I sure hope there is a good ending to this thread. I can't imagine all the time and effort going for not.

Third fill-up i've tracked for economy.
Even though the engine is making nasty noises my fuel economy seems to have jumped.
I went from an average of 68 mpg to 77 mpg.
To bad it still sounds like it wants to throw a piston or rod out the side.
600 miles on build now. Already changed oil at 300 miles. Changing oil and filter soon now that the
motor has loosened up.
I just wish I knew what the metal rapping sound was coming from.

Other than the rapping sound it appears your efforts have been rewarded. I'm just hoping it doesn't grenade and hurt you while riding.

I'll second that.

Ok.... I stopped and thought about this for a bit.
Why isn't it blowing up with this metallic knocking sound?!?!

And it came to me Saturday. Derbydave's statement about chasing my tail.

I thought maybe this is something stupid simple....
So I take a mallet and start tapping all about the engine, frame and exhaust....
... And there it is... The left exhaust pipe is in contact with the motor case on the bottom.
Welp.. I bend it away from the motor case and went for a test drive.
The metal rapping sound is almost gone! The pipe was acting as a loudspeaker for all the engines
internal noises!
I just have a very very mild slap/knock sound now.

Bottom line.

The third tear down and reassembly was the last one necessary. Just needed to shim the motor for proper deck height and I was done.
My bent up, and cracked open, exhaust was my loud nasty sound problem.

Dunno why I still have a quiet rapping sound still. But hey! I can ride it without thinking it's gonna bite me now

That is good news, spldart. May the force be with you.

Water Warrior 2 · 04-11-2017, 02:50 AM

Excellent thinking and great results. Now we can get on to some fun stuff. Everyone in favor just rev your engine.

derbydave · 04-12-2017, 11:40 AM

I'm glad you finally figured out your noise. In my over 20 years turning wrenches I have gotten burned more times then I would like to admit when I started to overthink the problem.

spldart · 04-23-2017, 05:30 PM

81.623 mpg without trying.
Incredible!
Noise continues to grow.
Just bizarre.
Two sets of gaskets on the way for another tear down.
I'll post pictures whether it's nothing or I find something.

If you are going to be tearing it down again. I would check and make sure that all of your bearing clearances are in the service limits.
