Removal of silencer on 582 rotax


Recommended Posts

Hi I own a 582 rotax on an airborne trike and wondering what changes and what is involved in taking the silencer off to get better fuel consumption. Thanks.

Never heard of removing a tuned exhaust to get better fuel consumption, 2-strokes by nature are thirsty. I did fit an basic untuned exhaust system to a Robin 440 2-stroke once, to prove there was actually something wrong with the tuned exhaust a mate made for it (long story but the pipe plan dimensions were incorrectly translated)

 

It was LOUD, UGLY and tellingly, p*ss poor fuel consumption but it did run consistantly, the tuned exhaust actually restricted power and eventually melted a piston.

 

Is everything properly tuned.. ignition timed correctly, air filters clean/new, plugs good colour, jet sizes correct?

 

I'd start on that side of the engine :)

 

Cheers

The manual for my Aircreation trike says different jets in the carbs if removing the silencer.

 

But doesn't specify what jets to use.
