Yoshimura RS-3 Install
Hey Guys,
I just picked up a used Yoshimura RS-3 slip-on off eBay. After I bought it I seen it doesn't come w/ a O2 sensor port in the mid pipe. Being that I have a 06 F4i my bike comes w/ a O2 sensor and it had a cadillac converter . I don't have a PCIII or the funds to purchase one and was wondering which route is the best way to go.
1) Install a Dynojet O2 sensor eliminator part #76423005 or do I need a PCIII to use the O2 sensor eliminator?
2) Drill out the mid pipe on my exhaust and weld a 12mm nut to screw the O2 sensor into.
Is there a benefit from doing option 1 over option 2?

not to step on your nuts... but please dont say "Cadillac converter" ever again..
its "catalytic converter"
I agree with Z.. get a bung welded the right way for a few bucks.. bring your stock mid pipe and have them put it in about the same place to keep the header to O2 length correct... they are probably heated..

Agree with weld, but you could also bypass it see my later post

Try a 330ohm resistor
The O2 sensor connection is located behind your right mid fairing
Insert into the bottom pins With the WHITE and Black/White wires

OK, I tried the resistor thing just for ****s and giggles. Once I put the resistor in I turned the key to the On position and my fuel pump didn't prime, so I didn't try and start it. Then I took the resistor out and plugged the O2 sensor back in and now when I turn my key to the On position my fuel pump doesn't prime, so my bike will not start. The only thing I did since the bike ran last was put the resistor into the O2 sensor and I took my front cowl off. Do I need to have my front cowl on for my bike to run?
any help to fix this would be great.

Well I found my answer from this post https://cbrforum.com/forum/f4i-main-forum-11/01-f4i-fuel-pump-not-priming-118984/
NickP123 said, you need your front cowl plugged in for your bike to run. So I ran back out to the garage and plugged it back in and low and behold my fuel pump primed
