well this is my 3rd update on this problem. i have a 1992 tomos targa w/ a bi-turbo and the engine rebuilt to my standards. a couple of weeks ago i was riding and all of a sudden it died. so i opened the maggie cover and one coil was tore up. i replaced it and then it ran like total shit!.so i found another coil was screwed so i went back to the shop and this item i got a new condensor new poins and the new coil. put all these in the bike and....... vrooom. it started with half a kick. so i went for a ride and checked all the lights etc. all perfect! now my acceleration is better and i hit a higher top speed. boy i am glad it runs
