Thanks for all the help guys, I tried a new regulator and it didn't help so I just bought a new stator and changed that as well, and now it charges like never before.

I tested it and it showed 3.3 volts between the battery and the red regulator wire. I only understand the basics when it comes to electricity, so where does these 3.3 volts even come from? Does it mean that there is some kind of connection between something where it shouldn’t be a connection?

I charged the battery for 10 hours last night and I have just taken a 2 hour ride. It runs good and still has more than enough power to start the bike. But it didn’t charge... I have measured all three wires from the stator, it shows between 30 and 50 volts depending on the rpm. Maybe it’s the...

Hm.. I can do that, but I can run the bike on the battery only for hours. I have done that the last few days. I take out the battery in the night and charge it for 5-8 hours and I can run the bike for 7-8 hours including 5-6 starts without any issues. It’s weird that it would take charging from...

86 mod Vmax. New regulator, new battery (680), it shows 15 volts when I measure directly on the regulator (when running) with the battery unhooked from the regulator but when I hook on the battery it shows 12, and not charging at all. That’s a new one for me, what in the world could be wrong...

I was half way through a roudabout when the car hit the tyre me on my right side. My speed was about 18 mph and her speed must have been about 20. I can clearly see that the full circle of the side of my rear tyre had been in contact with her bumper at least for one spin maybe more, so it almost...

So after two years of riding I got hit by a car. Speed was about 20-25 km/h (15 mph). The car hit my back wheel on the right side, and the bike landed on the left side on the ground. Bent handle bar, gear shifter, and scratched exhaust among a few other things. I also noticed a weird sound...

There is a new sound coming from the engine, could it be a bearing ? Sounds like it’s coming from the left side but not sure. Sometimes it goes away and then it comes back. https://streamable.com/kiw70x

I actually change the rotors this spring, even though the ones from 86 still were working fine. Had no problem with loosening the screws, but thanks for good advice. I might need it if I buy a new tire, because I used thread lock when I installed the new ones. (Fender is being painted. And I...

Yes, mine are like the front wheel in this picture

My front wheel seems to be slightly bent and starts shaking at 120 km/h or above. Does the front wheel of a 1992 or later fit, my bike is 1986. All I can find are wheels for those later models.

Sync is good when idling, but as you can see from the video one carb (front right) is acting different when revving the engine. Everything is stock except the exhaust. New slides, diaphragms and recently cleaned carbs using the shotgun method. https://streamable.com/6v2xzr

That’s probably the most plausible cause behind idle problems. But just in case anyone else reads this, my problem was actually a poor battery. I knew the battery was poor but didn’t really think it would affect the idle that much. Put a new battery in and the bike is so smooth on idle and take...

Maybe a stupid question, but is the idle mix screw only doing something useful when the bike is idling? Because I do have some trouble with the idling, but when I ride it it seems to be working fine.

I have been fixing this bike for 2 years now, basically everything is new and working good now, and finally got my license a month ago. And then these things happen. I can get a new carb, but then I will have to wait for several weeks again. How much would a used carb body cost me? I guess I...

So it's not possible to carefully fill the hole with something kind of product, re drill it, and make new threads?

Do you know which thread tap I need for that?

The threads on the idle a/f mixture screw seems to be damaged. There is nothing wrong with the screw itself, the damage is on the carburetor. If I turn the idle a/f mixture screw all the way in, I can only turn it back out 2 rounds before it's completely loose. I'm supposed to turn it out about...

So I finally had some time to start working on this again, and I need to find a solution. It doesn’t seem to be a Dynojet kit on this bike like I thought. The needles and the jets are all original. The jets are 170 and 90 so also original. It looks like the slides have been drilled, the hole is...

Is it strange that I have one of the Dynojet kits but still has the original air filter? And is there a way to figure out what kind of Stage the kit is? I guess the carb tuning is different for the different kits? I am still not sure if I want to buy the Vboost system or just try to make the...
