Bought a non runner in Vancouver

[TURBO200R4]

just because it is new doesn't mean it will start the rocket.
i bought a brand new super wally battery and the guy that was helping me kept his car running about 40 minutes before it would start.
when u crank the rocket if the batt voltage drops below 10 volts it will disengage the starter (relay)
then volts go up and u can do it again. clicking
a little story when cold below 40f mine would crank slow and i believe the injectors did not have enough volts to let them work. a shot of either would make it come alive i finally put the bigger starter on and have no more problems.

Hammer, back in the Late 70's I was working in a M/C shop and had a 400 Honda that had a mis fire that we could not track down.
There was the exact same second hand bike in the show room so I bought that out to the work shop and systematically started swapping parts.
Starting with the easiest things first.

First I swapped the carbs over, this made no difference so left the swapped ones in place, next was the spark plugs, again no difference so didn't swap them back, next the coils etc etc.
In the end it turned out to be the rectifier which was hard wired into the Alternator.

My point is, you have done a lot of work so possibly you should start swapping components with a known good bike.
I would start with the starter motor.

ps
they make a gauge to check the draw of the battery normal is about 100 amps for 100 cubic inches
that would put the draw at 140 amps.

Pulled the starter. Idk how this thing turns over but not sure if this is causing my voltage drop.

Connections inside the solenoid look good to me.

Contacts on the starter solenoid look arched to me and the plunger will be the same. I remove the L shaped copper contacts and clean the contact area up on a linishing belt and also touch the plunger as well. When reinstalling the copper parts put them in finger tight then put the plunger in and push it all the way down to alight the plunger and contacts then tighten. Then with a felt tip pen colour the contact area reinsert the plunger pushing to the button and twist on the contacts - pull the plunger to inspect to see if you have a good contact area. If so reassemble and refit - test

Also check the starter motor side, this was one of mine.

I soaked this part in white vinegar for a week and hear it is

Yup I'll look into that. Was also reading on here regarding the Toyota Camry starter motor swap. There are quite a few in the local pickapart and starters are on sale this week for $22. Might pick one up and screw around with it.

Going to take my new battery back. Pretty sure it's a lemon. I charged up the old battery and it holds voltage during cranking much better.
