Bikes bogs when throttle whacked, wont rev past 9-10k
Hey guys i have an 02 f4i and i am having some serious problems getting it running right, the symptoms:
no auto choke ( probably unrelated )
very slightly erratic idle
when warm and idling it bogs / hesitates when throttle is whacked open
wont rev past 9-10k
things i have tried:
new fuel pressure regulator
new fuel pump / filter
new spark plugs
checked air filter for clogs
Does anyone have any ideas to test before i take her to the shop? Been messing around with this for around a month now and i really just want to get out and enjoy the weather...

Replaced the fuel pressure regulator and thats when i got these serious problems, i find it very hard to believe that the brand new OEM FPR is bad but maybe i should try putting the old one back on..?

The Fuel Pressure Regulator is a fairly basic device. It uses vacuum from the intake manifold to regulate the fuel pressure. I'd be more inclined to suspect a vacuum hose leak going to that regulator than an actual bad regulator. This would also account for a rough idle. It certainly can't hurt to put the old one back on though.
