I just got my 2056 back from my engine builder, and now im trying to install all the sheet metal. The engine builder suggested that i wire open my cooling system so that it doesnt ever mess up and overheat my engine. My question is how should the flaps be oriented if i wire them open. Why do i even need these flaps if im not using the thermostat system? IF anyone has any pics of how they oriented their flaps, that would help alot. Thanks!! Hopefully back on the road soon!!

I noticed this morning the engine was running "cool" on the temp gauge. Popped the lid when I got to work, yup the little cable worked loose. Gotta fix it.
Had that not happened to me this morning, I'm pretty sure I wouldn't have bothered posting to this thread. This has been hashed out so many times I've tossed my arms up in the air to it. People will do what they want anyway. BTW - with my 914 running cooler and having carbs, it pretty much ran like poo the whole way to work. Never really warmed up to what I have things tuned to. FI will most likely compensate for the cooler running, but carbs generally don't. |

FI will most likely compensate for the cooler running, but carbs generally don't. Assuming your cooling flaps are installed correctly with the springs in place, if the cable came loose from the pinch bolt (or if the cable broke), the flaps would spring open to the "warmed up" position. Assuming your drive to work was at least 15 minutes, the engine oil should have come up to operating tempurature by then. I think you may have a different problem, maybe with your carbs. I have my cooling flaps installed and connected to the thermostat. My engine running dual carbs runs fine right out of the gate and continues to run great after the oil is fully warmed up. Correct me if I'm wrong, but the heads and the combustion chamber come up to temps pretty damn quick, like in a manner of minutes. Not sure how oil temps make the engine run like poo. |

The heads come up to temp fast, but can also lose it fast, particularly on down hill runs, off throttle. I will regularly see my head temps drop into the 220 - 250 range, especially on my drive to work on a cooler morning. Its all fast, long downhills. Optimal temps are ~270-370. Zach |
