Is anybody selling an air fuel ratio kit with sensor to fit a 1995 Monster 600 or can you suggest any recommendations of where I can buy one from ? I have found several on the market but not sure which one is suitable for my bike and a lot of them seem only suitable for cars.
AFR kit for a 1995 M600
- Thread starter Foggy
- Start date
No experience of carbie Monsters but I'm sure that your's won't have an access point in the headers for a lambda probe so you could discount anything that uses one. Then I think you need to start ringing suppliers of what's left and ask if their product is suitable. Might be cheaper in the long run to book a dyno run with someone, they should include the data you want as part of the report. Why do you want one by the way?
Stop press - I was told today that the carbies DID have lambda ports in the headers - presumably for factory set-up?

OK thanks, yeah it looks like there is a bung in the pipe which I assume is for the sensor.

Why only suitable for cars ? AFR is the same on any engine whether its petrol, Deisel, LPG, Methol it matters not
Admitedly the cheap ones tend to be sold with a 52mm gauge which might lend itself to a car more easily
however assuming all you want to do is measure as no way to adjust AFR when riding carby bike so probably better off with a decent probe style analyser, make sure it is wideband
It won't be cheap - as all of the lower priced ones are just a narrowband controller with a gauge interface pretending to be wideband
I would still question the need for such kit as can still only ever have it spot on for one condition on a carb motor which will change with atmospheric conditions and therefor be wrong 20 minutes later, however if like a few of us you just have to have a funky new tool --- this is the one I'd recomend as a starter
It will do both probe and fixed lamda

The only reason I say suitable for cars is because that's what the sellers have been telling me because they think I am going to be riding around with it connected all the time. I agree with you it doesn't really matter but the main problem I have had is the thread on the sensor provided with the kits... it is M18 x 1.5 whereas the OEM bung on my bike is 1/8 BSP so struggling to find an appropriate reducer. I realise the kits can be supplied with bungs to weld on but seems a bit unnecessary considering I have one fitted already.
Thanks for the recommendation though, I will take a look.

Ah OK makes sense, the issue remains that the bung on your M600 was used for an O2 sensor what first run at the factory to check rich / lean and thats it !
You can get easily 1/8 BSP / NPT o2 sensors but they will not give you anywhere near the accuracy that an AFR sensor provides
Most if not all wideband lambda's use M18 so roughly 10mm bigger than the hole you have !! so as said without welding your only simple option is a probe
