Hi, I am new to the forum and am looking forward to learning a lot more about the Hayabusa engine etc. My project is a 1970 Subaru 360 Van. The previous owner chopped the top about 8 inches (a bit too much) but it still needs a lot of work to finish it. My donor bike was a running 2007 with 8,000 miles. The engine is mounted in the van and I am nearly ready to fire it up for the first time. I may need to fabricate a custom gas tank for it. My understanding is that I can use the pump from the stock tank, though I am not quite sure about the venting requirements. I had to extend the header tubes about 10 inches for clearance purposes and am using a stock Buell Lighting muffler just past the 2 into 1 transitions. I will be parking under my apartment building and will need to be able to drive in and out at all hours so I will need to have a way to keep the noise to a reasonable level. I also incorporated a variable exhaust dump valve for when I am out and about. Also, when the engine was in the bike frame, it smelled as if it was running rich. I would like to ask if anyone has a suggestion for tuning the stock ecu to correct the rich mixture and also a tune that will work with a bit more back pressure than stock. Thanks so much!
