Ive been reading about the air/fuel meters you can get and they state that theres no need for a rolling road to get the mix right. Is that right? Will this thing show me if its rich or lean and is there a optimum mix to aim for or does it depend on this that and the other?

They're a big help if you can't get to a rolling road - but they're no substitute if you want to get everything just right.

I have a JAW AFR meter, and it's been very useful in getting my bike carbs pretty close to right, but I will have to go to an expert eventually. However, they did help a huge amount when I needed to get from 'very wrong' to 'pretty close'.

Narrowband aren't *that* useful. Better than no information to go on but still limited use.

Wideband are very useful. They can't do timing tuning but they can sure do injection tuning. Quite a few ECUs now have self-mapping if you connect them to a wideband...

I still reckon for tuning bike carbs a £20 colortune is more than enough....

thanks guys. I will get a wideband one if I can find one ar the right price.
