Also, after extensive testing with pipes, we found the Novarossi 2630 to be the best! The pipes tested were, Mugen 2501, Sirio 2611, Novarossi 2601, 2602, RB 2604, Skyline VR12, VR12 Plus.
Thanks for the information

How long do the ceramic bearings last? Do they have the same lifespan or even outlast the ordinary bearings? Also, what benefit does one get with a bigger crankshaft diameter as compared to a smaller one?
