I'm sure we all reach a point where we have to make that decision. It's kind of strange that when we have put all the work & add ons to your Trike you start to think its the right time to trade it in. Recently I was at that point, but after seeing what they offer on the trade & knowing what I had into the Trike I opted to keep my Trike and do some upgrading. Since I had already done the "Big Bore" route I decided on a set of high performance heads which I would have to have diamond cut to match my cylinders, high compression pistons, push rods, a set of cams, & a bunch of other goodies, which would also include new oil cooler & temp. guage. Since I was this far into the engine I replaced anything that had any sign of wear, I feel that I now have my Trike all freshened up for the future. It's strange but I've been at this point many times before, you get to a certain time with your snowmobile,bike,car, where you have done all this upgrades & decide it's time to trade & then you start all over again. This time I decided with all the upgrades I would have to do with a new Trike, I would keep what I had & go from there. Now I'm looking forward to some great rides...Tis
