Frame Question w/pic

" But both of my 64/65 scrambler frames have the rear loop kick up. I thought all the scrambler frames had the loop kick up so the rear tire could have more space in the the fender well. Mine are definately not flat
My 2 cents. "

____ Well your '2-cents' would certainly count here if the frame in question had also been a "scrambler" ! _ Cuz compared to the 'Monza' models, the Scrambler-models do indeed have an uplifted rear frame-loop. _ BUT not to that same (relatively extreme!) degree of upward angle-slant of the frame pictured (in this thread's opening-post) !
That rear-loop's radical upward-bend should be still quite notable even compared to that of a stock/normal Scrambler.

I've measured a few of these frames, and this drawing will give you an idea of what I've found- it does vary a bit.

I've also found that it's much easier to bend a tube than it is to straighten a bent tube- I'd suggest you find some scrap tube and experiment before working on your frame, it's so easy to get a wrinkle and so hard to get a wrinkle out. Bending the new angle in the tube won't be so bad, but getting that bent section of tube to look really flat again will take some careful work.

I looked at your picture again, and it looks like the factory bend is still there- if you can get the other bend straightened out you probably won't need to do any more.

____ Nice post Rick !
Do you happen to have another rear frame-loop drawing depicting that of a n-c Scrambler-frame, so the two different frame-loops can be obviously compared ?

____ That's no-doubt going to be the case when that bend is not heated-up & straightened-out by someone with professional-level experience with such.
__ I'd suggest that before the actual re-bending is attempted, a sturdy length of (preferably square) bar/tubing be well clamped to the underside of the frame-tubing forward of the bend to be re-bent. _ That way when the (unheated) rear of the loop is forced downward, the heated bend will then floor-out against the bar-stock so as to help prevent unwanted downward curving (elsewhere other than where wanted). _ As then the rear-loop will bottom-out (without any point being able to go further down & past the desired flat-line) and thus stay flatly-lined with the original flat line of the frame-tubing.
This added precaution should get one by without much pre-job practice.

Thanks for all the ideas on this everyone! And thanks for the diagram Rick.

Bob,
Here's a drawing that show both the scrambler and street profiles:

Guzzijon-
This drawing has an easier to understand dimension for the bend location.
The scrambler has an additional bend just inside of the gusset.

Thanks for posting that!

My 66 Scrambler frame has "some" curve to it but not as much as yours shows. I had to remove the stock cross brace between the shocks in order to mount the cafe' seat that i wanted. I cheated and used the loop off of an old Hodaka frame i had that fit perfect. Once rewelded and powder coated it looks good.
