Engine oil cooler

Was just saying that because IMHO, if the goal is to have fun in racing and breaking laps records, better go with a moderne bike instead of trying to bring an old old engine whose design dates back to the 30s / 40s to the performance of a modern bike.

Will spend much more time having fun on the track than at the workshop in trying to bring something where it wasn't designed to go. It's just like climbing the Mt Blanc with sneakers and a lot of sockets. A lot of people is doing it every year, but is it really a good idea?

But fortunately we live in a democracy (for how long?) and everyone can still do what they want with their money.

All this only IMHO of course, not to offense anybody.

And Merry Christmas ;)


PS: If planning to do races only, and not stop&go in traffic, is not there someone who makes a tank with a baffle under it to bring fresh air to the cylinder head?
 
Fortunately NKN the majority of enthusiasts are of the same mindset as you. This is good, it helps preserving old machines for future generations.

I’m not one of you though. And I’m surprised you don’t get it. Riding, say, a Honda CBR around the track is, of course, much easier... but it hardly begins to compare with the thrill of thrashing a nicely tuned big old Brit twin around a track !

It would also be rather frowned upon if one were to enter a nice modern Honda in a pre 1972 classic class !
 
Sort of on topic: we talked about maintaining oil tank temps high enough to evaporate water. Well I pulled the oil on the bike yesterday including removing said tank to clean out the "sump", the area on the floor. Let it out on to a clean tray and immediately spotted several tiny bubbles of water and then a few larger ones, all told about 1/5th of a teaspoon. Those are imperial measurements...:)
But my purpose is to point out that I examined the tank carefully and noted RUST in the seam of the tank on the bottom. Washed out fully and
scraped at the seam with a scribe and put in some phosphoric acid 45%. After a day almost all the rust is gone so by tomorrow hope it will
be 100%.
Just noting this as a reminder for those of us who live in a cool climate.

I have drilled the intake spindles on every Norton I have owned and eliminated the external crossover.
Then I use the extra hole in the head for an oil pressure gauge.

Hi Jim.
Please what you mean for “drilled the intake spindle”?
It means to enlarge the little hole that goes into the rocker?.
In case, what is the new measure?.
Please, what is the crossover to br eliminated?
Thanks.

Jim is referring to the topic of drilling through the ends of the inlet rocker spindles. By doing this, you only need an oil feed to one of the head banjo fittings, the oil will travel through the inlet spindles to the other side of the head and thus feed inlet and exhaust rockers on both sides. Doing this means you do not need the standard oil line that connects the left hand head oil feed banjo fitting to the right hand one.
As Jim says, he then uses the redundant banjo fitting to connect an oil pressure gauge.

Even though I do not really fit into that definition, you are right, it's just a matter of choice.

May be using a" lowerheat from friction oil" as per Jim's specs, will help too.........??

I actually think that’s a very good point. It’s easy to become over focus on the pressure figure, and perhaps we should place equal emphasis on the heat from friction figure cos if that heat leads to the oil breaking down, you’re not doing yourself, or your engine, any favours.

Hi Piero, Jim’s video should explain all...

What does that have to do with Nortons and an oil cooler? Let’s stick with apples to apples.

As far as I know XS1100s here in the US ran oil coolers.

Only when we the riders fitted them.
