there has got to be something wrong with this thing.
I am 220 and have to hit a bump with my arse hanging off the back to get it to wheelie.

piston compression,
my z250 just seems low on power, Im checking compression to see if I need rings. (it starts up really fast and easy so Im grasping at straws)
I cant figure out why this thing is such a terd

but my brother has a wiseco high compression 10.5:1
here are his mods, im 16 and weigh about 165, and can ride a wheelie just as good as my 400ex.
CHM P-4R slip-on exhaust
DynoJet kit
Factory Suzuki swingarm skidplate
Polished & Ported head
PowerMadd handguards
ProCom rev box
Uni Air filter
Versha Valves
WebCam stage 2 cam
WebCam valve springs
Wiseco 10.25:1 piston
only one problem, theres too much power for the suspension and chassic, there are elka's to get for it though

do you know the psi it should have stock ?
my 250r was around 185 psi but it was a 2 stroke, Im not sure how close to that it should be.

high as 200, but normal reading would be 130 to 175
