Triumph didn't get everything perfectly right, that's the thing! Changing things to make it better can only be a good thing.
This is why people have Boyer units, belt drives, hydraulic clutches, uprated oil pumps, uprated cams etc etc.
The lubrication system on OIF triumph twins, as well as most other British bikes, is barely adequate at best. Anything that can be done to improve it is worth doing as far as I can see.

TritonThrasher - In my opinion, based on a fair bit of experience owning, riding and tinkering with British bikes, they tend to wear out far quicker than Japanese bikes, or European bikes, or cars: can we agree on that? As far as I have figured out, the two main reasons for this marked difference are
(a) the high-performance engines such as T120, T140, Commando etc are overtuned in that they were based on 500cc engines in a far lower state of tune, then gradually enlarged in capacity and more highly tuned. The main bearings in a T140 aren't much bigger than those in a CB125 Honda, for example.
(b) Japanese & European bikes and cars tend to have proper oil filtration (not just tea strainers), together with better oil pumps (trochoidal in most cases), whereas British bikes tend to have virtually no real filtration and inferior pumps.
Despite these inadequacies, British bikes work very well when painstakingly put together with the best quality components, and looked after meticulously. When working to their full potential they are a joy to ride. That's why it is worth taking some trouble to improve them where possible.
It isn't very practicfal to do much about (a) unless you happen to have a full machine shop and a lot of skill and money. But where (b) is concerned it seems that there is scope for improvement without spending a fortune, eg: by using the best available oils, by filtering the oil better, and by increasing oil capacity to enable extended oil change intervals and better cooling.
I am not on an evangelical mission to convert unbelievers so I probably won't pursue this further. I don't really care whether others want to disagree for the hell of it. If they have something useful to say I'd be glad to hear it but I'm not into arguing the toss.
