Greetings from Holland

Indlægaf Tombo » søn 26. okt 2008 20:13

Hi, i would like to introduce myself here.
First of all, my name is Tom, i'm 22 years old and i study Automotive Engineering (@ bachelor level, i've already got my bachelor degree mechanical engineering). One of my hobby's is my FS1. I've bought my fizzy when i was 17 (before that, i had a Kreidler, stupid german piece of junk :mrgreen:). I've restored it completly with my dad a couple of years ago.
Engine setup:
-43mm FS1 cilinder, tuned by myself (not to extreme)
-16mm mikuni
-reed valve inlet with carbon reed's (i also have a rotating valve engine, but reed valve runs better, wider powerband etc)
-Homoet exhaust
-13/39 gear ratio
Top speed: 90 km/h on my GPS (with the best possible conditions), but normally it runs 85 km/h quite easily.
I'm planning to buy a 5-speed engine this winter, and to fix a Selettra inner-rotor ignition (already got it, and modified it to fix it on a fizzy-engine) from a Rotax racing kart. Also I think i'm getting my cylinder bored up to 43,5mm with a new piston (piston clearance is to big now... the compression can be better).
Here are some pictures:

Also i like to experiment with tuning, but sometimes it goes wrong, and you get something like this :lol:

I've milled down the cilinderhead too far, as a result i've had too much compression and the engine started to detonate... :D

Work in progres...

Modified Selettra ignition:

I also restored my sisters boyfriend FS1 last year (see pictures). It runs about 85 km/h with a 43mm FS1 cilinder, 16mm and also Homoet exhaust.

Hi Tom,
Nice looking bike you have there - i specially like the colour, and fun for us to see the difference on the models from one country to another...

Interesting project with that ignition. I am looking forward to hear more about it :!: Is it only ignition, or does it include 6 or 12 volts for light in that unit :?:
I also have an idea about making my tuned FS1 "electronic", but until now my plans was more in the direction of f.ex. a Jog ignition :mrgreen:

Hi Tom
First of all welcome to this forum
Very interesting project. Hope you can give us some good ideas and inspiration.
I am also considering how to modifying the engine ignition and are looking forward to see some more.

Good luck :wink:

Tnx for all the reply's!
I forgot to mention that me and a friend of mine made a dutch fs1 forum (http://www.fs1forum.com).

@Morten, that's true. I've registred a long time ago, but i forgot to introduce myself. Yesterday I stumbled upon this site, and i thought it was time to introduce myself.
Funny thing is that most of the time i can understand what most of the topics are about, because Danish looks a bit like Dutch. It also looks al bit like Frisian (Fryslân) :mrgreen:

This is only the ignition unit, no lights or whatever. I've tried it a couple of times, but i dont always get a spark. Sometimes the sparkplug sparks like hell, but the other time it doesn't do anything... I'm still trying to figure out what's wrong.
