Same. I hope I never don't have a lathe again. Even though I'm the worst machinist in America :)))

@ I’m not very good either. But i love when my bit sinks deep and cuts some good chips. I bought a brand new 700 dollar Chinese lathe and instantly removed all electronics and motor . Then i bought a 2hp electric motor and welded a shaft onto the chuck shaft then fitted a new belt pulley and put a belt pulley on the new motor . Then i trued all the flat parts to get it rigid and flat and now it eats metal like bubble gum.

Thank you for this. Inspiring

While it is possible to play with cam timing on gogo’s bike, it’s not sometime that is easily reproducible for our customers and other SDR riders. As for tuning by EGT, it works great on turbo engines that run low timing advance under boost. Too low of ignition advance to avoid knock in a situation where excessive boost pressures are run will cause a reduction of an engine’s thermal efficiency. Spark fires too late so that less of the combustion energy is used to push down the piston and more of it is pushed out the exhaust in the form of heat. Monitoring that exhaust heat is a useful way to know when that situation arises. Basically it’s a good determinator of how efficient combustion in relation to torque output. For non-turbo engines running relatively high nominal spark advance values, EGT tuning is a less useful metric.

@ Yes you’re correct thinking back the most degree of spark advancement was 30<35 degrees. I know you can run a water methanol to cool the air charge and aids cooler combustion chamber so you can push more timing I don’t know if it’s possible to adapt to gogos bike I know on a drag bike the swing arm becomes a storage area for a plethora of things.

@@carloslopezcolon4387water injection is rarely beneficial in a naturally aspirated application. This is because the primary role of water injection is to lower in-cylinder temps by vaporization effects. The reduction in charge temp allows for more optimal ignition advance on high boost turbo engines that would otherwise have to run very little advance to an avoid detonation. Same goes with methanol injection which I’ve used in the past in drag cars. Tends to work even better than water injection since A) methanol is a combustible fuel (water is not). B) methanol has very high octane and C) offers very good cooling effects when it vaporizes.

Yes once the ecu is cracked, we expect to dive deep into the 990.

Amen. Somebody who knows ball. Better arm than 90% of our team including men.

I'm with you brother. Don't just hang in there, climb out. 👊

Engines can tolerate certain amounts of knock. Mild knock that occurs from time to time is generally ok but still undesirable. But repeated knock or more serious knock can cause pitting on the piston, broken ring lands and ultimately catastrophic failures. I don’t believe the rs660 has knock sensors. Generally they are only seen on flagship bikes with high output, high revving engines. I do plan to add support for the newer Aprilia models sometime next year. I’ve owned an rs660 for a brief amount of time. Really fun bike!

Yes everything we learn with this project will be applied to our tune files. Even more power without undue risk is the goal.

That's the plan!

Sorry, school was a bitch for me

Happy to hear it!

With “exothermal” in your user name, I’m not surprised!

You're picking up what I put down.

Thanks for that!

Thanks for this, it's sure to inspire more to come.

Excellent!

That's fascinating, thanks Yamr1m

Glad to hear it! Thanks for watching

Yes there is. The tune we are working on is more of a race tune. He's already got street tunes and his system is being shipped for a while now

Yes the OFT for both the gen 3 1290 SDR is available. Same with the gen 4 1390. You can find a link to our website in the video description 👍

My experience is the Gen3 hack took way longer than projected.

Steve, you complained in the comments section of the last video Gogo posted about us not having the SDR gen3 OFT available for sale when you wanted to buy one last year. So you went with another tuner who rushed their product to market. I’m happy to you did. I think that works out the best for both of us. But complaining about our customer service when you aren’t even a customer is a little weird. Doing things right take time. Sometimes longer than anticipated. Others waited for us and are quite happy they did. Feel free to peruse the SDR Facebook groups for evidence. Same with the Ducati v4 OFT. I will never release something that isn’t fully tested and ready for public use. There is a very real safety concern with motorcycle tuning and I take my job quite seriously.

@@shivhappens9200 This is the difference between rookie tuners who are in it for the $$ as a side-gig to their main motorcycle dealership/sales/pursuits, and people who actually understand how these complex electro-chemical-mechanical machines work and the potential control over them that can be optimized. Good job. Customers may be rather misinformed, unable to understand, and have specific goals they just want to speak into existence, but you as a tuner do not want to take advantage of their ignorance and make them guinea pigs for broken engines. There's such a thing as litigation and lawsuits from customers which can ruin your career, no matter how competent and understanding you are of the tuning environment, customers cannot be made to understand it. It can get to be a witch trails issue in law-fare.

It's a shame you had a bad experience with OFT Steve, I'd give them another shot if you get the opportunity in future. My experience with OFT's customer service was fantastic, Shiv was extremely responsive and he even chatted via private message to answer the questions I had. He gave an accurate shipping time, told me which method to use for the fastest service to my country and made sure I got it in time for my track day. The tuning process was extremely easy with a video tutorial to guide me through, and the tune itself has improved the bike immensely, 3rd/4th gear power wheelies are much easier, I'm picking thats thanks to the better fueling below 6k RPM. From what I've gathered in superduke communities my experience represents the large majority of people who have dealt with OFT, and I think this video shows Shiv's character quite well. I commend Shiv, Gogo, and Angela for doing this work, which I imagine will trickle down to improve all of OFT's Superduke tunes.

This is a great collaboration Gogo. ​​⁠​​⁠​​⁠@shivhappens9200 do you have a tutorial video on your OFT installation? I’m a potential buyer of your tune for the SDR EVO but I’m a little freaked out by the process as I’ve never fiddled with ECU tuning. A step by step video would be great.

The straight at thunderhill isn’t very long. So 149mph is the speed he reaches before he needs to brake for turn 1. It is not the top speed of the bike.

If you can hit 175mph with your SDR on the front straights of Buttonwillow, Sears Point, Thunderhill or Laguna Seca, I will buy you a Gen4. And no dropping bikes out of airplanes allowed.. :))

@@superduked33 challenge accepted, need some time to buy the bike and transport it to Laguna, if I fly on the plane with the bike inside is it counts?))

Thank you that's inspiring.

Sounds like fun. Our straights are not as generous

That's what a racing paddock is like every night. Take bites out of each other all day on track and all night around the fires, and find the best friends you'll ever know.

😂😇🙃

It's like a small pool filled with several great white sharks and several orca.

Agreed.

@@superduked33 I can't believe this is Angela's first appearance on screen. She's way more charismatic than either of us! 🤣

Not sure what next year has in store. But I do have 2024 4th and 5th gears in my spares right now... :)). They're definitely going into my Gen3 motor. Shiv should respond about the dual plugs. My guess is more sparks = more thorough burn. Cylinder temps is a great idea.

Big displacement twins have large bore size, that is, if you still want high rpm (piston speed limits, connecting rod force limits, all of that) which usually translates to decent horsepower. Trouble with big bore size, the flame propagation from the point of the spark to the extents of the bore takes more time. This is not really an issue with four cylinder 1L engines as such, even when they shorten stroke and increase bore to radical proportions. Going with a dual spark setup on a very large bore size will reduce the amount of time to get all that HOMOGENEOUS (😆) mixture burning, thereby increasing pressure sooner and optimizing burn.

@@exothermal.sprocket Exactly. I suspect the transition to twin spark also had to do with emissions requirements. To ensure a more complete burn with less NOx output. Also interesting to note that the timing tables for the secondary coil are similar to the primary coil except for high RPM/high load where they are very retarded (single digit nominal spark advance) vs the 25-35 deg BTDC you'd see on the primary coil ignition tables.

@@shivhappens9200 Makes sense as regarding emissions. For example, the new Suzuki DR-Z4S coming has dual spark added to it. That's entirely emissions related. So the secondary plug at high RPM/load are firing significantly later than the main plug, you're saying?

@@exothermal.sprocket yes, that is correct. It would appear that is an attempt to ensure a more complete combustion by staggering the spark events.

I get zero head shake with shorter trail.

Four seasons in, good for you. Most only talk about, dream about racing. Making the leap is a big deal. Takes courage voluntarily entering an environment where you know you'll get humiliated, at first. So, props to you. Also for recognizing going faster, at first, is about the bigger things. But after some time it morphs into being more about the little things. And then the super little things. ...Thanks for this response, its inspiring - and by that I mean it is fuel for me to make another.

100% agree on the strain gauge, which I have now. Still though, crude as it is, the obvious is obvious. Thanks for watching

OK, I'll do that. Thanks for your feedback

OMG don’t even worry. Derek dishes abuse out to me in never ending brutal fashion. He’s actually worse to me than I am to him. We met playing softball years ago. I’m the oldest guy on the team, so you can imagine the abuse. Motorcycles came later after he learned what I do. Then finally the tables turned on him for a change. I have years still before I make up the abuse deficit. :))))

@@superduked33 Because you and I are the same age I am feeling MUCH better now! Go get him! LOL

Good luck, stay safe.

Super glad it helped. I'll do more

Glad you enjoyed it, I'll make more

There’s more to it when you have time.
