Profile:
I started racing in 1964. Computers were still not there. I did hardly no calculation. With the advent of the computer everything has changed and complicated calculations are no problem any more. All old historical notes were struggling. In the past 15 years I got a number of programs. Beside I did developed many programs myself in Excel. It was my profession to do so for my employer for many years.
In 2003 also began making calculations for third parties. Not everything, but a lot can be calculated very accurately for any twostroke engine. For instance the exhaustpipe can be calculated in almost exactly the correct speed for which the setup and cylinder is optimal. Even by a large kart engines manufacturer (TM) was found to be not entirely correct. With a new calculated combustion chamber and exhaustpipe it was far better then before.
This is also partly due to the information I got from Jan Thiel and was freely available after retiring from Aprilia racing end 2007.
Also the UltraSap ignition developed by my son Raimond was a very important part. The combustion and power are strongly influenced. Read about this subject my note on Facebook

Zweiakttuning in Vollendung! Klasse.

[@drood78]

Ongelofelijk wat je uit zo'n machine aan power kunt persen, heerlijk gewoon. Het geluid alleen al geeft me kippevel. je hebt er een subscriber bij ;)

[@hdehaas78]

Ja dat kan luc wel dat is een gegeven feit. Er is niemand die hem eruit rijd met geen ene snelle brommer

[@hdehaas78]

Prachtig om te zien, dat trekt echt hard, u hebt denk ik geen originele vertanding in de versnelling bak

[@50ccRacing]

De eerste en 2e versnelling zijn iets langer dan standaard, 3-4-5 zijn wel standaard

[@50ccRacing]

Dat mag dan ook wel, als je in 1964 ermee begonnen bent. En in 2003 begonnen ben om ook voor derden berekeningen te leveren. Niet alles, maar wel heel veel kan echt berekend worden. Ook het door mijn zoon ontwikkelde UltraSap ontsteking is daarbij zeer positief. De verbranding en het vermogen wordt hierdoor sterk beïnvloed.

LODZ WHATS ENGINE THIS? AND WHAT CONCEPT?

[@Windsurf-wingfoil]

gaaf man! je bent sneller dan ik met mn surfplabk, hahahaha

[@50ccRacing]

Dank je Ronald, jouw surfvideo's zijn minstens zo spectaculair. Als ik ze zie dan krijg ik er altijd weer zin in.

[@MrAdpran]

Seem like you always ride same drag bike. But is that really same bike, or actually few different bikes with same model and same color?. Greeting from Indonesia, Luc. :)

[@50ccRacing]

All runs made after 2006 are made with the second built one. The full story from the beginning: facebook.com/notes/luc-foekema/eerste-nederlandse-sprinter-1967-interview-2007/3021388752810
