The motor will run dreadfully lean with a stage 3 filter setup (the two parts you mention + snorkel removal). I'd say you might be OK for a very short period as a stop-gap without fitting a fuelling devise to richen things up, but I have to say I wouldn't recommend it. Sounds like your going on a longish trip too?

You could just about get away with snorkel removal and the stage 1 filter (cylindrical one) only and save the stage 3 cover for later. However, you aren't going to gain much benefit from fitting the filters anyway (unless you get additional fuel into the motor with a Kev mod/O2 controller). So all in all, IMO you're probably best ordering the parts from Kev, sticking with standard setup and fitting everything when you get back from your trip?
