71 R75/5 engine refresh - not sure what I should look for

[nevada72]

I like your Dream.

I was actually looking for a nice Toaster when I bought it years ago. I couldn't find one I liked so I "settled" for the 64 Dream. It's been a fantastic bike.

Handing out candy while working on bikes works well with a airhead tech day also, 12 oz bottles of liquid refreshment ( even if it’s beer ) will not hurt anybody’s feelings either

There are approximately 9 Snickers and Milky Way bars left, which I will make sure to put out.

I'm going to give MANICMECHANIC a call this weekend to set up a tech day, probably in January. Not ideal for camping or riding, but we'll try to make up for it with good food, beverages, and a semi-warm garage to wrench in. Cheryl, pictured above, is holding one of her delicious Whiskey Old Fashions which will certainly be available. And she's a helluva cook as well.



So at the end of the teardown yesterday I noticed this -



I knew it was bent, bu I didn't realize it was fractured. I'm shopping right cylinder heads on Ebay and elsewhere. Any advice in that regard is appreciated.

Bent fin

You can heat that and straighten it. A good welder can tag it back together and you can refinish it for a lot less than buying a used head and having it rebuilt.

Call me later in the day, after 4pm.

If a weld bead is run on the crack, the shrinkage of the weld as it cools will tend to pull the fin straight. Might be enough such that no further action is needed.
