Hi All

New on here but have been reading a fair bit.
I would have thought I could find the answer by search, but hours later I can't find a direct answer to this question specifically for this model bike.

I picked up an almost brand new L1 by luck, was buying another bike and guy had it in the garage, he bought it brand new, never rode it, factory stock, in perfect condition, so I made an offer on both and he accepted, so ended up with a gixer at a bargain price.

I have ordered a pair of slip on mufflers for it, just the cans and link pipes, cat stays, O2 sensor stays, butterfly valve stays, and even the quiet inserts are going to stay in the mufflers. I just thought these particular cans are smaller, will look nice and close to stock, maybe a little more throaty too.
Question is, will it cause a lean condition on this model bike?

New to Suzuki so not sure. I have been with the Honda forum (still am) and 99% of guys on there would not bother with a PC and tune for just the muffler/s. I assumed that the gixer would be the same, but thought I'd check.

While I'm on a roll, I'll hit you up with another two questions.

I installed a lamba eliminator on my CBR to get rid of that annoying throttle chop, or as I think it is called here the huky jerky, it helped a lot on the Honda. The gixer doesn't seem to be as bad in that respect, but I do know it works the same way, the extra fuel by tricking the ecu smooths out decel, and if I ever have someone on the back, no more helmet clonks.

So the questions are:
Is it worth doing on this model bike? Does it help as much as it did on the Honda?
If so.
How hard is it to get to? CBR was just a question of taking off the seat, unplug the one the O2 sensor is wired to it, and plug in the trick one, done in less than 5 minutes.
I believe the Suzuki is under the tank, on the firewall? How much do you need to remove to get to that?

Thank you in advance for any replies. Looking forward to reading more on here and learning more about the bike.

No one here has installed mufflers only on this bike?
Can anyone tell me how hard it is to get to the lamda under the tank?

seems to run well and no FI light, so assuming not too lean?

Unlikely that slip-ons will affect the fueling, particularly with the cat in place. You need a full exhaust for that.

Hurkey jerkey here is generally associated with the TPS acting up. I'd think the slipper clutch would handle what you're talking about. I'd be inclined to leave the sensor in place as removing it is going to affect fueling.

Slip-on only shouldn’t have that much of an effect. Remove the catalytic converter and you may mess up the fueling

 

[TwistedMister]

if anything at idle it would richen it up as air cannot pass as easily, back pressure, nothing noticeable tho

Thanks Mate, seems same deal as Honda, its still pretty quiet and feels like it's actually pulling a little harder off the bottom now.
How hard is that O2 sensor to get to? That throttle chop around slow corners gives me the sh**s! Need it to stop cutting all the fuel, but not sure if the hassle to get under the tank is worth the reward?

Yeah, seems to run well.

^Download the service manual. It's easy to get to after you raise the tank but you need to unplug the right connector. See page 1K-12 or search for HO2 sensor. See 9A-2 for it's location in the wiring diagram.

thanks, will do, how long did it roughly take you to get to it?

 

[BillV]

^My K6 thankfully doesn't have one. Five minutes if you're referring to the connector.

yeah the connectior.
5 minutes to lift the tank?

 

[BillV]

Depends on how long it takes to get your tools out but with them out the tank should go up in less than five minutes. Maybe more if you've never done it before. You probably have to first remove the seat.

OK thanks,
Thought it’d be a bit more complex than that.
I assume that the O2 sensor in the gsxr is only for low rev / low throttle opening for emissions same as any other manufacturer?

"annoying throttle chop...I do know it works the same way, the extra fuel by tricking the ecu smooths out decel...no more helmet clonks"
This might be the same thing and an alternate, possibly better, solution.
