and settings do you suggest for the carbs ?
So this is a super tricky question because it varies so much across bikes, location, other components and so on. I’ll give you some pointers that may get you close.
Let’s start with the basics:
-Make sure that all of the intake rubber boots are in a great shape. No cracks, no leaks. If they are then replace them before trying to jet.
A vacuum leak is your worst enemy.
- check your throttle linkage is working properly. When you turn the throttle wide open, insure that the slides are all the way up. When you close it make sure the slides go all the way to the bottom.
- Bench Sync the carbs before you start tuning. Screw the idle adjuster in until you can just fit the smooth side of a small drill bit into the gap between one of the slides and the bottom of the intake opening. Almost like a round thick feeler gauge. Adjust all the other slides to that gap. Then drop the idle adjustment screw so that the slides bottom out. Then turn it in so that the slides just barley lift. This is your initial idle setting. Once the bike is running you can dial this in.
Once the bike is running you need to do a proper carb vacuum synch. This is essential.
Jetting:
Set all of your air/fuel screws to 1 1/2 turns out from lightly seated. Do not tighten these in with a lot of force, it can break of the tip and ruin your carb.
Start with stock size pilot jets. This controls idle to 1/4ish throttle. You have a small range of adjustment using the air/fuel mixtures think of the air/fuel mixture screw as going up or down about one size in pilot jet.
If it’s lean it will sputter almost like a dry cough. If it’s rich it bog.
The the needles control 1/4 to 3/4 throttle or the mid range if the power. There is some overlap between fuel circuits so a change here will have some effects on the pilots and mains. Start in the middle clip position and test.
Go up on clip position (drop the needle down) will lean it out. Go down on clip position (bring the needle up) will make it richer.
ONLY USE OEM Needles: the overseas stuff I’d the wrong taper and will cause you a headache.
Same thing applys:
Lean will sputter. Rich will bog.
The mains: They control wide open throttle. This is the most about of fuel the engine can get. Picture a fire hose wide open.
With your exhaust I would bump these 3 main sizes. I may be wrong but I believe stock for a 77 cb550 is 98 or 100. Whatever the stock number jet is I would go 3 sizes bigger to start.
Same deal: lean will sputter, rich will bog.
It will take some time, trial and error but you can do it. Hopefully this info made sense and good luck!
@@kylevara thank you so much man, any good plug for oem jets or rebuild parts ?
One of my brothers is giving me a 74 cb125s.. only does 60-65.. but it's a fun lil bike... was gonna turn it into a cafe racer and ride it back n forth to work..
Great video! Definitely some good info with the carburetor and air filter system.
Honda's are the best man😭❤️🔥❤️🔥👊‼️
Cool info. Thanks for posting.
Hahaha holy crap actually freaking out about this, thanks for making the video your inspiring me to make my own even more now!
I heard that larger main/secondary jets has made it easier to work with pod style filters, is that not true?
I'm working on my cb500 cafe project and was wondering how you mounted your rear brake light
Custom rear subframe I think
