So, in an effort to promote the 0-160mph performance of the Superbyke, I am going from a 42t rear to a 45t. I don't do much sustained riding above 160 but it would be fun to get there quicker! Seriously, real low gearing on a 460 lb Busa ought to really feel lively, it'll be fun.
Anyways, after removing the rear wheel for the sprocket change, I inspected the Carrozzeria bearings (3) and below is what I found on the sprocket carrier hub! I caught it JUST PRIOR to catastrophic failure. What's the lesson? Don't ever change out a tire or brake pads without doing a serious inspection of your bearings! Dry ,schrapnel imbedded in the race and missing at least 10 ball bearings for me. Something tells me that the below blowout bearing WAS NOT Japanese, German or USA produced(read between the lines here). Picture what could have happened, driving hard, 80 mph, banked sweeper, heavy throttle.....then BANG, it lets go....I'm just saying....
Thanks to Scott (Isiahstites)we ordered replacements (Japanese, not Chinese) and for less than $100 bucks, it'll be tite, rite and better than before. BTW, he also ckd on ceramic bearings and the over $400 dollar price tag convinced me to say, not this season. Next time, for sure. I'll post how the bike feels with the low gears. Doyle
