The original Stratus comes with 162 main and 40 needle jet Bing standard sizes are 165, 170, 175 etc. Bing suggested trying 170 to 180 for main jets when EGTs are reaching 1500. Stratus considers a more conservative two size increase. Would be interested in knowing what others have arrived at here. Thanks all, Larry McFarland - 601HDS ________________________________ Message 2 _____________________________________ Time: 07:12:30 AM PST US From: "The Meiste's" Subject: Re: Stratus-List: Jet Size for Stratus with Ram Valves and Bings --> Stratus-List message posted by: "The Meiste's" Hi Larry, I have not had my heads re-worked yet but I'll give you my 2 cents anyway. When I simply moved my clip one notch it had a huge difference in the color of my plugs. Before moving my clips my plugs were dry and very light tan color. And now they are black and slightly wet also. If I remember correctly from my ultralight days, moving the clip one notch is equal to changing the main jet one size. When flying my Challenger with the Rotax 503 I had to have three different sets of main jets, one set for winter, one set for summer, and a third set for spring & fall. I'm not sure if these alt comp carbs require jet changes for different seasons or not??? So my advise would be to make gradual adjustments here, and keep an eye on the plugs as you go. Have a great 4th! Kelly > Has anyone with the Stratus engine and with Ram Performance > heads and Bing Carburetors have any data on what jet sizes they finally ended up > using afterward?
