Yeah about that front gasket.. Replaced all parts you see plus new air filters. Waiting on new fuel filter before i put her back together and fire it up... Hopefully no internal damage from the blown gasket.Dont look that bad...
The porcelain looks good..
The front gasket now that's another thing

Thanks, at least the plugs don't scream engine problems right up front. Not sure what a strap is, but i see no dots on any part of the plugs.Look just a hair lite to me. Hard to see but how do the straps look and are there little dots on them? Exhaust leaks will also mess with your air/fuel ratio so the readings on the plugs will not be 100%.
Are those NGK DPR7EA-9 plugs?Yes little jaunts here & there around town and 87 octane. Good observation
Will do as the last filters will be here by Monday. Yes on the plug part # as well. Thanks.Are those NGK DPR7EA-9 plugs?
Looks like normal threaded stud terminals so you have stock coils. The stock spark plug boots twist-onto the spark plug wires. Said another way, the boots thread-onto the wires. You might clockwise gently twist them fully on.
Were they replaced in recent mileage? The porcelain under the blue tape on one plug looks white enough to be new. And the crush washers appear torqued just once. Hard to know. But all things considered they seem to have been properly installed with good seal and were performing well. The only curiosity is one plug's business-end is clean and the other three are stop-and-go normal sooty.
Let me know how she does with cleaned-up plugs and new Yamaha exhaust gaskets and the head pipes installed with a nice gentle torque.
