This is more of a suspension problem and not a tire one. Have you ever set your suspension sag or adjusted the compression and rebound damping?
Never set this on the bike, before I screwed with the pressure and hit the freeway, it road like a dream, never a moment did I feel loss of traction, or even that a tire felt loose or wandering, it was like I was on a track, then I adjusted the pressure went on a good freeway ride, got off the freeway, a few turns and the back end felt like it was pulling alongside me, then never felt the same, until I decreased the pressure, this morning,
I dont weight very much so I think that made the difference, if you weigh a good bit, the rec pressures might be okay,
Pressures are pressures. Rider weight doesn't have any real effect on how you should set your pressures.
I hear ya on this now, I read many places that they wanted to know your weight, and if you were a big boy, around 250, then that should be taken into consideration when inflating them, but I hear ya, its more about your riding and set up, and tires
I run a pirelli diablo in the rear and dunlop sportsman in the front,
This could be another problem. You've got two different compound tires that act in two different ways, and operate at different temps.
Yes I can see this as a problem, but the front is still good and the pirelli is new, and came with the bike, so I cant see pulling the front and replacing it while I still have life in it, a lot of life, and before this weekend it felt dreamy, haha, almost to good cause it was making me feel more confident that I should hahaha,
acceleration was lacking as well, once I would twist on the throttle the back end would lift and I would lost tracking accelerating, that was a major difference,
The rear tire would just spin up?
It wouldnt spin, but it would not grab the road and go, very strange ( more acceleration now with lower pressure) it felt as though all the power the bike was spitting out was being loss by the rear, then when I would even it out, it was like I was on two balloons,
now with the pressure at 32F/34R I can feel the front grab like it used to, but the rear still feels a little tall/foamy/wandery, to the point where I want to push down on it so it will grip, (make any sense?)
So now self doubt climbs in, is it just me? Is it cause I took it on the freeway for a hard run, and did something? could it be my chain? lube slack?
it is almost back to the feel of before so I am leaning towards to much tire pressure, tomorrow I will know it 32/32 feels better,
here is some background, bought the bike in july, road it most of the month, just street no freeway, it was set up by a guy who just runs track for the initial test drive, then I brought it home, this month I have been riding more so I decided to do my full checks, saw the tire pressure was low, around 29ish in the front and around 32 in the rear, (around) so I pulled my manual and follow it, went on the freeway the next morning, it ran great, a little high now that I think of it, got off in milpitas, hit the foothills, then I made a u-turn started heading home and the bike felt wandery,
pulled over thinking I grabbed some oil or a rock or squrriel, nope, nothing so I just rode home, feeling horrible the whole way, making me not want to accelerate or even corner,
decided to take a corner fast around 30, it stuck but felt loose, road to work the next day, same roads I always take and they all felt slimy, like any moment the bike would just come out from under me, never even had the notion before,
