Barry -

From one Marylander to another, welcome to the forum!

Couple of thoughts regarding your issues:

What is the state of your charging system? A "good" battery is as "good" as its charging system....you may want to check and be sure your grounding system is sound.....also, what is the amp rating on your battery? Does it pass the "load"test?

Wet sumping:

Are we talking a bit of oil burning (seems to be fairly common with triples) or puking oil out the breather? Over on the triples forum, valve stem seals are discussed regarding this....

I'm no expert with these bikes, knowing even less about triples, but I can at least get the thread started! grin

Cheers,

Steve

Welcome to the forum.

There are fixes for the Lucas starter, do a board-wide "search". It seems that Nortons also have the same problem on their 850 ES models. I believe the fix has to do with converting the starter from 2-brush to a 4-brush unit. There are numerous shops that can do this conversion through the mail if you do not feel up to it. I don't work on a lot of ES models, so I'm not too keen on the details, only aware of its existence.

On the wet sumping issue... I suppose you're talking of "oil wet sumping" as opposed to "fuel wet sumping". The 3-cyl machines have a one-way valve that can get some trash under the ball. You only need to clean the ball and seat. However this may only be a symptom of the problem that you have not been changing your oil filter enough. With good 20W50 and a fresh filter you should be "good to go".

You might also check the 3-cylinder forum for help too.

Again welcome. Hope this helps! bigt

ca, us
I make a planetary gear starter as a direct replacement for the Lucas but it requires changing to negative ground. One guy has a high compression big bore race bike with a similar problem (bad knee) and it works for him.
Wet sumping can come from three places, the afore mentioned anti-drain valve (located after the pump), the over pressure valve and from a leaking pump (body or gasket). The pumps do not have gaskets between the sections, only at the base, but a thin smear of Loctite Gasket Eliminator can be used between the sections.
911 adjusters will cut down on valve wear and adjustment.
TriplesOnLine.com is another source of triple information.

The four-brush conversion is certainly a worthwhile modification for the Norton Commando Prestolite electric starter, although the single biggest improvement is (in my opinion) fitting a battery with sufficient CCAs to crank it, along with heavier starter cables that can actually handle the Amps.

The T160 uses the Lucas M3 starter motor, and that already is a four-brush motor.

Fitting a high power (AGM) battery to the T160 is a worthwhile upgrade in my opinion. Also fitting a Tri-Spark electronic ignition would probably help the bike to start a lot better?

So, where are all you Maryland Brit bikers? Up until recently, my Norton Commando was my everyday bike, and I virtually NEVER see another Brit bike on the road around here. I never see another tube-frame Buell either, which is my newer everyday bike, but that's another story. The Norton would like a play date with a bike its own age.
