Hey team! This is my first post. Great to be here! Just a quick question about Honda VTR 250 engine types, if a anyone is in the know. I've just done an engine swap in my 98 Honda VTR, as the first engine had a blown head gasket. The new engine is a bit newer, from a 2001 bike. All is looking good, aside from two extra pipes that come off the top of the valve covers for each cylinder. They look as though they might be breather lines, as when the engine is idling they make it quite loud, unless blocked up. Just wondering if anyone knows what these two extra outlets might be and where they should lead to? Can get some photos if anyone is keen to help out. Thanks all!
