Tool to measure fuel mixture?

[degrom]

Is there a tool that I can use to measure the air/fuel mixture on different carburetors?

Using you spark plugs as way is useless to someone who does not know how to read it...

Smell is useless if you don't use the same make of fuel and don't know how to sniff it... LOL

Sound is for experts like on gone in 60 seconds. I can hear when it backfires but that is 2 turns to Rich!!!

Can an EGO tester be used to set mixture? (EGO=Exhaust Gas Oxygen tester.)

I saw a $30 EGO tester on JAyCAR's site. All it needs is a oxygen sensor like the ones used in fuel injection system.

All ideas and opinions are welcome.
Thanks.

A 4 or 5 gas exhaust gas analyser is the best - they start at around $8,000 for the home handyman level.You can't use them while riding either.An oxy sensor can be used but they have a limited range and won't tell you much.

Colortune ? Variable reports , I've never tried it myself.

LOL... Looks like I am cursed with expensive taste!!!

Will the local bike shop have one of those machines? Or what do they use?

(I think I will get the oxy sensor, it's a cheap indication to shorten trouble shooting...)

Thanks for the info.

I do not know mush about it. I know it works chemically.

Does it work with today's ever changing unleaded fuel's?

Thanks for the info.
Cheers.

You can make an adequate wide band gas analyser yourself, but it's pretty tricky. I think the guys on the diy-efi list sorted something out. Almost every oxygen sensor on regular cars is 'narrow' band. There was one particular model Honda car that had a wide band one from factory... they have the part number of it (About $300iirc) and the schematics on how to build the box to read it. Fun fun.

It also needs to be a heated oxy sensor,no way will you get a single wire one hot enough at the tail pipe.I often plug my DSO into the oxy sensor to see if it's running rich or lean,but that's all it tells me....rich or lean.

This could do the job

At US$349 you would want to use it more than once or twice

Or use it one and sell it to me for $250

Sensor used is a 5 wire (7 wire plug) NTK L1H1 or L2H2.
