My races.

My races.

In 2013 we were enough riders to form a national championship and that gave me a chance
to try out racing for points for the first time! As my supercharged Honda didn´t
comply with current regulations, I had to build a racebike for the championships.
Three races in all - at Ring Djursland, Padborg Park and Jyllandsringen.
Having saved the engine from my first Kreidler build-up:
ET Kreidler build- up.,
a new chassis were prepared and finished just days before the first race.
First race saw these competitors:

And sundays....
Second round of the 2013 Danish 50cc classic championship
took place at Padborg Park. Found the crank to be the culprit
of the vibration felt at last outing - and a fresh crankshaft
were installed on route to Padborg, in the well- equipped
shop of:

Arriving at the track first thing was to install the rejuvenated
engine, and finished that just before the Tech- inspection turned up!!!
Friendly tech- inspector shows how its done right,
and then gave me a lesson on how to bring the right tools!
I was not really sure about the authenticity of these
tech- inspectors, having seen the other tools in their
tool- basket? Was that a chainsaw?
Competition was fierce as the guys from Classic 50 Eurocup
participated in this race too. They had their own battle
going on, and we locals could only watch and learn.
Third and final round at Jyllandsringen.

My Kreidler engine lost all traction due to a cracked
primary- pinion.
Sponsor ( saved the day once again!
I must say that the final race- weekend of the season
was a real cliffhanger! First outing was a qualifying heat
for saturdays race - 3/4 lap out engine cracked the primary
gear - bummer! No spares - nothing! Chose to ring a friend
instead of a Psychiatrist- he maybe had a dryclutch mounted
on an engine, and maybe it had a straight- cut primary? But
he was out of town that weekend. He called back later with
good news - his son had offered to pick up the engine and
bring it to the track - bad news was that he was busy shop-
ping with the miss´es. Worst hours of my life listening to
my competitors whirling round the track lap after lap
during the second qualifying session.
The engine finally arrived and upon diassembly it was
revealed that it was in fact a straight cut primary - but
of a different ratio! Did my best to adapt the whole dry-
clutch unit to my engine and it did fit - only a very tight
fit - like no tolerance at all! Late in the afternoon now
and saturdays race were only minutes away - so I had to
decide - leathers on - go for broke! Dead last in the
lineup and a very bad start on an unknown track - managed
to finish in third place. Engine backfired through the carb
at exit of corners making more downshifts necessary - what
a mess!
Before that heat I was only a single point behind, and now

A long wait for sundays race - not daring to go out at the
morning warm- up. If I hurt those borrowed pieces I was
really in trouble!
Sundays race should have been a wet one, but for some
reason it suddenly stopped raining and a dry track waited
for us - bad start again but being highly motivated by
the fact that in saturdays race, my lap- times, all problems
aside, had been three seconds faster than everyone else :o)
Now familliar with the track I was plowing through the field
and in third lap I spotted the points- leader - it took a
whole lap to pass him but I did - only to discover that yet
another were ahead. Some one and half lap later he was
passed and I finished the race almost half a lap before him!
Felt really dizzy when they ordered me to the top of the
podium - the ride of my life :o)
The bike had produced some slight drifts - nothing hazardous
- I promise!


As the first championship- race of the 2014 season came closer
I had to leave the Puch- project:
ET Puch build- up.
and concentrate on the Kreidler. The to-do list involved more
than just a dust- off as I intended to make the chassis more
agile in the bends. Axle- axle length were reduced some 35mm
by shortening rear swingarm and raising steering angle a few
degrees. Engine had produced some nasty cut- outs during last
season so a thorough revision were needed. Also a new primary-
drive and clutch from
What followed was a very wet race- weekend at Ring Djursland.
Machines present at the season opener:

The dreaded and VERY annoying cut-outs haunted me once more:

Video of sundays Classic 50cc race.

I did NOT find a solution to the problem before next session
at Padborg Park raceway. However, learning that several new
racebikes will join our championship later this season sort
of cheared me up - just take a look at these:
The Padborg races were actually three different championship
races combined! Second round of the danish national 50cc
championship were joined by the 50cc Eurocup- boys and the
new 50cc FreeTech class.

Third and final round of the 2014 50cc classic roadracing championship
took place at Jyllandsringen. At this event called the
Classic TT, a record- big turn-up of danish 50cc racers
showed up! Listed by the numbers:
During the engine- preps prior to this race, I noticed a chip
in the Nikasil layer of my Kreidlers cylinder!
No time left to get the barrel re-Nikasil´ed so I
tried to smooth the sharp edges with emmerycloth.
And in went a nice rounded (used) pistonring!
With this leaking barrel I had to collect enough
points to secure the championship..............

Went to the season opener with a friend. Peter being a rookie
soon became so familiar with the racebike on loan,
that he ended up as a podium finisher! The ex-
Honda, now Kreidler- engined racebike were
strong all through the weekend.

Had the frame back in the jig and - everything checked out okay :o)
I have to stay on the wheels from now on!!!

Participated in the Roskilde Ring jubilee races and
Copenhagen Historic Grand Prix doing motorcycle demo- runs

Second round of the championship races took place
on the lovely RingDjursland track.
A VERY wet weekend were ahead with non- stop rain
friday through saturday, and even well into sunday!
Saturdays race brought a new experience - with that
much water on track, my discbrake combo rendered
useless! Brake- lever and pedal were rock- hard -
I couldn´t even block the rearwheel with that 210mm
disc, which on a dry track normally demands a very
delicate touch?
Only way to slow that damn thing down were to use
the little engine braking a twostroke offers - bummer!
Qualified on pole but ended up in third place.

Saturdays race- recording.

Sundays race were much better, but I was rewarded
with a 20sec penalty due to a stupid jump- start!
Only chance of winning were to finish twenty
seconds ahead, but I only managed to reel- in
some fifteen seconds and was relocated to third
This was later changed to a second place finish
due to another riders unfortunate disqualification?

Third and final round took place at Jyllandsringen.
As the Classic-TT event were both an invitational
race and the final round of the UEM european cham-
pionship, a few foreigners turned up :o)

Visited in august the racetrack Sviestad near Linköping to test my just finished Puch racebike.
Following racers turned up:

Sviestad 2017 - heat 1.


Returning to championship- racing after a few years absence.
Missed the season opener due to not having finished the new Sachs- engined DeJager racebike.
Second race were held at JyllandsRingen where a lot of problems kept me out of the races.
Rushing a project like this and you will end up having to dial-in everything out on the tracks.....
My first visit to the Scandinavian Raceway Anderstorp TT -
a real GrandPrix track with a 1,2km straight.
A new experience to establish a final ratio for that one.
Final ratio.
TGM Some new very interesting racebikes turned up for this event:
The TGM engined Pasotti of Rikard Käll(se) - just beautiful! Tomos of Karoly Kenyeres, Serbia - perfect!
Winner: Søren Lemming - Kreidler.
Another disappointing result from the not dialed-in Sachs racebike!
However, moral got boosted right back up when one of my engines, in the capable
hands of Søren Lemming, did win the sundays race including a spectacular lap of just 2:15!
Video from the end of season race on a wet RingDjursland track.
A slipping clutch hampered engines full potential. Looking forward to 2019 season.

New for 2019 was the introduction of a beginner´s class - rather unofficial
- but effective in getting "oldies" as well as newcomers on track.
A Cup for fairingless, piston- ported machines - that ofcourse fitted into
our general 50cc classic rules.
Examples of machines eligible for the MopedSpeed Cup below:
The 2019 MopedSpeed Cup.
Cup Kreidler of Per Bundgaard Sørensen. Puch - Daniel Baunsgaard.
Simson S51 - Eva Thagaard Nørager. Cup Kreidler of Lars Mortensen.

Anderstorp 2019 - heat 1.

My second visit to the Swedish GP track and eager to try out my Anderstorp-special fairing!
That fairing really was an improvement!
Did not bring a secondary ratio to match the new topspeed,
and had to sit right up for half the straight to reduce overrevs.
Were lucky to finish in first place.

Heat 2 went okay - until breaking two cylinderheadstuds....

Ring Djursland 2019 - heat 1.

Primary engine pulled okay for this race - reward was a second place finish.
Again a broken cylinderheadstud revealed itself upon inspection!

Ring Djursland 2019 - heat 2.

Spare engine went in for the last race of the season.
A certain degree of pre- ignition caused a leaking headgasket.
O- ring was burned to a crisp - not good for performance!

2020 - The "Corona" season

June 28 at Jyllandsringen: Couldn´t wait to test the cylinderstuds made of titanium!
As I didn´t bring my spare engine for this sundays races - last years problem could be an issue.
As it turned out cylinder stayed in place and engine performed okay!
