Jim:

Enklaste sättet att få en jämn fin effektkurva på en 2-takt motor är att montera ett passivt avgassystem (typ Simon 2″ system), men helst att cylindern är portad för det.
Men med ett passivt avgassystem går du att miste minst 10 hk som är möjligt med riktig pipa.
Men för att trimma in pipan till ett lägre varvtal, kan du förlänga ’bellyn’ eller förlänga headern.(kröken)
Körbarheten förbättra du dessutom med tändfördelaren 0231 144 004/JFU3.

Easiest way to get a nice smooth power curve on a 2-stroke is to mount a passive exhaust system(type Simon 2 ”system), but better if the cylinder is also prepared for it.
With a passive exhaust system, you lose about 10 hp in the top.
You can do to trim the expansion chamber to a low speed if you do to extend the ’bellyn’ or extend the header. (Elbow)
Driveability improve also with ignition distributor 0231 144 004/JFU3 with vacuum.

Why is impossible to swap Engine with someone that has an standard Sport/Monte Carlo Engine???

Easiest and cheapest way to get drivability on your car!

If it´s tuned up in wrong way or to much you will Always have this problem. Thats with any other exthaust system or distrubutor.

With a standard Engine it will still be a Little agressive and behave bad on Rpm´s under 2000. Tuned up Engines are most often only tuned for high Power = Low Rpm´s will really work bad. Less than 3500 or maybe 4000Rpm will the Engine not run good as you want.

So dont spend Money on an new exthaust system! Try to find some maniac that wants to rew above red on the tachometer instead!!

Talk to Chuck. He can probably help you. Or if you can wait until may I maybe can help you.
