Zounds - I've been Shazaamed again! My woeful grasp of tuning has been exposed. So, the way I understand it now: The gains to be had from the larger airbox are only relevant for a highly tuned motor which compromises mid-range and driveability for ultimate top-end. Don't want that, no Sir. I like my bike to be gutsy but friendly. The increase chassis stiffness is of questionable benefit, and even then only relevant to racing gods. Also, if the RCV211 and M1 like increased chassis flex, then so do I dammit! I shall loosen my swing-arm pivot bolt and triple clamps accordingly. Thanks Shazaam for another clear and complete answer to my questions. Guess I'll have to spend the my cash on some diamonte bar-end covers and illuminating tyre-valve caps. Hmmm - a velour seat cover you say? Thanks for including that excerpt Skidlids - that level of precision is so far beyond me I'd need to catch 3 buses even to check it out. All the best, Spinoli |
