How many of you have tried the 'trigger wheels'?? I have read about how they are supposed to give more advance and performance. Is that so? One of the vendors has them and they also recommend using higher octane gas. I have tried to make my 99 GL1500 ping by lugging it and it does not seem to want to ping. My 92 would rattle a little at very low rpm's when lugged, I am thinking if this wheel really helps out some it might be a good thing to have. I also pull a Aspen Classic Camper 2 up occasionally. Is the trigger wheel worth the extra cost??
