Rebuilding GPR carbs, low pop off...?
I am rebuilding my 2001 GPR 1200 carbs. I tried testing pop off with the original gold spring as well as with the new gold spring that came in my rebuild kit, and I am getting about 35psi for pop off.... I am using brand new Mikuni 1.2 N&S sets...
I've tried changing springs and bending the arm and still can't get higher than ~35... I am no stranger to rebuilding mikunis.... This is however my first 1200PV to work on. Any suggestions or ideas as to why I'm not getting a higher popoff? According to the Mikuni chart i should be popping at like 85psi...
