smaller tuning window ?

tuning and the performance that can be created by proper tuning are pretty much the same with all engines . the os does have a broader range that it will run , might not run well but will run . the novarossi engine(carbs) will work ok when carbs are way out of balance but perform awesome when the proper tune (tuning includes plugs , pipes and clutch also) is achieved. i have been running novarossi engines for a long time and i dont believe that the carbs are hard to tune myself . i can only try to explain the art of tuning over the pc , a little easier in person . you must first understand why the engine does what it does before you can tune it


i have tried os-2050 pipe on a few novarossi engines and thought they sucked . some people on here say they work well


i recommend the pipesets i recommend because i have founds them to work very very well on these engines .


if you have short track at home , i recommend a 3 port limited , they are excellent and only around 150-160$ , the toro nero is awesome but is suited for tracks where it can breathe . it has great bottom response yet its smooth , the 21-7fms is a great engine and has a 5 port novarossi feel with more in every dept. plus you get killer bearings .

hope this helps ,
