32/34?
Book says (with stock C3 Pirellis) to run 34/36, and I always run 36/38 cold. |

While the factory may recommend those settings, it does not really make any sense on the street. You simply won't be hitting the same rates of speed on sometimes cold roads.
The front tire is way smaller than the rear and if anything needs more tire pressure to equal the amount of heat in the rear. If you don't want to believe me, take your bike for an aggresive ride on a warmer spring or summer day and then measure the heat of both tires with your bare hands: The front will be hotter than the rear at the same tire pressure because it is way smaller than the rear tire. Basic physics guys; heat vs mass.
I run 30-32 in the rear and 32-34 in the front because of this reason.
Since the goal is to have both tires at optimum heat and tire stickiness, tire tempreture is absolutely critical.
Sorry to be so "preachy" but I've been working on suspension settings, tire pressures and fork tube heights for over a year now with a race mechanic and this is what I have learned and what I have experienced.
I much prefer my Michelin 2ct's to the original rubber.

Oh, I prefer my PR2s to the Pirellis as well...but really, I don't ride hard enough on the street to have to be at "optimum" temperature. Track days, I drop my pressures so I build more heat from tire flex. On the street...I'm nice until the tires are warmed up, and ride within the limits of my traction and environment once they do warm up. I'd rather balance between treadlife, fuel mileage, and then tailor my riding style accordingly. And I suspect that's the balance that the factory was trying to strike as well. Setting it up this way, though, works just fine for me and for my tires.
And keeps me out of jail.
Or the ER (again). |

After market levers maybe installed incorrectly? I had a buddy who had his front end lock up on the interstate due to this. |

Ratbuell, I think were really saying the same thing. Where I live in NorCal the roads are cold and comprised of mostly 30 mph turns. Its difficult to get my tires warmed up at all unless I lower the pressure some. My tire wear still seems good as I spend more time on the shoulder and not the center part of the tread!
Anyhow, I've done some time in E.R. myself from a diesel oil spill and lowside and I'm sorry for your injuries. It is kind of sobering. And painful. Heal well and fast!
