I had NGK resistor caps go open circuit when measured with an ohm meter. They still passed a spark but I suspected it was a little weak. I dismantled them and found corrosion on the internal contact with the resistor which when cleaned up resolved the problem. To get them apart grab the bit that scr...

To get 13.3 Volts means the charging system is doing something. Only just Just off idle you wouldn't expect to see more than 13.3 volts so when you say off idle what revs are we talking about and does the voltage increase at higher revs to 14.0 Volts or something near ? That’s the problem, the volt...

You cannot look at float level alone you have to look at the entire carburettor as a whole, if you look at it there will be an upper and lower limit for the float height and in no way can you set the float level via how high the level is in the float bowl. As far as I know there is no specification...

... the exact level isn't as critical as many people would like to think. +1. Just had to chime in here. The fuel(float) level has to be within the range between too high (overflowing when parked) and too low (starving for fuel at full throttle in top gear). Picture what's actually happening in the...

My bike runs rich thought the range. I weighed the floats and they both seem to be around 12.5 (ISH) gms on cheapy electronic kitchen scales. I put a clear float bowl on with the carbs fitted and the levels are a couple of mm below the gasket face on the forward (lower) edge of the float bowl. Does...

I suppose if the float needle is visibly worn then it will affect the fuel level slightly even if it doesn't leak. The fact that they are spring loaded will reduce the amount of pressure that the floats can exert on the needle and tend to keep it seated so perhaps that limits wear. Mine still look g...

Screenshot 2024-03-24 at 11-01-30 Bing Carburetor floats on BMW Airhead Motorcycles.png Snowbum says new floats on all Bings are 10gm. He also says 13.5gm is likely "maximum allowable". Ongoing adjustment might extend their usefulness, they'll need replacing eventually. https://bmwmotorcy...

I'm in no doubt that floats absorb fuel and become heavier. I've even noticed it with new floats that initially gain a small amount of weight. Basically if you don't know the weight of your floats then you don't know the fuel level is set correctly short of a see through float bowl or sight tube. Yo...

Welcome Chris, I've never heard anyone do what you have described on any of the airhead forums over the last 17 years. While it may be technically possible to fit a screw adjustment, I wonder if it's a little over the top but I do like the precision approach. I'm not familiar with the detail of thos...
