ok guys, i know it has been discussed, but i have to ask.. i have a 392 cub motor on the bike, i do trail ride it, and drag it.. its a play bike.. i do have a trail shee that is strictly for trail riding.. i want to make the cub bike shift better and have been thinking about doing the 1-5 dunable overide... should i do it??? will it be durable??? i would say 30% trails, 20% open fields, and the rest just draging... someone school me a little better on the dunables... would i be better off interupting the ignition somehow when i shift?(for drag racing)
