When I first learned where the points were and had a manual to refer to I opened the points cover to find a little rag in there, which made me scratch head on why, then in my innocence I thought, oh them cleaver humidity hounded Brits had a simple way to prevent water splashing inside. Then I learned the truth about cam seal by oil stain. I'm pretty impressed with Lucas endurance considering the cost efficiency for road craft but don't forget the Lucas also made world class avionics on their hi end contracts. My Nortons take rain and water crossing and power washing better than my SuVee twin, which has sunken deep plug holes that require a tiny drain that tends to clog then fouling begins then no run at t'all. Also Suzunki's issued SV's with 20K mile life rec/reg, about which time they strand you out of the blue. Signals wires are thread like with tiny connectors that behave like Boyer triggers wires. Some of the most tiddy color coded and gear head pleasing arranged I've ever seen was on an unmolested barn find 73 750 that showed up in Baxters while there for their rally and mechanic lifted the tank and both our eyes widened with the grins as the dust sprayed off for show room new revelation. If they'd just used some better alloy in the bullet connectors they may be the world's best looking most compact and handy road going terminals ever sold. If we can write a chapter in a manual on all of Lucas faults, into the Japan Motorcyle owners club for volumes and volumes of book length complaints recalls and substitutes. Not sure the Italians even bothered as all of it decayed pretty quick.
The most water proof test was done by my bud Wesley, after a rain low water bridge, just a flat slab, had less than a foot flowing over so took off and did fine till he/bike fell into a missing section of concert to the tank level, he nailed it and rear caught traction and lifted him back to grade and only stumbled some then cleared up fine. He still had the old air box which must of had just enough volume and over head air suckage. Wes said water had started to tip him over before clearing the hole, which would of washed him over the down side which was like 4-5 foot deep turmoil of foaming water that is not boyant enough to swim in even w/o the back wash eddie.
On SuVee, I tried an 18" deep river low water crossing, crossing kind of upstream diagonal to flow so could head into the current wth power which did good until just before opposite bank there was a dip in cement and bike started to sweep out from under me and align to current and flush over the edge but rear hit buttom in time to push us on up and out. That was pure stupid but what a lasting memory with water falls of spray parting up over head as I entered at like 40 mph but only 5 by the end. It did stumble some which helped add to the drama. Ah the sounds of headers under water...
