I am currently saving for a new bike and do not want to invest anymore money than I need to in my current ride. However, I would like a little more out of my J1. I am ~250 ish and definately feel the stock spring is way to soft. I cannot find anywhere to order a x-firm spring. Do they exists for the J1. Also is it difficult to take the fork apart and change the spring. I would like to do the work myself if possible. Also would it help to change the oil in the fork to a heavier weight? Any help is greatly appreciated.
