Hey, Zippy, are you serious about thinking the Brit-made engines are better than the Indian ones? I ask because I thought the engine on my '02 bike (Brit-style engine but with electric start) was terrible. Inadequate lubrication system, terrible design of oil pumps and pump drive, fragile bottom end, prone to oil leaks, prone to burning the exhaust valve due to inadequate cooling, pathetic oil filter, unable to cope with sustained thrashing. I thought the AVR engine on my Electra X was miles better: proper gear oil pumps, twice the oil flow, proper head cooling, more robust bottom end, and much more able to cope with high speeds. I haven't got my new B5 yet, but from all the research I've done this is now Japanese-quality in terms of mechanical ruggedness, durability and design. Oil flow is almost four times higher than the AVR (almost eight times higher than the original), which can only be good. These are only by thoughts and observations, of course.

Thack - The short answer is an unreserved YES! However I must point out I am comparing a British designed and built engine from the late 1940s to the early 1960s, to a copy of the same design made in India from the mid 1950s until the end of the 1990s. The Austrian AVL engine of 50 years later doesn't come into it. What you are effectively saying is "My new Indian apple is better than the old British and Indian apples - because it is an fresh Austrian orange!" What I'm saying is that of older engines of the same design, the British one is better by materials used/machining and tolerances /design features used on the Brit engines that are deleted on the Indian copy (ie:- 2x oil pressure relief valves and 1 oil filter, just for a start....)
