Just took my barrel into the machinist to get her cleaned up for a new top end and he spotted this.. Any idea what these little milled slots are just above the exhaust ports? I have not seen them on my other 2 strokes before... bike is a 91 CR500.
Cheers
What is this inside my barrel?!
Sweet... thought so.other wrote:Decompression scallops to ease starting . . . standard on all CR5's, and most other non power-valve big-bore 2 strokes. Is that your barrel up at 360 S&C ? if so, dood, that needs some attention from a hone !
Yeh it was... picked it up today and wasn't super impressed with it
