Rode at Ocatillo. Rode up the big shell reef hill. Got ¾ way up and dropped bike somewhat softly. Got down to bottom of hill. Getting dark. Bike Making Weird Smell. Had to drive back since getting dark. All power still in Bike. No residue on bike. Cleaned with enging brite. Let Bike sit for a few weeks. Started up and immediately starting smoking from the the pipe that runs from top of motor to exhaust. Startled like normal. Didn’t ride but sounded same, revved up fine. Brought to Yamaha. Still under warranty. They spend a ½ hour on it and told me my compression was low. I asked what is the normal compression? The said I don’t know. But mine was at 70. 24 hours later they called me back and said that it should be at 90. Firtst they said they can get to it next week. Spend 3 hours tearing the top part of the motor our for it may be blown. I didn’t run it out of oil or coolant. But the bike did seem to be hot from the white smoke rising up from the head pipe. I did have to fill it up with some oil and antifreeze the next morning but didn’t ride it. Now its next week and I havnt given them the go ahead yet. Yamaha dealer now says since I havnt got it tuned up ever that the valves could just be out of wack. That’s why the low compression reading. They want to do the full tune up with parts costing $220. Also, he said a drip down test to see why smoking? I’ve had it almost for 2 years. I have the 2 year Western Warranty. The bike has full power as I remember on that day. I have taken care of the bike pretty well. Not ridden much. Whats your expert opinion? Am I getting the run around.
