Thank you for allowing me to join this forum !
i am based in Edinburgh Scotland
i have been building motorcycle race engines for 20years +
getting old now 🙈
so I decided recently that I will have a look into building/getting best from some 4stroke engines
I have also built myself a little dyno to measure output etc
not sure on rules if allowed to show a photo or video

thanks again

Thanks
i will have to work out how to post a video from iPad to here
this is my dyno , it is little different now , has new arm for data cables which it neater.
i used a dynomite Water brake and software ,
direct drive from crankshaft
I added
lambda ,airflow turbine ,fuel flow, inlet tract pressure,cylinder pressure and temp sensors for , ex gas temp ,oil temp,head temp under spark plug ,
I am really happy with it and getting consistent results and data

AT first I connected the engine to dyno using a little prop shaft .but was not happy with data consistency
I also tried chain drive but I found it worse
so now mounted directly on crankshaft 🏁
data from is now consistent and I am happy ,well for now 😊
As you guys all no these little engines make very little power so finding tiny changes/increases in results/data will help me
