for watching My two newest video's out on my Channel

250 SX FMF Gnarly pipe sound test
Got back to 2strokes after having a test on my brothers kx 250.
Installed an FMF gnarly pipe and shorty silencer,really nice power
Sound is nice and not too loud,short clip at the end was filmed with a
phone and it makes the bike sound louder than it is.
Little Gizmo in 4 sec to 100 km/h Ftt Kreidler engine, made by Luc Foekema
This is a heavy tuned Kreidler 90cc engine Bore 53.7 mm stroke 39.7mm - 5
speed - Rotary valve - Ftt UltraSap ignition - Ftt calculated Exhaustpipe with - Max power 30hp at 14.000rpm,
with normal fuel 98 octan, no additions, beside lubrication 1:25
This test run was made Sept. 19, 2011 some days before te match.
In less than 4 sec tot 100 km/h
Topspeed in video is 106 km/h (at 150m about 130km/h)
Km/h in 4 gears: 53 - 67 - 92 - 106
5th gear not used, the track is to short.
The last Dutch Prostock record run over 150 meter was driven Sept, 2013
Time 6.66 sec, 0.097 sec reaction time. Which is 3.85 sec to 100km/h
Ftt calculations for combution chamber and Exhausts exactly dedecated to your setup, The
shortest and easiest way to realise the best performance possible of any
Just contact me or read: the comments of my Ftt calculations:
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
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
