Ok I’m getting the larger of the two. I’m not even sure which is the larger. Back to google. Hey this is me searching for my answers. I wasn’t a part of a gas bike forum till a couple days ago. I know the efficiency and ease of finding what your looking for on forums. If you want to recommend me a link I’ll be glad to read. I’m trying to get my bike back up and running. Not play Marco pollo with the info I seek.
