Are these actual upgrade parts??

[Carl Walichnowski]

Ok I purchased or plan to purchase these parts, does anyone know if these parts are worth getting? I'm not trying to spend too much on upgrade parts so if anyone has suggestions on if these will improve performance or if they know where I can get good parts then please share.

NO not really the carb is basicly the same size and tunability The pipe is just crap! And the head has very little surface area to wick away heat!f For a head the combustion chamber design and volume are what make it gain performance IMO this head pictured here is the best all around from MZ Miami they also carry the mx style pipe! to replace the carb for more tunability there are many good ones out there but they are not cheap!If your not going crazy with internal mods like port timings and volumes the stock nt actualy works quite well!
