Re: Carbs?
BMW R100S 1977 Bike revs fine up to 3000rpm but reluctant to go higher, i think it is a carb problem, but any tips and suggestions would be gratefully received. Immediate thought was diaphragms. Works fine up to a point, then feels choked, no further rise in rpm...then back off slightly and it feel...

Re: 1978 R100RS Engine Noise
The (edit: I read you now have a S fairing. RS fairing ) can amplify any noise and make it difficult to isolate. Don't discount anything! eg, this fixed a weird noise mine had years back. Put a cable tie around the intake snorkels to take up any slack and see if it goes away. It does sound metallic...

Re: Instrument shrouds
Over the years I've found that a trickle of water can accumulate at 6 o'clock on the dial face and a little may seep down and eventually the soft metal circumference strip deteriorates. With that in mind, I'd be inclined to try some silicone from 4 to 8 o'clock.

Re: R100t first gear jump
gspd has a history of knowing what he's writing about.
However, first thing I'd do is check
1. clutch adjustment

Re: 90/6 ignition switch/key, and indicators
That's a /5 type key/instruments/headlight. 90/6 had separate speedo and tacho, Key into the left side of the headlight?

Re: '73 R75/5 Early SWB and Late LWB Questions?

Re: Pushrod towers leaking
It's a beautiful bike ZM. Good to see you're stilling using it. The last time my left boot had oil spraying onto it, the oil pressure switch was the culprit. Messy, but a cheap and fast fix. An oil switch leak isn't likely to stop when warm though. I topped up 200ml after 200km! (100+100) My left b...

Re: R75/5 blowing fuses when starting
Thanks. Timing was correct and it failed to blow a fuse when the harness was bypassed and when plugs were removed. So, I decided to go back to a poor or bad ground. My good friend and fellow Canadian biker Brett suggested that I replace the ground from the battery to the transmission. After much se...
