Ya that's kind of my point , just running a little higher final gearing won't automatically mean the gears will go out x amount faster,if that was the case then across the board 5th's would only go out and then 4th. I won't say it isn't going to have a little effect on it, just not as much as other influences. Raptor 660's had a shitload of first gear failures. From what I've seen the oil condition(type,viscosity, mileage run,ect..). has more influence besides plain and simple poor material design and surface treatments plus which ones get used the most. In the Dr 3rd gear blowup thread there seems to be an awful lot a Motul brand oil use by those with issues, but simply no way to say 100%- This/that IS what's causing it. Even the Nova headsets are showing spelling now in 3rd.
