November 18, 200916 yr I have a early Fantic 125. (TX250) fitted with what I beleive to be a Dansi Ignition system (its stamped into the flywheel anyway) There is a proximity switch (magic eye) fitted at 4.30 o'clock externally of the flywheel. It has two lines on it. One I guess would be the Fire mark (spark) and the other would be TDC. On the flywheel is an arrow which points approximatly (within a degree or so) to a boss (nodule / button / welded blob) on the perimiter of the flywheel which passes the proximity switch as it rotates. I's say this is the trigger. Being a logical chap, I'd hazard a guess that this must line up with the second mark as the piston reaches TDC. But it doesnt. Its about 30 degrees out - The bike does not run by the way, although it does - fire. Are my assumptions correct? Does the flywheel have a key? How do I adjust it? Do I need a special Fantic or Dansi flywheel puller? Anything else?
November 19, 200916 yr Hello, I ride a Fantic 125 TX250 (1977/78) and have an ownersmanual (in Italian). I can send you 2 pages by personal mail about the Flywheel. It shed some light about the marks. You will have to translate or read between the italian lines. My e-mail is info@@vormtekst.nl (remove 1x @) Kind regards.
November 19, 200916 yr Author and aries is a VERY nice 125.... I know! He emailed me some photo's today. Mine on the other hand is about as rough as is possible to achieve yet still be ridable. Aries. Thanks for the info, I removed the flywheel to find the key had sheared, hardly suprising as it was all loose. I set everything according to instuctions and it fired up first kick. Runs like a dream. many many thanks. RTM
