Could someone verify whether the stock exhaust pipe is entirely made of titanium or are there some stainless parts?
Reason to ask is because the company where I intend to tune to PC5 needs to install additional sensors and they hesitate to make any welds to titanium. How have you solved this issue? In a perfect case the tuning should be done individually per cylinder but that would require an additional sensor in each pipe. Currently I can't see how this could be done without destorying the looks...

why do they want to do that? If you have standard ecu then a dyno isnt possible. If you have a s2 or 3 or reflashed of same then no sensors (o2) are required at all.
Headers are stainless and mufflers tit.
I believe TimR (on this forum) ran a PC5 wit full akros with a stage 2 ecu and was not happy with the results just pissed off he'd ruined the look of his headers.
As stated in the previous post without a stage 2 ECU or flashed ECU (there's a man in Germany who can do them) you can not tune the closed loop 0 to 2000 revs.
Save your money for a fast bike if that's what you want, I've spent north of 3K on tuning and the last Dyno readings were 89.3 BHP and 114 FLB torque which is pretty much the same as she came out of the factory.
Thanks for the reasoning! Wise words indeed... need to reconsider the value. Think I’ll start with cancelling the dyno applointment for now.
Altough, I’m not really after more power. Would though like to fix the issues with ”no go” at low rpm, uneven engine behavior at 2000 rpm and the fuel consumption.
If I understood correctly from the comments, below 2k rpm needs something done with the ecu. Does this involve anything else than deleting the O2 sensor? The shop claims they can tune the original ecu but the cost seems rather high (600€). The odd behavior at 2k is possibly related to this also?
The latter, fuel consumption, is a question mark. In daily use I’m burning 7 to 8 liters per 100 km. Compared to numbers I find online, this seems high. My riding profile doesn’t explain the difference. Any comments, what should be the normal average consumption?
Yes under 2k revs the ECU will adjust the fuel to run the engine lean, if you add more fuel with a Power Commander the ECU will lean the fueling off again.
Changing the ECU from stock to stage 2 should cost between £350-£500 so your 600 euro quote is about right but what are you getting do they fully understand the MT01 ECU and the closed loop (no disrespect to them) but the question needs to be asked.
Mine has been stage 2 cloned and I find no need for a Power Commander (although I have a PC111 which I have run her on, but not currently).
Stock engines with stock ECU will benefit from a booster plug as this cheats the ECU into thinking it is colder (adds more fuel) or you can get similar results by unplugging the ambient temperature sensor which is behind the headlight although this will put the engine management light on, but worth doing just to see the smoother running to be had by the booster plug.
Don't know about fuel consumption I just fill her up thrash about then fill up again:)
