Hi,
my name is Tom and Pork Pie told my if I had a question about speed..Bonneville..classes etc. I posted here.
My dream:
Once time in my live to had a great ride on the saltflat at Bonneville!!
My hobby:
Drive fast with 2 or 4 wheels..on the street or race-track
My Motto:
Have fun in the free time
So I hope that I was able to do all 3 altogether. 8-)
I/we(K3-Team) want to start in the smallest bike class,the 50cc.
Now the question:
What class can I ride with this "bike":
(http://hometown.aol.de/boxerhahaha/images/flory31.jpg)
It`s a KREIDLER FLORY
50cc,1,5hp,1976,15,5mp/h speed at law.
Don`t laugh... we call it MoFa (MotorFahrrad/motor-bicycle) in Germany (drive till 15 years old):-D
So we want to drive the fastes MoFa....
Must we start in the class "P"??
What things we can/must change to start in "M" ?
Must we change the breaks?Fork?Damper`s?
We are able to modify the orig.cyl./motor and drive with the orig. 3.gear motor.
Can we take off the pedals and made a gearing with foot instead with hand?
Change the seat?handlebar?take off the lights?
Sorry for that many questions,but first we must know what kind of bike we must built!
Or we take this 50cc "bike" for had fun with speed?
(http://www.moto-ri.de/bilder/Kreidler-Florett-RS-1978.jpg)
Kreidler Florett RS,50cc,6,8hp,~53mp/h at built,5.gear box
What class?etc....
Hope we have many helping hands here.
Greetings from the cold Germany
Tom
ps:Sorry..if this the wrong topic,please take this to the right on..thanks :-D

Welcome.....the first thing we all need to know
SCTA/BNI or BUB event?????
-
Any bike that is "as produced by the manufacturer" would run in production class. Any modifications must be out of view (motor internals, muffler gutting, etc). If you want to run modified, just change something externally and it is no longer production.
Get a rule book as soon as they are available
If running Bub, the rules are online.
Welcome and good luck.
-
Are they 2 stroke or 4? Just curious, got nothing to do with your question.
-
Kriedlers are two-strokes. They cann be made to go very fast. VanVeen made (or perhaps still makes) some incredibly fast 50cc machines. I spotted this in a mag a while back. Illegal for SCTA but legal over there. 50cc = 140mph. (http://)(http://img517.imageshack.us/img517/1695/img118nm8.jpg) (http://imageshack.us)

Welcome.....the first thing we all need to know
SCTA/BNI or BUB event?????
Thanks for welcome..
At the 2 h call with pork pie I don`t know yet wich one?
SCTA...ich write some mails with Ellen....
BUB...I see the rules and records...
BNI...I know only the word.
Ok..for us it is the best to had a run after September...
We want to change some parts of the MoFa...tune the motor..we want to drive fast.
So I think M-AG or M-AF...
We thinking about...without partial stremlining or with.
We also had a option of class A or APS.
But we had a dream..so we want to made the first "bike" (MoFa) very fast...but the look must be orig.
I like streamlining/streamliner...they are very fast...but looks like a rocket..not a bike.
What do you think wich class we can drive with the first bike I post?Without some heavy parts..tuning...other seat..handlebar..
A other question..wich class was this bike:
(http://my.photodump.com/PMS/P7130099-T.jpg) (http://www.photodump.com/PMS/P7130099.html)
It`s the same motor as in the MoFa..without padels...and a frame from a HONDA RS125.
Hope you can help us to find the right class...is not easy to find this for us..many rules...etc.
We like Kreidler since I was 15 years old..it was my first " bike"..take many trips with this small bike...but always not legal (who can drive only 15mp/h?? :?).
Kreidler motors are very god for this time..I think the best on..made records on the saltflate..fastest 50cc streamliner..many records on the tracks.
We know,that today there are better motors,with watercoold...6.gears...but we had a dream!!
In Germany they are not realy many MoFas on the road,only some scooters with a speed of 15mp/h,but ths is not a Mofa in our eyes..the bike must have pedals,then it`s a MoFa!
Thanks for your post.

I forgot to say welome. The 50cc producion record is 75mph so the moped would be out if its depth for a record attempt. The M and A records are in the mid to high 80s. The Kriedler RS would be a much better bet. Especially if you could locate an air cooled VanVeen barrel and a decent carb and pipe. You could run in modified and have a chance at a record. Many years ago I used to race a Kriedler and it was a lot of fun and a fast little bike. Good luck.

nice pic...is that you on the KREIDLER?
(http://imgcash1.imageshack.us/Himg137/scaled.php?)
We know about Van Veen bikes..very fast at the track...
One time in the year (beginning of September) we drive with the HONDA/KREIDLER a 8 hours long distance race.
We must use the motor from the MoFa...only without pedals..must use the orig. cyl. and head..carb and pipe are free...but only 3 gears like the orig.!
You know about the rpm of 50cc...and only 3.gears...max.rpm at 15-16.000...1.gera very long to start.

Hi Tom,
as you see....it works....
By the way....Ellen is USFRA.....and, sorry, I forgot to tell you - the BNI is the organizer of the Speedweek in August and World Final in October - they manage this two meets, together with the SCTA.
Also, the P class said "Any modifications must be out of view (motor internals...." in other words, so as I said you on the phone...inside it could be modified.....means hot pistons....and more.
I'm sure one of our bike inspector on the landracing can tell Tom where the limit is for the internal modification......
So, hello Inspector.....please gave Tom the support in this way....I got the rule book here....and Tom lives only 20 miles away from my place....when he knows which class he can go, we will go through the rule book and than he can decide what he will run at the white dyno.....
.....to this what I heard from Tom.....I can say he is in speed....so as we......and every support is appreciate.....
See ya
-
Tom, your description of the orange bike, Honda chassis, MoFa motor makes it an APS bike. M and MPS bikes must have matching motors and frames. If you come in September you can run at Bub and World of Speed (Ellen) and run both sets of records, WOS runs against BNI records, Bub runs FIM and AMA records.

Here comes a shamless plug.............................
Bakker Framebouw in the Netherlands builds
replica Kreidler roadrace frames............in fact a couple of years ago they made a complete Kreidler
engine replica using CNC.........Europe loves the "little" bikes......................................................
-
Hey Bob, I've been a sucker for Kriedlers for years now. Any photos of the frame you make or the Kriedler you built? This was mine from around 1978. (http://)(http://img137.imageshack.us/img137/3627/img013bk8.jpg)

I am presently at our other home in Arizona
(Wrighwood CA. to cold right now for this old man) I will check with Nico for a picture of the frame and/or complete bike (Kreidler).............
At the end of March I will be off to Germany for a trade-show........may get the pictures then.........
Next to sidecars, I just "love" the little bikes.....
got a 125c.c. Rotax powered machine for sale....
in fact 2 of them!!!!!!!!!!!!.............................................

Thanks Pork for helping hand... 8-)
Uff..so many...USFAR..BNI..SCTA...so only what I can say now ist that we want to start earliest in October or May.
About clases:
APS was very interresting,because of the partial stremlining=speed...we had also a full cover panel in front fot the HONDA RS 125 frame...then it look likes very fast! :-D
but..MPS..we can run with the first "bike"?..with the modif. orig.motor?
Class P....also..our motor was looklike the motor as the MoFa...thats the rules at the Mofa 8h race..all must be the same as the motor from the Mofa had...but we use a reso-pipe..a bigger carb..and now we use a rotary slide intake insted inteke over the cyl....are we in class P with this motor?
We are able to change the cyl. and carb-intake..no problem...but using a reso-pipe must have...
so..hope you have a little patience with me an my DREAM.

Tom
ps:Now we are on the way to a short trip to SUEDTIROL(Itay)..MERAN...hope there is a nice wheater.... 8-)

The pipe will take you out of production class, the rule says it must be a stock apearing exhaust system and looking at the end of the muffler the exit orfice must be the same diameter as from the factory.(paraphrased not word for word)
-
Production or PPartial--They get really "picky" about "STOCK APPEARANCE"--even to rake and ride height---been there--been "DONE" :-o
-
Interesting.......If Tom were to enter the P (production) class at SCTA/BNI or WOS, he better bring lots of pictures of a "stock"
Kreidler.............I don't think the Tech. inspectors
have inspected a Kreidler in resent times............
At the BUB....."FIM Charlie" might be helpfull.......

Exactly what the rulebook says, bring proof you are production.

We are back...we had a nice wheater in Suedtirol..nice roads..drive thrue SCHWEITZ..AUSTRIA..Italy...with a FORD FOKUS ST(220hp)..nice on the road! :-D
ok..thanks a lot for the many news!!
I think the class P ist not realy the class we want to drive...with the MoFa-motor we maybe made a speed of 40-45mp/h..with this P-rules..the motor was at a few points for max. speed of 15,5mp/h made at law..extra small carb(10mm)..cyl. with only 1,5hp..a pipe with very small orfice... :-(
Than the M or MPS...A or APS...
Pic`s from the stock parts and bikes are no problem....
But what did the Inspectors say about the frame...you know built for the high speed of 15,5mp/h!! :-D
OK..I tested on my one...1982...with~53mp/h..with no hands on the handlebar..no problem with the stock frame and wheels..brakes..shocks.
Must the frame look like the stock in M or A classes?
Greetings from Germany
Tom
When I take of this parts of the MoFa...wich class is that?
M or A ?
ps:
-

M or A ?
ok..in both classes we may remove the fenders.
next...I read,that only one brake must be on function..is that right?only the back break?
It is better to have only one brake??why?
-
hi tom,
you must be the guy from ludwigsburg ?
(as i heard from porky pie)
nice flory btw.
i´m mark from stuttgart and try to race 20089 as well.
we should meet and exchange some infos.
cheers,
mark

Hello Mark,
yes I am from Ludwigsburg..near Kornwestheim..the "home" of KREIDLER! :-D
Send me a pn and we meet us or tel.,no problem.
Hope we can start in 2008..but I think with test the MoFa etc. we start better in 2009... :roll:
To many questions about the rules...
With the MoFa we made us a dream,but the rules don`t made a differnce about MoFa..Moped..etc..only 50cc!!
In class P with the MoFa we had now chance.....you know the Germany restriction on the MoFa-motors :|
Maybe it`s better to use a Florett frame...than use the 4.or 5. gear motor...based on the 2,9 (small cyl.) or 6,8 hp motor.

tom
ps:one question about the gripp on the white dyno (I like taht name! :-D).
Pork Pie told me we had about 10% less speed at the saltflat than on the road...what trick do you made??
Less pressure at the tires??Special tires?
-
A lot of high-powered vehicles lose speed by spinning the tires. I don't think your 50cc motorcycle will have this problem.
Pork may have been referring to the horsepower loses because of the high altitude -- almost one mile above sea level.

.....................Pork Pie told me we had about 10% less speed at the saltflat than on the road...what trick do you made??..........
Bring some sea level air with you. The salt is about 1370 meters above sea level.

Thats right...Pork told my about the high altitude..I forgot to write...
So I made better test in higher area at home to have a better setup-start at the white dyno...
we had some nice roads in ~1200 m...
ok..so whats about the pressure in the tires at the 50cc bikes when I had no spinning ??
About classes:
Yesterday I tel. with Pork....the class P are nor realy good for us with the MoFa.
So better try A or M class...
Tom
-
Welcome to LSR,
Sum
Thanks.. :-)
..next week at 5 March we spend our holidays in PERU...drive some high roads (max.4800m!!)..swim in the beach>summer!
We had a little stop-over in Dallas (5.March at 2.30pm) and take off at 6 pm to Miami (9.30 pm)..hope to take off to PERU at 12pm..or we must stay one night in Miami.
At 28.March we are back again and we start to build the high-speed-MoFa! :-D
Tom
-
OK..no I am still here...need more informations from you... :-D
In class M or A
Question:
-The orig. Mofa-motor had 3.gears...it`s alowed to change the gearbox?Outside it`s the same..inside we can made a 4.or 5. gearbox..
-The MoFa had a handgear and have pedals like a bicycle...shoud we change into a footgearing without pedals?
We know..it was a lot easier to put the Florett frame/bike...but we like the challenge..had a dream. :evil:
Hope we had enough rules informations till end of March,so we can start to built a fast Mofa.
Then we can post some pics from the MoFa,and we hope you will help us to find a class or to change some parts from the MoFa that we are able to start end of the year....or 2009.

I know the rules from the diferent org. was not the same,but some of them are similar..
It`s the time when the event starts...we only can start end of september or May.
At the begining of September we had our 8h -MoFa-endurance...so no time for the speed MoFa! :|
Thanks for the records in classes and the luck. :-)
I see,some of the records are 30 years old!!wow...hope we are able to beat them...
But Fuel and GAS...Fuel ist the normal patrol and Gas are a mix from alcohol etc.?
We even use normal petrol from the station...about 98-100 octan.
In class MPS..we can use any covering from a bike?? :?

I saw a pic on your hp....

.... a scooter! :-o
But I see no class for a scooter. :?
Tom
-
The Bub Meet has a scooter class, AMA / FIM rules :-D
The OLD AMA records were not used for a lot of years, revived by Bub. Old records often mean no one is running there...
-
Gas class....normal pump petrol
Fuel class...anything else then pump petrol....
like Metanol enc.
MPS class...roadrace type fairings....(no Dustbin type)
Scooter, like in your picture, running over 100mph.....(standing up on the scooter)

realy??!wow..I like the old Vespa...in my avatar I drive with my 1966 Vespa on the Nürburgring (Grand-Prix-race-track-about 5km long).
The speed on the long flat road (800m) from the track was about 89-89,5mp/h.
2008 in May I want to drive about more than 93mp/h...
But it`s no race-motor in it..just my every day scooter...drive to work..but in a PX 1983 chassie.
Hope end of the year ,I can start again with a new motor projekt and drive 99-100mp/h with a other frame
I must see the rules in BUB for scooters...also in cc??
Maybee a project 2010?? :-D
I like this small and old vehicles.... :evil:

Thanks about that info.
OK..I think we try the gas class,because we never try methanol or something else bevore...
Never change a runing system... :-D
what are roadrace typs meen??or Dustbin?
We had a fairing from a production racer..HONDA RS125...is taht ok?
The scooter is like a scate-board??
awsome!! :-o
what cc had the scooter on this pic?
Tom

Roadrace fairing...like your RS Honda................
Dustbin fairing....like on roadracing sidecars.........

Roadrace fairing...like your RS Honda................
Dustbin fairing....like on roadracing sidecars.........
Great!Thanks! :-)
So we are able to start in A or M...and APS or MPS..and gas
OK...time to time we find our class with the MoFa! 8-)
Maybe we can start in 2 classes?? A and APS or M and MPS?
Is there enaugh time between the runs to fit the fearing on?
