Just got to set a goal for the year, and decide which is more is more important. Since the Jeep is already lifted, I would probably do the CAs, then the exhaust/tune and wide tire for the bike, then the gears for the jeep, then the paint job etc..
to be honest, since its this close to summer, thats a hard choice. Now that I think about it, I would probably just do one the way you want it, so you have the other to drive when its warm. I think I would do the bike now, since the Jeep is already lifted etc. and work on the jeep after the bikes done.
just my .02
