You could use an ignition off another bike. You would have to work out what connections are made when the ignition is ON. Then buy an igntion that makes the same connections. You could use a multimeter to figure out the connections are made or if you can find a wiring diagram for the bike that would tell you the connections. Is that bike a copy of a Japanese bike? If it is the ignition might be the same as the Japanese bike.

There's a manual for a 2006 gsr600. There a bit of information about it in that. Page 4-78 and page 9-20 http://d4ch0l.webd.pl/artur/SuzukiGSR600-Service-Manual2006.pdf

I had that problem after replacing a connector. When you pushed the connector together one of the wires was coming out. It was the tab on the terminal had been flattened and wasn't catching the plastic. Bending the tab out further fixed it in my case. That's a good site for electrical connectors https://www.vehiclewiringproducts.co.uk/

If you found a bad connection repair it and put it back together and see if that fixes it. I've not had a 6V bike or points and condenser bike but I'd imagine with only 6V to play with any bad connection could mean a weak or no spark. I've heard this company is good for electric parts. They should have any parts your need https://www.electrexworld.co.uk/index.html

Nice job. Looks good

If you disconnected the black/white where the red circle to isolate the ignition coil and condsender and briefly touched the positive of the battery to it you might get a spark at the spark plug or you might not. Or instead of that you could take the spark plug out so there's no compression and spin the engine over with a drill attached onto the flywheel nut. At your own risk of course

I agree with the molegrips/vice grips idea. You're lucky. The head of the screw is exposed so you could clamp small vice grips onto the the screw and turn, they will crack loose. The dot on the head of the screw means they're JIS. You could invest in some JIS screwdrivers to prevent stripping in the future

yeah you will have to go for a ride on it and get it fully up to temp before you can say for sure that it's rich. You can foul the plugs like that doing a few starts on the stand and not getting it fully up to temp. On the plus side they look like new plugs to me. Your air filter looked new too so it seems like it was serviced shortly before it was parked which would be great.

I'd take the lining out and give it a wash with soapy water. Let it dry fully and let the helmet dry, then put it back together. How old is the helmet?

You can see the connections in the ignition in this one edit. put the k wiring diagram in

I think in that setup the power for the ignition coil comes from the stator not the battery.

When the ignition switch is in the off position the black/white connects to green which grounds the positive side of the ignition system to prevent spark. When the ignition is in the on position the black/white and green are open so you get spark. I suggested he disconnect the black/white at the ignition to rule out a fault in the ignition switch. disconnect the red circle

Your caliper needs a clean, possibly a rebuild Have a read of the workshop manual before you do the job. Buy the OEM seals. Those cheap ebay seals are junk

Looking at the wiring diagram when the ignition switch is off it stops spark by grounding the ignition system through a black/white wire. To rule out something funny going on in the ignition switch you could try disconnecting that black/white wire and make sure it doesn't touch anything and check if you've got spark. It's not likely to be the issue but if you can get access to that black/white wire it's an easy thing to rule out

This is another good one I saw a while ago

Good choice. They're an excellent bike

If you can find the correct wiring diagram or workshop manual for your bike and post it, it would help a lot

Is this is the right wiring diagram for your bike? https://www.fireblades.org/threads/cbr400rr-wiring-diagrams-haynes.107112/ If it is you can turn the bike on by following the wire coming out of the back of the ignition. Follow it to the block connector where it joins the bike's loom. There should be three wires at the connector Red, Red/Black and Blue/Yellow. If you look at the ignition switch in the wiring diagram it shows that when the ignition is on the three wires join together. So if you join the three wires with some jumper wires into the back of the connector the electrics should turn on the same as if you had turned the key on. So at the connector jump Red to Red/Black and Red to Blue/Yellow and it should come on. The Red is 12V from the battery. The Red/Black goes to the fuse box. The Blue/Yellow goes to the fan motor. So when the ignition is on it switches 12V from the battery to the fuse box and fan motor. That is only correct if that is the correct wiring diagram for your bike

They should bring back the old style chain cover. The chain would last forever with one of them

Just seems like common sense to me but I must be wrong. Not the first time.

You could ask the mechanic when you're picking it up if you should use the clutch or not. Personally I'd play it safe during the break in and use it but that's just my opinion. Sorry that I didn't see that you're female. I don't really pay any attention to the names

Yeah if it has a battery and reg/rec put a battery in and see if that helps. The Suzuki manual I put up for a 1988 DR125 only showed it having a basic electrical system with no battery and no reg/rec so I thought that's what you had. TimR put up a link to a DR125 from 1986 with a full electrical system so there must be two types of DR125 at that period.

Before the trip I needed to get an idea what countries I want to go through as some countries require you to get a visa in your home country (Pakistan and China) and I had to organise crossing through China with a guide in a group - not allowed to cross Xinjiang region on your own with your own vehicle. Apart from that most other visas are possible to get online (evisa) or at the border. I'm trying to just "wing it" as much as I can. So I didn't have any specific route in advance. There were countries/places I really wanted to see (Pamir Highway, northern Pakistan - KKH, Himalayas, Nepal, south east Asia) and before I set off I scribbled some random route on the map that would include these places. Most the time I don't know much about the countries that I enter and only start researching places to visit and routes to take as I enter each country, otherwise I would have to spend years just planning the route if I wanted to do it in advance. When I hear about some place that I think I may want to see I add a marker on Google maps (currently got 263 places marked as "want to see"). That's awesome. Great to see someone living out their dreams. Good luck on the rest of your trip

What a great trip! I'd love to know how you figured out what route to take?

Yeah I read it. He had a moped and a 125 for a year and now he's getting a brand new Honda Rebel. In my opinion he shouldn't be learning clutchless shifting on a brand new bike that's not even broke in yet. Just a bit of mechanical sympathy.
