Is anyone willing to be a test rider and provide feedback on a flat head engine still using 6 volts? I prefer someone located in the USA, bonus points for Wisconsin or surrounding location to speed up the process of test feed back. Here is the deal...If you would love a Power Arc based C5 ignition and have a 6 volt bike, lets talk. We need feedback on starting, smoothness at idle, performance at higher end of rpm range, and feed back on how the two curves compare. Changes in engine temperature would also be valuable. You will be using our newest coil rated over 100k volts and I will provide a toggle switch for changing between timing curves. I really think the flat head will see greater improvements that on OHV type and we've never had a 6 volt kit until now. Toss that PM-05 ignition and help us out. You will be world famous! Anyone want to give it a go??
The past few weeks I have been working on a new ignition for the flat head models using the PM-05 ignition. Our goal is to remove the entire cable operated "points" type system and replace with a C5 ignition (Power Arc based). Since many of these will end up in non-English speaking countries, and probably in small villages, we insist on creating a kit that does not require any drilling or tapping, no camshaft modifications, and could be reversible. Easy to install, easy to use! Ken and Lorne Ulrich have engines, cams, and motorcycles for this project. I live about an hour away so we've been using U2 Cycles as our "home base" with my materials. What else can you do when the weather is -15 F? First we measured the cam end (inside and out) and all critical heights. Using our existing C5 Ignition kit we created spacers and a new part to hold the encoder disc. The cams on the flat head engine are not threaded for a screw. Today Lorne and I installed and made notes to change a few small things. My machinist is now making a few parts so we can test several designs to securely hold the encoder disc. I am very pleased with the outcome so far, and Lorne was a big help as usual. Even though Ken is on vacation in Texas, we decided to share a few pictures with the forum. While I make the parts, Lorne is focusing on getting one of their flat heads up and running. When the weather gets above zero we can test ride.
