  1. Proper break in process

    What is your suggestion for proper break in? Always open to ideas. Thanks!
  2. How much oil should mist from the crankcase vent?

    1963 r69s. Rebuilt top end of the motor due to a meltdown, new pistons, last overbore, etc. The story has been told here before. The bike seems (knock wood) to be ok now, have about 250 to 350...

    The hole in the road where I throw money!

    Went on another ride, about 50 miles. Had it up to about 60, and it still felt and sounded good. Gassed up by my house, and the left side saddlebag was gone! Retraced the ride, it is gone. The...

    Success, part 2

    I got my parts from vech, and a nice 2 hours later, an oil tight bike!
    I actually waited a few days to allow the gaskets to seal, but after flooding the bike (here's a tip- if you have gas coming...

    New style, flat bottom

    Nope, it's new all around. Thin layer of sealant( perhaps too thin), but the base of the cylinder is flat. Per the barrington book, these require the paper gaskets. The style that has the...

    1963 r69s success!*

    The good news- I decided to give it one last go. Took the carbs off, cleaned everything (but I can't say it looked too bad, blasted the jets and passages, put it all together, 3 count tickle, 3...

    I guess what don't get is why is this such a bear to start. All the articles seem to indicate that a kick or to should do it, but that's never been my experience. I also have to think that this is...

    I went out this pm, and adjusted the slide stops. The left side fine, the right, it wouldn't lift the slide at all. Heres a pic showing why. I had a spare slide, so in it went.

    On top of that,...

    Careful with that gasket sealant!

    You may recall I had a meltdown in my 1963 r69s. Both pistons melted, left worse than right.

    So, I have cleaned out the melted piston bits from the head, scraped off the melted piston from the...

    Better pic of the valves

    I'm mostly concerned about the crap below the valve guide area and above the seat on both valves. I'm assuming that it could come off fairly easily, but it may require a little "persuasion". As...

    Does this valve look ok to you?

    So I had a melt down in my r69s, lean carb + advanced timing + who knows what. Got the new pistons from vech, bores done, so I'm looking at top end stuff now. The chamber looks ok, scraped a little...

    You do see correctly. Burned away. The other side is harder to see, but it too has been burned up, just not as bad. I think it is the pics that make it look like the valves are sunken.

    Here's the rider's left cylinder head. I did an old fashioned leak down by putting gas in it, and after 10 min, it still held, so I may be OK there... The right side pics didn't come out, but it...

    I will totally own up to this. I bought this bike without even starting it. It had no gas, but I took one look at it, and it was the bike of my dreams. I was only a few miles from my house, so I...

    So I couldn't resist, and I tried to start it today. Zilch.

    My father in law is a mechanic, and he lent me his compression tester. 30 psi left, 60 right, and leaks down immediately. Oil in the...
