That is a strange one Ross.  Huh?


Ya, it’s odd.  Not a miss, a definite knock.

Sorry to hear about your machine Ross, that stinks.

I've had a knock like that turn out to be a cracked piston skirt.

  That is very odd for a Yamaha. They make very well engineered bikes and engines. I will be very interested to hear the diagnosis of this knock.
 It could be many different causes.

You are right  Steve.
It's getting a little colder now and perhaps Ross was shivering a bit.
Could the knocking have been his knees rattling against  the gas tank ?

Ross, Tracer forums mention chain noise, which apparently sound like knocks.

.

Ya, thanks Howard, I had read that.  I did a real good inspection of the chain and sprockets.  All looks good with no tension differences along the chain.

 It could be many different causes.

I have to say, I’m not impressed with G. A. Checkpoint communication.  When I dropped the bike off, they said they would call before someone looked at it.  So I waited.  Finally I called them just now.

Turns out the Yamaha warranty guy was there later that day and took it for a ride.  All he said was the chain was way too tight.  Ever since (way back when) someone, Steve I think, pointed out my loose chain, I’ve paid close attention to the tension.  Now, the spec in the manual has the chain really tight.  From all I read about it, the spec is really tight, and should be adhered to.  So I did.  The girl on the phone says that because the chain was so tight, the chain and sprockets are prematurely worn.  I think they look just fine, but oh well, I’ll have them replaced.

But I’ll definitely go in tomorrow to speak with someone face to face about proper tension.  And price/quality options.  Hopefully it’s as simple as worn chain/sprockets.

I wish they had called me.  I’d probably have had the bike back by now, or at least had the chain/sprockets ordered.
