Just wanted to share my latest repair work.
Both the twins started leaking oil at both the base and the head gaskets.
I ordered all the parts, and jumped in with both feet over the weekend.
It was pretty easy. I removed the seat, tank, side covers, carb, exhaust pipe, etc.
located TDC, pulled the head, then the cylinder.
I had A&A racing hone the cylinder and since I already had approx 6K miles on her,
I decided to replace the piston and rings as well.
The cylinder had some light scratches in it that came out when honed.
The timing chain guide (rearward one) had SEVERE wear on it. It was chipping
off pieces of plastic and dropping them in the engine! I replaced this guide as well
It cost about $50 bucks. I encourage you to check the wear when you reach about the
same mileage, or you start seeing black stuff in your oil change!
Everything else went smooth.
The only thing that was tricky was holding the cylinder in one hand, guiding the chain with the other,
making sure it didn't fall off the bottom sprocket, and squeezing the rings etc.
I got it all together, checked everything, and attempted to start her!
Thats when I thought I destroyed the motor!
I forgot that I only filled the fuel tank up with less than 1/2 gallon of gas, and didn't
have the lever on reserve! it started first kick, but then started coughing and went thunk and stopped.
My heart was racing! I figured the fuel problem out and started it again. It ran this time, but only
at Idle! Something was seriously wrong.
This is what I found...
When I lined up the timing chain sprocket with the mark I was sitting on the floor more towards the rear of the bike
instead of directly in front of the mark. needless to say, I was off (1) tooth on the sprocket. The line was in the center
of the link instead of in between two links (I was smart enough to take photos before I started).
Long story short, I pulled the sprocket, rotated it one tooth, the stars aligned, the bike started first kick,
and has never run better! I've got 300 hundred miles on it the first day going 45mph or slower! What a long day that was.
Just wanted to share, as I'm pretty proud of myself.
Now as soon as the wifes bike arrives, I'll do it all over again.
