You got an allen wrench? Lucky bastard. The metal wire is a helmet strap.

Thanks for the great thread! I just picked up a used 2012 (536 miles?!) to race this season with M1GP here in SoCal. They just announced the addition of a Honda250r class with a contingency program...REAL cash prizes for the podium finishers! I'm hoping that I can get an early jump on some of the really good racers (and those pesky lightweight kids) who I expect will start showing up once word gets out that there is cash involved. ;-)

That's the main reason I'm on a CBR...
FYI with Motoseries they combine exp/nov and pay 5 rounds (one of the 2 rounds per weekend)

I'm on a CBR because its fuel injected

is there anything on the fuel pump that would be protected by that baffle?

The top of the pump and possibly the float? The pump is directly below the gas cap. On my GSXR, when you open the gas cap there is no baffle, but you can see the bottom of the tank that's curved over the air box a few inches below the opening. There is no way to hit the fuel pump on the GSXR but on the CBR you could.

The fuel pump is pretty tall, I slipped mine apart to see where those hoses went to because I was curious. It turns out the black canister is a fuel filter. I can T into the one hose that has a port right in the fuel sump to gravity drain the tank if I need to. It is the inlet hose for the fuel filter. It is also the short hose without the rubber sleeve over it.



The black o-ring is where the pump picks up fuel from the outlet of the filter and the hole shown just behind it in the picture goes to the filter inlet.

Last night I also got the air box drain sealed with a cap; 3/8" or 10mm. The drain fitting has a rubber boot with a slot cut in it from the factory.




The pink hose is a part of the crank case breather and acts as a catch can. It is plugged at the end and I will leave it as is hanging above the belly pan. I will watch it and keep it drained if it collects oil.

Did some checking this morning and as I suspected if the fuel tank were to be filled to the top with no air space the evap vapor line would be flooded. As there appears to be no valve other than the purge solenoid which is down stream of the canister, the canister would fill with liquid.

Glad to see another cbr out there. I raced the cbr in WERA last year along with a buddy and will be racing it this year as well. There's a post with some video and pictures around here somewhere... Great bike but be prepared to get passed on any straight... And on a 250...you quickly realize if it ain't a turn, it's a straight vs. how it is on the bigger bikes... Not sure what region you are in but I'm here in the Southeast. Good Luck!
