Installing new main jets in CB550 carbs?

[Duc]

I have some new main jets coming for my CB550 carbs. (Keihin carbs)

Is it a simple job to fit these? ie do I need special tools and a setup once I have done it?

I am thinking that I just drain the carbs, remove the bowls, pull out the jets and throw in the new ones - is this over simplifying it somewhat?

Not sure how the jets are held in? ....threaded maybe?

Can this be done without pulling the carb set off the bike?

BTW - The carbs have been recently fitted with new carb set and balanced and tuned. Reason for new #110 jets is due to removal of airbox and fitting of pods.

Yes it is

ie do I need special tools and a setup once I have done it? not really

Nope you pretty much got it right there, depending on what type of jet they take you'll need a Phillips screwdriver to get the float bowls off and either a smaller socket/spanner or flat blade screwdriver to change the jet

They are threaded into the carb body and it is very unlikely you'll be able to do it without removing the carbs from the bike

Probably not totally necessary but I'd be inclined to rebalance them afterwards to be on the safe side and I'd look at dyno session to make sure the jetting is as good as it can be

Thanx for info. You have given me confidence to attack the carbs.

I am reasonably handy and rebuilt the bike from a pile of bits - Cafe Racer...but I have never gone internal on carbs before.

EDIT: The jets just turned up from EconoHonda and they are tiny, non threaded and with a tiny O-ring. I guess they just insert into a tube?

Kick has it bang on--only word of warning--Make sure you use a good quality screwdriver. if ya smear the heads on the bowl screws it can be a bugger to get em out

and dont over tighten the jets, just do it up till its tight. put no pressure on it at all.

Oooh. That went well. Easy peasy....

If anyones interested. The CB550 jets are just pushed in to a tube and held there by a spring device that contacts the bottom of the float bowl. They are not threaded and no special tools are required.

I basically did as the advice given and I am well pleased with the result. I recomend removing the carbs and the tank to do this job (as I did.) Whole job took maybe 90 minutes. Slightly easier for me because I have pods (no airbox)

Thanx all.
