Welded Frame, Bike wont start.

[Jim]

Back in the day......I was a pup...there was this mechanic @ local shop - one of the best, fastest line mech's ever. He was semi-literate though, so when it came to wiring issues he'd "jumper the fuse and watch for the smoke" Lol (really). When he first started work, the backlog was 3 months, after a month, it was a week.

Had a guy worked for me in the Air Force... decided to bypass a circuit breaker using the same logic.... look for the smoke. F-15 Attack Radar system. When the smoke cleared... pun intended.... was over a half a million dollars in damage.
Not the best troubleshooting method.

Hahhahaha
Those are the spectacular mistakes .. That should be Photographed. .
I remember one dropping his Construction helmet into brand new Fan with the doors open for adjustment smashing the Wheel
One reversing over a Bicycle with a excavator. The boys bought him a 6 - 7 feet flag that are on children's bikes to put on a bicycle

But perhaps the most entertaining that allegedly happened.
Was that a contractor .. had an workorder tearing down demolition a house on Bongoroad no 5 with the big excavator
But the handwriting was not up to par to use a golf term so he tore down Bongoroad no 7 instead.
The wrong house.
That is some homecoming from a long workday ..

Sorry if off topic but its easier to work with a smile on the face

I have also heard it of HiFi amplifiers ..that if you get it wrong the small faults takes out all stages.

Headlight relay got the short! Got that sorted out

 

[jpdevol]

Might check blue wire and yellow harness wires at that connector for short. Yellow goes to stator and might show some resistance, but not full continuity. Blue is lights and should have none.

 

[jpdevol]

R/Y there too - it goes back to fuse box

 

[Jim]

Headlight relay got the short! Got that sorted out

You sure?
Power goes into that relay, comes back out and goes to the Starter Circuit Cutoff Relay. In other words, it could still be downstream of the headlight relay.
You need to start giving us better descriptions than .... "got that sorted."

I hope you do, but better info would help us know what's going on. Jus' sayin'....

 

[nikiforova]

The bottom of it was making contact with my electronics tray causing the wires connected to there, one being r/w, to short. It’s up and running now. Getting 14 volts at 2k rpm and 14.5 at 3k. I also went to check my timing and my magnet fell off. It doesn’t pass the slap test anymore, but the timing is still advancing the way it should

What slap test are you referring to?

 

[nikiforova]

T

What slap test are you referring to?

Rotor magnet

 

[Jim]

Never heard of a slap test for the magnet.

Been reading this epoxied on magnet with interest...
Just for context.... I've rewound well over 200 XS rotors now.... I'd guess at least 50 of those were the TCI rotors.
I've yet to run across a weak magnet. I'm not saying they don't exist... but I never seen one.

Here's a suggestion.
Clean up the epoxy on the rotor.
Charge the battery.
Disconnect the reg/rec.
Start the bike and lets sort out the ignition system ... check/adjust the timing.
Once we're satisfied the iggy is solid, we'll visit the charging system.

Bottom line, if we're chasin' charging issues and iggy issues at the same time, we're just spinnin' our effin' wheels.
One thing at a time. Work it through, then move on.

 

[Jim]

Let's do a test. This is a ring plate off a TCI rotor. Sorry, don't have a complete TCI rotor at the moment....

Here's a Craftsman 14mm socket. If I stick it to the magnet with the ratchet end against the magnet, it holds.
If I stick it to the magnet with the ratchet end facing away from the magnet, it does not hold.
Let's see how strong your magnet is. Don't have to be a Craftsman socket, I just mentioned that for reference only.
If a 14mm will not hold, try a 13mm.... and on down 'till you find one that will hold.

Okay I’ll try this probably tomorrow. I’ve put a lot into this today and I’m feeling pretty exhausted. Got it running with a stable idle ignition timing looks good. Tried to move onto carbs and well, the gauges indicated a late valve timing or leaky intake so uhhh yeah that’s where I’m at

Is all that with it charging properly also?

 

[nikiforova]

It read back 14.2 volts at 3k, 13.5 at idle and 13.9-14 at 2k. The timing also seems to be looking pretty good as well

Those are good numbers. What changed?

tbh I don’t know. I did rewire a bunch of stuff for my electronics tray and maybe something in there helped out? Maybe I was getting bad readings before? Both? Who knows

 

[nikiforova]

Just an update: seems like the problem has been resolved. Bike is up and running, albeit rough, but up and running nonetheless. Gonna do some maintenance and probably start another thread when questions arise. Thank all of y'all so much for your patience and help. I feel like I learned a lot from this tumultuous experience and I'm stoked to have yall to turn to for help

 

[Jan_P]

If you like you can post a video with some throttle blipping .. perhaps we can hear something

 

[nikiforova]

Adjusted the cam chain and set the valve clearances to spec and it’s running much better now, but still not great. It’s also doing a weird thing where it will die when I walk the bike backwards in neutral. Not really sure what to do about that
Idle
Dying when rolling backwards
