Decat

You are likely going to fundamentally change the A-F ratio by decatting and would be foolish not to have the bike remapped as a consequence. The question you really need to ask is why bother at all as the OEM system is already very good. That or do it properly and just fit a full exhaust system.

Re: Decat

Weeks of misery? How so. Mine is top class bar I slight hunt on idle

Dyno Power Run

The only way you will know if the fuelling is correct after fitting a full exhaust system, or decatting, is to take your bike to a Dyno Centre and conduct a baseline power run. Regardless of how you think it feels this will identify if there are any issues with the A-F ratio and whether you need to fit a Power Commander, or similar fuel management system, and have the bike mapped.

I do intend to get it dynod. It was lumpy until I used the full range then it fine out. Ill let ya know when i dyno it

 

[Maddogsween]

This is my dilemma.... to do or not to do.... no issue with getting it dyno'd and even putting a Rapid bike on her.... not sure what benefit I am gaining... I've always decated, but it's been a pretty straightforward job... never had to cut the stock exhaust as it was always in parts... the gp can sounds the nuts already.... so the question is .... remove cat= weight saving, better sound, better looks vs leave on= heavy bike, ugly cat(can be covered), no fuelling issues ... geez heads a mixer... my gut is telling me to leave it... I honestly don't need it any faster...

Sounded good to me - and it's causing you no bother...

 

[Corkgsxr]

Would fitting a rapidbike evo have any impact on warranty as it's not altering the ecu

 

[fast_ryan]

Warranty

No.

 

[Maddogsween]

So want the cat cover though can't find one for a 17

I sed feck it. I'm throwing on a rapidbike evo. Why not make the most of a class bike

 

[Corkgsxr]

Just realised when I fitted I never blanked the pair system. Is that needed to auto tune properly or does it matter

 

[alex]

Its covered to a degree in this;


but P.S. the flash option isn't available for the '17 S1000RR like it is for the Yamaha.

TL;DW: IMO EGR/SLS removal is great for absolute mapping on the dyno, but not needed on the streets.

 

[Corkgsxr]

to be fair bar the first few miles and pulls. it has alot more midrange.

donno if its differant or not but it pops blue flames now that its dark

Fuelling

That's a very good indication that your fuelling isn't correct and needs to be adjusted.

 

[Corkgsxr]

Re: Fuelling

Doesn't it need time to adjust. I done less than 50 miles

 

[alex]

There's parts of the rev range which can't see enough correction to fix. The stock ecu will only correct within a range. Where its leaned off for emissions it will never full recover.

Even with rapidbike at it?

 

[alex]

No i thought we were talking stock ecu alone.
