Hey guys hopefully I'm getting a yd100 on a felt faker in a few days before I run in I'm going to try do go thru it and trouble shoot any poticial problems. I've heard a couple times the wrist pin clips are crap I went on ahead and got a couple of extra has any body done this is it necessary? I'm a noob when it come to 2 strokes or working on engines in general so I be asking question once I start. As far as jetting the carb should that be done before it breaks in or after? If anybody has any advise or things I need to do before I start it the first time I'd appreciate any and all suggestions. In time I'm going to do a few mods to it after break in so I'm sure I'll have questions. Looking forward to working with you fellas.
