ESE's works engine tuner

here is my 50 , rg50 A/F reading , running a nsr 28mm carb , runs rich to lean then a slop to rich and lean on over revengine struggles to pull past 8- 8.5 rpm as seems to rich on A/F , but gets up and go's past that

Water cooled head? some other interesting looking motors in the background.



Assuming the AF ratio of all the air passing through the engine is 12:1 or so over the full rpm range then this graph shows a neat correlation of the trapping efficiency and torque curve. Very interesting.

The sensor is measuring excess oxygen, not mixture, maybe its not so much the jetting being wrong as the airflow being wrong

Yes excess oxygen in the AF that was not trapped and burnt.

The new Beast is ready for a test run on the Dyno, maybe get to it Tuesday night.

may need a new name now (-; looks real good

was going to try reads first but can't fine any , gave my spring steel ones to help my mate out now want to try them dam it, think some with more tenison may help . May run some cut down reeds on top of reeds to change pivet point for more tenison

Thanks. Maybe I could call it Queen Anne'S Revenge. That was Black Beards ship.

Are you looking for standard RG50 reads? Could find you some if it would help.

[TZ350]

Yes we could call it Mr Bigglesworth, the bike is crazy enough.

[Frits Overmars]

The new Beast is ready.. .

I like the double footrests and the long seat. Are you guys doing much pillion racing over there?

The round cast head looks like a Chris Ziffle creation.

I built 3 like that. Ziffles one is at the old mans .going to get these classic buckets going .maybe could be a fun class if run on 17s
