What is tuned? Fancy cuts, nice and shining parts and the marking on the head?
No, real tuning is mostly a better timing, nothing more and nothing less.
If the inside looks like tuning it does not say anything about the timings.

Novarossi has to sell a stock and tuned version so they can sell the higer price for a tuned version for those who want to pay more. And be real, the engine as it is today is not different compared with 20 years ago. Only new machinery and materials can make tolerances and the "fancy cuts" better and cheaper and the trend is to show new engines every year which must be better than previous. Only the fancy stuff does sell to a lot of people.

So far the Novarossi 35-plus-21 is loved by me and a lot of people arround me and it would be wise to go back to that concept. The smaller crankpin they used in the LC 35-plus and further on has created more pain than gain in performance, the current rods are more expensive and unreliable...
