I have a v-tec mod on my bike and i messed with the timing adjustment and now I feel like its not right no madder where I set it.It has a dial from 1 to 10 I think it was somwhere between 2 and 3 but not real sure . I am not even sure how the thing works I would think you would have to plug a computer into it or somthing but there is no plug to do so and I sure I would have to have the program for it . Ive tring finding the answers on my own ,because I hate asking dumb questions but....oh ya I have 2004 sportster custom 1200
