I`m sure it was asked a thousand times (BUT) i would like to know how you determin the perfect tire pressure for the gen2 with PR2`s (yea i just bought 2 just before the group buy) I was talking to a buddy that runs a BMW K1100LT & he said he does the 10% rule for his tire pressure (meaning the tire pressure goes up 10% after riding for an hour) i`m 225 ride solo & run front 8-8-2 lines & rear soft & 4 clicks

Tire pressure is so subjective.. I don't think you're going to find a consensus here really. :huh:

However, I think everyone would agree soft isn't a popular setting for the shock ;)

So you would put the spring preload on hard & how many clicks out

 
10% is an interesting number to know regarding how it gets higher when riding....

....but you should still check/fill with cold tires.

 
I run the preload to the max.. no clicks left. I tend to ride pretty aggressive (when I can ride, my damn body keeps bustin' up on me :blink: ) and the stock shock is rather bluesman wimpy :lol: So as soon as I can afford it, that unit is gone. :bye:

A lot is going to depend on how hard you ride, what sorts of roads, how hot it is, and a host of other factors.

For tires, I run Mammy Yammy's spec (39/42) for most of my riding, which tends to be longer distance touring. This seems sane. If I expect to be loaded light and doing twisties, a couple pounds less. Works well for me, and I got pretty good mileage out of my first set of PR2's, and so far so good on the second set.

As far as suspension goes, I'm about 40-odd lbs lighter than you, and I run more or less the Jeff Ashe settings (see Bin 'O Facts), and set HARD and dial in a bit more on the rear if 2-up. Again, it is very subjective, but if you start from a baseline like Jeff's settings and then tweak it up or down from there you may eventually find Nirvana.

Hope this helps.

5' 10" - 195# - 20# plus tools/spares in right hard bag
shock always on "hard" preload

40# front 42# rear on PR's

just my 1.5 cents
Cent and a half? Damn Mike, you overdid yerself That kinda wasting of brain power (a full cent) is most certainly causing you some serious head pain right now.

I suggest no thinking for a least a week..

:****:

Once the tires are broken in , i`m going to try it (got to have digital guage for best results)

Of course i always check tires before i take off & cold of course.

42/42 psi, regardless of tire brand.
On straight roads perhaps.

On cold days on curvy AR pavement, it might behoove you to reduce the front tire pressure.

I had 42/42 when I went down in AR last fall. The major problem was me entering too fast...but the front did wash out unexpectedly...so I think tire traction may have been a factor amongst other things.

As someone said ...Ashe maybe or someone else...you don't want a stickier back tire than a front tire.

I had a RS rear. PR2 front. Bad combination.

42/42 in mid 30s temp. Looked back to check on the gang behind me...didn't see the corner speed signage...over cooked the corner....tried to ride it out (ie lean more)..what happened next didn't feel too good as the front washed out.

So yes, 42/42 on desert/interstate highways. Maybe adjust some if yer doin' AR/MO, SE OH, WV, or Deals Gap....

'Course this is NEPRT...so take my comments for what it is worth.

Exactly correct.

I keep my tire pressure at these levels regardless of the terrain, and lemme tell you, we have some roads in California and the Rockies that make a piddley little 11-mile Deal's Gap look like a warm-up lap.... and I don't have any problems running these roads at a right lickety-split manner....

39.534587 PSI front

41.874568 PSI rear

this is at 65F ambient temperature at 4,258feet elevation.

Of course I never use this pressure at dusk, that goes without saying.

That's it. You've convinced me. ;)

Forget what I said.

42/42 everybody. :clapping:

Could you get a little more precise. :rolleyes: There are still too many variables.
