Well .. the bike is running!! Thanks for all the advice from
@KevA absolutely flawless with the info his given me!
When I lifted the fuel tank to check for kinks we found a split pipe on one of the original hoses so drained the tank, flipped it on its side and replaced all the original lines. The bike still didn't want to start and eventually killed the battery off so we tried a battery of my mates CBR but still nothing. By this time I had run out light so left it.
Today I was planning on testing the fuel pump and with more advice from Kev, drain the carb bowls to check for water as the bike had been stood stripped down and left in the open for a few months before it came to me, it was instantly covered when I got it and a make shift workshop (trampoline frame and tent) made so I could work in the rain but had suspected carp to be in the carbs but at the same time my friend had a arrived with someone from the fmgarage that are testing the regulator for us and a trailer ready to take the bike away but decided to put jump leads on the bike... We had tried them several times yesterday but today the bike fired up instantly, ran fine and rode up and down the street a few times with no visible problems or noises so it has now gone to the garage for the final checks on regulator and charging system so fingers crossed the bike is fixed!!
The issue with the bike when it arrived was no power at all and a complet none starter... The cause turned out to be a dead contact in the ignition due to a bump in the circuit board and locked contact pin, pictures are included above if anyone has a similar issue, my fix will not be permanent as the barrel is showing signs of a fault as the key can be removed with the engine running so a new barrel will be ordered.
The burnt wires on the kill switch were for the lights, at some point the fuse for the light had been updated so would of burnt out later and possibly damage wires but it was also wrapped in foil at one point to stop the fuse popping, again leading to possible burnt wiring. With this, I cut those 2 wires out til I could find "good" wire then soldered a new wire in place and heat shrinker it, rather than cutting the main loom, I used clip on joiners as I had also damaged the locating pin on the back casing of the kill switch so have had to use a screw as a temporary fix to lock the switch in place to stop it spinning with the throttle so again, this will be getting replaced completely to get a firm grip on the locating hole and also know that wiring is factory finish so hopefully will never have the same issues anytime soon 🤞
Again, a huge thanks to kev for all the help with this, it's very appreciated!!
