Bought a Solex a couple months ago and I'm trying to squeeze another mph or 2 out of it. I say Treats had a larger cylinder kit for it, but haven't found any other information on them. Does anyone know anything about the 41mm cylinder kit? How to install it, performance gains, etc. Thanks in advance
