    Got my temp sensors in. Took me a while to figure out how to set them up. Also the instructions are so vague! I did a bunch of forum search and someone mentioned using silicone fuel tubing and just wedging it in place in the rear of the cyl head top fin galley. Hmmmmmmm guess it works, but what a strange way to do this. If someone has used the SBS-01T sensor before and has a better method, let me know.

    Whipped up an air dam for the front dump. I have FINALLY started to use Thingiverse so my .STL will be there for all to use. The AirDam is posted there to download and print yourself. As I am a new member, I'm not allowed to publish anything for 24 hours... not sure why.... silly rules. But here it is:

    It utilizes the same holes as the dump cover plate. I used welders glue to bond it to the cover plate.

    I honestly do not know. I'm guessing they are the same box?

    Flew the plane today. Cylinders are getting too hot I think.

    What is the temp range? I heard 250 and under, not over 300F.

    My right (rear) cylinder is running 30-40F hotter above half throttle.

    I’m thinking of opening up the cowl some more.

    I did adjust the HSN richer about 1/8 turn and it didn’t seem to help.

    Both cylinders were pretty even under half throttle.

    Added some more baffling to the right cylinder to eliminate some gaps.

    Here are some extra pics of how I installed the temp sensors.

    Also the interior as it is right now.

    Also made a larger air dam/dump and installed it. No good pic as the glue is still drying

    Had a few paragliders stop by to visit!

    Cylinders never went over 340! Stayed 275 most the time unless I was wide open.
    Right cylinder was about 20deg higher. Much closer now.

    My air dam V2 worked well. Notice it actually deflected the exhaust residue as well.
