Thanks.
I found battery dimensions and made a box.
A cardboard box.
For visualizing:

something to consider, electrical stuff gets hot, hot stuff fails. might consider just making a metal band to strap it in place vs. a fully enclosed box. you'll get more ventilation and keep it cooler.

As stated the box was for visualizing and it became apparant that the area was too small to accomodate the battery. I have dimensions for Harley electric start battery's. Easily obtained and replaced.
All of this mess will be gone , the silly suicide scenario shifter mount , and the plate and lower fender mount. The fender is gonna be cut off, there is a chain cut that goes 2" into the tire area anyway that can be cut right off and the battery box can block most of the road grime. I need this area clear to get the battery down onto the frame rail , where a proper mount will be installed:

Ya so I went on to removal , first the "brake stay" mount. I didnt take a pic as it came off and the "weld" cleaned off quickly.
The big solid 1" bar that was to be used for a shift handle wsa next. It was as scary as the stay ,so I took a pic:
https://i.ibb.co/XCH19q7/IMG-7326.jpg
The blued part is the 1" bar, you can easily see there was little penetration of the weld into the bar. The stay was the same way so off it all came , fender mounts (off center any way):
https://i.ibb.co/6b65Kf0/IMG-7329.jpg
I managed to sand it smooth without too much parent metal removal.There are some other tabs attached by the previous "welder" including the kickstand mount , which I'll grind out and run some hot mig wire into it. Good to find this out now, rather than have parts falling off the bike as it goes down the road.

absolutely. you have the luxury of seeing the metal for what it is and can cut/reinforce where necessary before you have it painted, powdered, or chromed.

Well ; CUE THE MIDGET:
"That aint gonna werk"!

A stock sized battery will not fit into the space. I cut my cardboard box down until it fit without too much size loss. Then spent a few hours researching battery's , then went on a m/c parts suppliers page and found a number of smaller battery's that ill fit in the box size. With 3 battery's that are easily supplied and with enough power to crank the starter , I'll go ahead and get a box fabbed up, one with a side opening and easy access to the terminals:

the frame i had on the Gripper bike I have would only allow for a small, and what i considered undersized battery. it had a tray in the swingarm in front of the rear tire. i ended up modifying the tray to allow the battery to lay on it's side with terminals facing forward, a piece of steel strap on top, then two pieces of 1/4" all thread between the top strap and the tray. that allowed me to keep the battery back there while allowing a decent battery that wouldn't have me crossing fingers every time i tried to start it. i ended up with a braille glassmat battery that has been really good. i keep it on a battery tender junior which seems to help extend the life well too.

I used a small lithium battery by Scorpion having no room for regular.

pretty powerful for it's size.


Dimensions (LxWxH): 6 7⁄8 x 3 7⁄16 x 5 1⁄8 in

Lots of thought went into it.
Ends drop in and bolt at the top for removal.
Rubber pipe to insulate wires entering the box.
Bottom mount to the 3/16" flat bar which will be welded to the frame.
1/8 & 1/4 " Komatex close cell material will be used for the interior bottom and sides.
3 batteries in the J&P catalogue will fit , a hold down will be made when the chosen battery arrives.

good move using perf'd mat'l so it can stay cooler

JamesS 09-22-2020 03:47 PM

Thanks.
The perforated metal was left over from signwork.
Checking and double checking as I go , problems get solved and new ones arise. The oil tank was never mounted properly. I fabbed a 4th mount and clearanced the tranny mount ;
https://i.ibb.co/jTNKsBw/IMG-7381.jpg
Got the tank in place and then found out why there is no 5th tranny mount;
https://i.ibb.co/k5N2rYD/IMG-7387.jpg
The crap-ass tank has a crack already so sectioning out a piece for the mount isnt adding a lot of work.

JamesS 09-22-2020 07:59 PM

More sorting of the oil tank , so much in the way I just started grinding off the obstructions, mostly the rear trans mount. Now the tank goes in smooth and bolts up nicely. The final obstruction was the 5th trans mount bolt. Here is the tank with the section removed to clear the bolt and mount;
https://i.ibb.co/WKCND4G/IMG-7388.jpg
I took out the existing trough and will replace with a slanted piece ,alleviating some of the trickier tig welding to come.

JamesS 09-26-2020 06:16 PM

Mounting brackets and the hole in the tank:
https://i.ibb.co/YhjGvQF/IMG-7394.jpg

There are a tail/licence , 2 x rear turn signal , 4th oil tank , 5th trans , chain guard mouints and 2 'runners' to go on the underside of the frame , as the oil tank is below the frame rails and the drain plug is dangerously the lowest part of the bike. These runners will straddle the tank.

JamesS 09-29-2020 09:54 AM

A 2" x 2" x 6" section of 1/4" angle is cut and formed into a rear fender bracket:

Welded up and ready to go on the frame:
