After taking up space for a year or so I finally got to fly my Firefly today.

A short trip around the block but was much fun for my first flight since purchasing it a year ago. Actually in Wisconsin...KRNH

Weedhoppers and weight shift Eipers don't carry temp gauges. When I got my Firefly running i added the EIS system. While on this little hop I couldn't help but notice the exhaust temps up into the 1200 range. (Rotax447) Unfortunately I did not scroll through the monitor to see both cylinders just the highest was showing. What is a normal looking cruise temp, say 5500-5800 RPM?

I've added the page from the 447 operating manual that contains the nominal operating temps for the 447. 1200 Deg EGT is max. I've set my Grand Rapids unit to reflect that as Red Line. I normally see EGT  temps around 1120 and  CHT  around 350 during cruise depending on weather. The chart says normal EGT is 860 to 1000. I see the 1000 range during climb out and at wide open throttle but not during cruise. Nose down and unloading the prop causes the EGT  temp to rise quickly. Don't be surprised if you see the EGT rise quickly in the 4000  RPM range. That is the leanest area of the mixture curve for the Carb.  I try to stay out of that area as much as possible. If you experience high EGT all the time, then you may have to visit your prop pitch setting and dial in a little more pitch. I probably could dial in a tad more on mine but my Firefly is performing very well where it's at so I haven't messed with it. I live in Michigan and still have some snow. I hope to be flying by the beginning of April somewhere. Kudos on your Firefly.  Nice Pic

High egt temps could be either or a combination of prop pitch, or possibly running a bit lean.Â  If it has sat for a year you may want to pull the jets and make sure they are clean.Â Â  if they have a film on them that could restrict fuel and lean things some.Â  Or maybe a larger jet.Â Â  Good luck

I thought you got it already.  I seem to remember it was in Ellington.

Thanks everyone for the quick response. I will have look into this much closer after looking at the chart and the responses . I have a three blade Warp drive prop in the corner of the garage I may try out some day but until then I will check and clean the jets, maybe bump up a notch on the needle if I can or change the jet. I also need to check if both cylinders are the same, I worry about seal leaks on two strokes.

Great looking Firefly.  I know the drive you are looking forward to.

I bought my Firefly and most of a Firestar from a guy in New York. (I am in Minnesota) It took two trucks towing two trailers (one came with the Firefly), A small fortune in toll both fees and a hotel night or two. 

Not sure why I did it , but what the heck, Everyone loves a road trip.

If I remember correctly the cold air throws off the EGT reading.  So if it's 30degrees colder than 75F (egt manufacturer calibration temp)  your gauge will show 30degrees higher.



Also the cold air will cause you to run leaner.  I raise my needle a notch in the winter and return it in the spring.

You gotta go by what your sparkplugs read. Use your gauges for set points. In my limited experience, that spike is a false reading from the way the pipe is tuned. I'm not in any way telling you to stay at that throttle setting. I miss my original firestar when it warms up in MN.
