New RC51 Owner

Hey all, finally got the bike I have been wanting from quite some time now. I had been riding my FZR600 for the last 10 years saving for my next bike (RC51). Purchased a 2004. I have a few questions:

1. What are the two "knobs" (look like tie down points) on the top of the rear cowl.

2. Did the 2004 ever come with a rear huger? May I saw looking for my bike had silver ones. The bike I bought does not and I thought it would be nice to have one to protect the shock from all the road material kicked up.

3. Was thinking about plugging the vacuum line to the flapper valve but could not locate it. Is it inside the air intake? Is there a simple way to disconnect and do I want to even do this?

4. If I do #3 do I need to re-map to take advantage of the better response?

Thanks guys I am so stoked about having this bike you have no idea!

Affectionately known as "Frankenbolts", they are for tie down cargo.

2. Did the 2004 ever come with a rear huger? May I saw looking for my bike had silver ones. The bike I bought does not and I thought it would be nice to have one to protect the shock from all the road material kicked up.

These did not come stock with a hugger

Look on www.rc51.org for detailed removal instructions.

A PCIII and a custom map is recommended no matter what you do.

Thanks guys I am so stoked about having this bike you have no idea!

I suppose if there is ANY place that is true then it is here on this forum. I am not a new rider BTW I have been riding since I was 13 (in the dirt) that would mean I have been riding on and off for 37 years!

Hey what about my questions guys? Any advice for me?

Thanks ok I see them there now. I had looked on the RC ORG WRT the flapper mod but its not clear to me what needs to be removed to gain access to the line to disconnect. I have downloaded what I think is the manual to see if I can find an exploded view. What I see on the bike is not what I see on the RC51 org view. I think the airbox needs to be removed or part of the housing???

Hey nochain, madbuyer is right on when he says PC111 and appropriate fuel map. It will really smooth the engine out. Pretty big difference in how the bike feels.

But you should do the flapper mod regardless. The flapper was a noise complience thing. That was the only purpose, to help quiet the bike a little (as far as i know). I really don't think it makes any difference in the noise level, imo. It's pretty much useless for our purposes, hence the reason everyone does it.
The vacuum line you're looking for is right on top of the frame/snorkel under the speedo. It's as easy as pulling the vacuum line, and block it. And the cap. But you should at least remove the actual flapper inside the snorkel as well.
The whole mod, done right only takes about 1-2 hours.
Even less if you're a madwrenchtwister-like madbuyer is

The airbox doesn't need to be removed.
The line is right under the speedo.
You remove the flapper from the front of the snorke/frame.
I just reviewed the RC51.org. I printed it and followed it, found it to be nuts on for my when I did my mod.
Important: you have to put the Baro sensor back in place and connected. figure 2
They dont mention that, and if you don't, you'll get Fl blinks when you start your bike.

There are two ways to go to simply disable the flapper valve.
1) Disconnect the vacuum hose to the flapper actuator, either at the flapper actuator itself, or where the vacuum line originates which is on a hose fitting located on the front throttle body.

Be sure if any vacuum line is disconnected, to plug that line or hose fitting.

2) Simply disconnect the flapper actuator solenoid connector attached to the left radiator on SP2.

The engine merely supplies the vacuum through a one-way check valve and held in a vacuum storage tank. The solenoid is activated by the ECU, which opens allowing the flapper actuator to be actuated.
