True enough @mototrek, I was playing the role of stunt rider on Paul’s bike for those shots as well as setting it up with some of the tuning components mentioned in this video 😎
I get the feeling that Mike could deep dive into a lot of this, but still managed to keep it quick and understandable for everyone. That's a very impressive skill to have. When I meet people in life like that I listen, as they are usually the masters of their craft. Well done.
Hi. Just stumbled into your channel. Fantastic content with really high quality. Started tonight watching from the the first video over 3 years ago. About to get an adventure bike and this is my new bible.
A very very well and detailed explanation, especially for the technically not adapted viewers! #trustmeimanautomotiveengineer Stay healthy guys and greetings from Germany 😉🤙🇩🇪
You do NOT want to tune to Stoich for power or economy. Stoich is only for emissions reasons. If you want power, you tune rich (~12.5 or 13.5:1). If you want efficiency, you tune lean of peak (15.5+:1, as far as you can, before power drops off more than fuel consumption, all the way up to around 22:1, where the combustion starts to fail, entirely). Running THAT lean does NOT melt anything. In fact, the engine runs hottest at stoich, which is not good, at WOT.
Pretty accurate. except on these types of engines misfires occur around 16.5:1. To get 18:1-22:1 to run would require more induced inlet turbulence, better quench area (in trade for valve area) and smaller inlet tracts. Economy is a toss up - as we mostly want minimal RPM - as it's number one driver for mileage. So often making more power with more fuel rather than too lean - but at low rpm yields best economy
Is it possible that the factory mapping could develop a glitch on a NEW bike with only 1900 miles, and cause the engine to knock ? Could mapping cause knocking in any way?
Great content. I really enjoy the subjects you guys address. Have you ever done a tutorial for off-road/adventure riding 2-up? Great subject no one addresses. My wife and I 2-up a lot and it has its own challenges. Thanks for your time and keep it up!
You mention at 4:22 that you can flash the ECU to accommodate the mods you've made to your intake or exhaust. I thought we were focusing on correcting the problem of bikes being underfueled by design, not correcting fueling after mods. Did you digress or is it supposed to be a given that you need to modify your intake / exhaust to get any gains from any of these solutions? Could you clarify for us novices?
Hmmm interesting video with more interesting comments, back in the 1997 EFI was introduced on the BMW R1100GS range, we had a brand new one in the workshop, and started bagging out the EFI issues it would have and how unreliable it would be.....well I bought a new R1100 GS in 1998, and had done 350,000km, it was common that the hall sensor on the timing plate would fail at 150,000km, and that's about it for EFI components that would fail, apart from a injector clean at 200,000km and replaced the throttle bodies as they had worn out...I did come across a rider with a R1150 GS that was running rough as he had fallen off the bike and moved the TPS with his boot, we could have reset the TPS if we had a volt meter. Now for Carburettors....diaphragms tear, floats become porous, jets clog up, but are easily fixed on the side of the track or in the middle of nowhere if you carry the odd small parts. New bikes you need a magic black box to adjust the mixture, old carbie you need jets or just a simple change in the needle position.
I have EFI on my 91 K75, Rob, and it's still going strong after 190,000 miles. Of course I had to change out the rubber bits in the fuel system. Hall sensor is still good. I've adjusted it to experiment with the timing. - Tim
Sure. These ECUs are capable to do that too, depending on the mapping. There is for example the possibility to change the mapping of the throttle body, resulting the butterfly valve to open just up to 50% while turning the throttle into full lock position.
Unfortunately Power Commander do not offer anything for the R1250 GSA, and currently have no plans to do so. Unfortunately here in the UK so many re-map places are a rip-off so am struggling to know how best to get my bike tuned for the full (de-cat) system and end can.
Is it possible that the factory mapping could develop a glitch on a NEW bike with only 1900 miles, and cause the engine to knock ? Is it possible for the mapping to become slightly corrupt or would it right work or not work ? Could mapping cause knocking in any way?

14.7 is what the stoichiometric say. In real life, not all the fuel is burn so that is why we need more. However, every engine has is own sweet spot because no engine burn fuel exactly the same way.
Most people that ride these so-called Adventure bikes have way more power than they can already handle to begin with we got enough dummies out there please don't make anymore LOL

Loved it, especially the end animation.
Thanks for sharing.. brings a lot of insight on what's going inside.. 🙏
Thanks! Very well explained.

Excellent content. Thank You.
Very informative Tim, top video!
Glad you liked it, Stefan!
I just installed my rapid bike evo on mine. Mine is more to help smooth the bike, especially with elevation changes.
good stuff Mike

Good stuff. Expect an email asking what I can do to give my bike a unique personality.
Good day.. I just bought a falcon 400 cc.. there's a dead spot in the throttle...right after idle...can you suggest a fix for this
Very understandable English, thanks from India. Is Cassie with you?

Is there one that will slow my bike down?
deflate your tires... hahaha
you can change your sprockets with another ratio. it will lower the top speed, but add more torque.

LOOKS LIKE YOU COULD ENJOY A NEATO TOOL KIT... 😉👌🏼
Question, My scooter suddenly stop,then check fuse battery starter's fine,but won't crank .Is this ECU problem?

So... F.I does not automatically compensate for modifications as dealerships say? "Fit the pipe, the FI will compensate".
Depends on the bike, Marlon, and if the bike's ECU can compensate enough for the pipe you fitted.

At 8:53 did he say optimal AFR is 14.7? That’s lean and what they come from the factory these days. I bet he meant 13.2.

@@cedricboivin9422 I'm after AFR 13.2 :)
Personnaly I’ve never messed with efi so I may like even more
Richer is better 😂😂😂
@@cedricboivin9422 that's true
Yeah yeah, really. Electronic parts never play up ??
Low down , off idle smoothness can't beat a carb.
Power , fuel economy can't beat EFI
maybe you need a little more tuning - most people properly tuned will find opposite

Here is a challenge:

TC and AW always off.
Not a bad article, but maybe not a good fit for this channel. I come here for riding skills.
We know, Alan. Don't worry. Plenty more riding skills come up soon.
it isn’t all about you Alan...
Please don't tell me that carburetor is less reliable than all those electronics and sensors...pffff
but it is, by a large margin. i regularly have to clean and rejet my dirt bikes, and only rarely do i see damaged tps or air sensors. now, of course the carb is also infinitely more repairable, including quick fixes in the bush to get back home.
Reliable, maybe not, but does it make the bike a whole different type of beast, yes
FIRST. YAY
i got a Honda, and i would NEVER change the ECU on it nor reprogram it.
Ukraine kastum BMW 1956
Carburetors flawed due to being mechanically complex? WTF! :D
Dude if you run your bike at 14.7 to 1, you won’t go far
Oem bikes usually 14.7....
Not at peak power otherwise they would melt piston
