Topic: How ro ID jets and request for recommendations

[hiljak]

Bike is a 1978 CB750 F3 Super Sport


How can I tell the size of jets that I have. I've pulled out the main jet? and I don't see any identifying marks on it.
Also do I understand correctly that the other jets (do we call them intermediaries?) are pressed in?
What is the best way to tell which jets I have? Any tricks to removing the pressed in jets? 

I intend to run pods on this bike. I also intend to run it with an open header. It has a 4 into 1 and I don't plan on putting any muffler or can on it. (That may change later)
With that said what would be the best jet combination to run?

Any and all help/responses are appreciated.
Thanks
Sean

need to tell us what number is stamped on the end of your carbs. 
check the edge of the outer bowls and look for the carb model.

the size is usually stamped into the side or top of the jet.
if not, it might be aftermarket crap, and you'll have to guess and go up a 10, maybe a 15 from stock, as well as drop your needle clip position one notch.
the other PILOT jets are press in, and should be stamped as well. you'll need to go up to one or two sizes as well.

making mods like these when you dont know what you're starting with makes for a lot of guesswork, but it can be done.

OK, that makes sense. I'll have to check for the numbers on the side of the carbs. The bike/carb rack are down at the shop and I likely wont be there until Wednesday. Thanks for the response and I'll update the thread once I get those numbers.

I understand about the guesswork... Ideally I'll find the numbers but my corrected eyesight couldn't find any numbers on the jets the other day.
I'll attempt to get the numbers off of the main jets and the pilot jets.

Is the best way to extract the pressed in jets to work them out with a pair of pliers?

What is the best resource to purchase jets and general rebuild kits, gaskets, etc....?

The press in jets will pull straight out w pliers.
Check with Sirius consolidated for jets and carb parts..

Open headers are usually a bad move, they are too short to work properly
Using pods with open headers compounds the problem, bike may 'feel' fast but it's almost always because of rich/lean conditions when throttle is being opened

The carb is stamped: 42AAQA7
At least that's what my faulty eyes read.
