They are limited to the mods that can be done, due to the modular crank cylinder design in a one piece. I also watched a project wildthing on another site be built with nitrous.
I just built one out of a craftsman 4218 case and put a 38cc poulan crank,carb,muffler non-epa stuff inside it in 2.5 hours one day, very easy to work on, even changed the throttle routing to run a different carb from throttle on different side.
You can do muffler, carb, exhaust and intake port work pretty easy on them. But thats where it ends for me with the one piece crank cylinder design topends.
My Poulan project saw 38cc Smoked my Stihl project saw 41cc in timed cuts, both using 3/8LP chain and 16" bar. Hence the stihl has been sold.
