Experienced Moto Mechanics step in please!!!
I just finished changing the second gear in my 99 yamaha r6 and everything went great. I got it all back together and back in the bike and it ran and drove great. A few days later I'm riding down the freeway, 70MPH nothing crazy and all of the sudden the bike won't accelerate and keeps slowing down, so I pull in the clutch and she dies and won't start again. The temp guage was reading normal and the oil pressure light didn't come on. The bike has no compression now. I initially thought that I somehow overheated the head by not having enough coolant, but the radiator is full, and I think that I would have had a problem with this earlier.
Here's what I think it is: I think that I blew the timing chain somehow. There is no water in the oil nor any oil in the water so I'm pretty sure I didn't burn a head gasket. When I was tearing down the engine for the second gear I did take the bolt that holds the crank gear off, but when I re-installed it I used blue loctite and torqued it to the specs in the book.
Here's my question: Is the Yamaha R6 engine an interference engine?
The bottom end of the engine spins freely when the starter is engaged and I don't here any carnage, so I hope that the pistons and valves survived and I just have to change the chain/tensioner/gears.
Any input on this is greatly appreciated.
