Re: R75/5 later carbs

The bike seems to run alright, but its my first airhead and first vintage bike, so I have no idea how it compares to others. Airheads shouldn't run just ' alright '. They should run ' amazingly well' '. My suggestion is to track down a reputable airhead guru in your area and ask him to road test yo...

Re: BMW R80 ignition timing advice

Not sure I understand your question. There is only one 'beancan hall sensor' to adjust. Adjust the beancan so you have the Z mark at over 3000rpm.

Re: BMW R80 ignition timing advice

Timing chain most likely shot.

Re: Float adjustment

....the forces keep the fuel more or less level... hmmmm....????? OK. We need a close-up video of a clear float bowl in actual action to credibly and constructively continue this discussion. My prediction: There will be no discernible level per se., just a bunch of bubbly liquid shaking around allo...

Re: Float adjustment

....to lift fuel from a low volume position in the bowl. You're missing my point. At this point there is no ' low volume position '. Half fill a small clear jar with gas. Tilt it to all extreme bike angles while violently shaking it. Add g-forces in every direction. Mimic the absolute worse road (o...

Re: Float adjustment

... 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...

+1
The heat from gauge illumination bulbs (that are on for long periods) eliminates some condensation.
For flasher, oil, brake warning and gen lights, that are normally on only for a few seconds, no difference.

FYI - These LEDs come with a tiny device that makes them bi-directional.

Re: Clutch pushrod felt seal

Wrap dental floss around the felt to compress it a bit to get it started and then pull out the floss.
