CB750 scrambler project

@Calum cheers man. Its nice to have a bike that's not plastic panels. Raw machine
-
Took so many attempts to get the starting circuit to work. Checked everything, earths, relays, switches, batteries, motor and cables.
The first lithium battery I bought was total crap, couldn't crank the engine over even though cross reference numbers said it was correct. Bought a shido and works perfectly.
Made a numbplate holder + front "number plate"
The most exciting part is the exhaust! Cut off about 10kg of the baffles. Shortened the silencers right down and made up the end covers.
Still got to wrap the exhaust

@Louis-DT-WR very cool looking bike mate. You have a cool helmet design to go with it? Something like a skull with bullet holes would go well with that bike.
@markus-w Cheers mate.
I'm looking at retro Mx or open face.Like these types

@Louis-DT-WR hard choice to make I like all 3. That bike is going to be a good conversation starter. Sure will get some attention.
@markus-w I like the bottom one but looks too modern.
Yes anyone who gets the refe of Lucille will.Genuinely built in the closet thing we've had to the apocalypse

When you buy exhaust wrap, they always rip you off and send you much less
Got one half of the exhaust done.
The fiberglass gets everywhere
.
Cleaned and Sprayed up the rusty bits silver.
The wrapped from the silencer to the flanges.
Heat shields Powder coated blackEngine guards didn't come with any instructions and can't get both sides to fit yet with the brackets that came... Probably have to make more.
-
Finally got the exhaust done.
A few final checks and some cosmetic parts then it's show time.
I did a patina finish to make it rustic... Showing the nickle plate under.
Crash bars on.. only really for a more beefy look.
Can't wait to hear it
Definitely need to get some outside pics. The yellow walls is very distracting

Nearly show timing
1st start up attempts coming soon.Tank now decorated.

Congrats! It’s nice to see someone doing their own thing! Nearly every ride I’ve ever had has been a butchers tripe mix of a thing. Mostly through necessity though!
I’d really love to do a street tracker out of an old Honda CB 200 twin. Nice & lite yet revvy & torquey enough. Think of Girl with the dragon tattoos bike with attitude
️
They aren’t easy to find anymore though... -

I'm not very familiar with this bike or twin terminal coils.
Bike won't start, I believe it's electrical problem.
No spark.The CDI I bought might be the problem.
On the coil it has 2 electrical connectors (both +) and earth's to chassis.
Ignition on and kill switch to run the voltage on 1 terminal (yellow and blue wire) to both coils has 12v.
But there nothing on the other 2 black / white wires. Not even when cranking over.
Surely there should be 12v to both terminals? -
Depends where you are measuring from. The coils job is to take the 12V DC and step it up to 20KV. So you measuring at 12V is outside the scopes range.
12V isn't enough to jump the spark plug gap.
Measuring Coils is usually done through impedance test on the primary to secondary, secondary to spark plug cap. Should fall within the tolerances outlined by the manufacturer.

Its a wasted spark system btw

@Calum thanks, I'm pretty sure both coils are bad. No resistance at all between power/trigger and the caps.
They were second hand, came with the loom.
12.8 volts on the looks power connectors.
New coils, leads and caps on order

Wasted spark is when they both spark at top dead centre?
Have you not gotten any old coil off of another bike? Even a single one that you can get to spark? It would at least prove the rest of the circuit was on par...@SpookDog yes wasted spark system is that.
I've ordered new coils as the primary has 3 ohms which is fine but secondary resistance has no resistance at all. On both. This is 1 fault. I'll have to see if there is others.
They are very old and probably corroded inside -
This is the confusion I have , electrics are not my strongest point.
The manual says the yellow/blue wire goes at the top connector on both coils...
The coils are not handed so the green terminal is at the top on one side and black at the bottom when installed.
That's a what's confusing me
I'm still waiting for the new plug caps to try.I'm also not sure if I need to loop the sidestand indicator light as I removed it... I'm pretty sure it just piggybacks
