Exup 1000

well i took the pump out, everything looked ok. replaced all the orings and housing seal. didnt leak a drop of oil or coolant while sitting there statically. turned it on to burp the coolant and started leaking oil. im guessing it has failed internally allowing oil to pass through to the weep hole. ...

took a look around the engine and didnt see any signs of dripping. the dripping is still present even with the engine off.

But it is tr...

Hi all, Thanks for letting me in. Im a Marine stationed in Japan and came across a 1990 FZR with just 13k kilometers. Im eager to get riding and tinkering. I guess my first order of business is the R1 caliper swap and possibly removing the rubber "restrictor" in the intake couplers (can't ...
