Ok. which bit of 'raced for several seasons without a problem' did you not get?
I am a fan of any engineering man / woman / company which produces something worthy of praise. I think Lockheed did a fabuolous job on the C130 and the Tristar for instance. I've worked on both, and been impressed by both. I think BMW did a very good job on their E34 and E39 models. Both impress me with their ingenuity and engineering know how.
Likewise, the NSR is very well built and is something which impresses at very turn.
Why do you think that on a closed throttle the engine isn't providing enough lube? I have personally raced at tracks where I held flat out in top for 30 or 40 seconds, followed by deceleration to a fist gear hairpin. No siezure.
How long do you think any bike manufactuerer would keep their reputation if they sold bikes which died within six months? Ask Honda, they made the VF750 with it's "chocolate cams". That hurt them - a lot - and they knew that to compete in a global market you cannot produce sub standard goods and survive.
Ask Norton. Or BSA. Or Rover. Or any number of manufacturers who've gone to the wire becase they couldn't compete. Except Harley of course, and I've no idea why they're still in business!
