Haha, do it, I wanna see what a $60k worth of time and parts turns a Super Moto bike into lol

My neighbor has a Husqvarna 450, will give it a try tomorrow

Whatever you do, try to resist the temptation of an SXV 550. 74 hp world's smallest production v-twin class killer from back in the day. Everyone will tell you not to do it, and everyone is right!

God I miss that bike. I set some fast times and walked some fast people on their fast motards. My wife and I even did a back-back trackday on it both of us riding it in different groups! All was right in the world right up to free practice on race day when it spectacularly exploded on the straight, dumped oil and caused 4 racers behind me to crash out of the weekend. Bad karma. Only two guys in the USA who can rebuild the engine (one of them in SoCal....)

Get the KTM 450 lol

Lol

but….I’m IN SoCal lol

She’s loud….started it up today to purge the cooling system….Also Jimmy made an elegant solution for two O2 sensors we are running, front bank and rear bank….mounted the plugins for the O2 sensors right next to each other under the left fairing using a CF bracket he came up with….so when we are street/track logging we can simply plug in the front bank for a session then the rear bank for the next session and get both banks individually tuned.

Wind that thing straight up going up Newport Coast Drive at 2AM. Get everyone acquainted with it.

Hahaha

some Karen’s are going to have ruined days with that exhaust….luckily most of the people in my neighborhood are gearheads and tolerate our noise lol

Keep in mind that the unpowered o2 sensors are going to get contaminated because they aren’t being pre heated by the controller.

There’s varying opinions on the subject… some say an unpowered sensor will .... it’s self if left plugged in the exhaust, others say it will at least need to be cleaned and recalibrated.

What o2 controller are you using?

Why not wire in another one to control the other 2 sensors?

Put me in the camp that says the heat from the exhaust is much greater than what is generated by its own heat.

The fouling occurs during startup from cold. Sensor has condensation on it that erodes the sensor if it isn’t burned fast enough.

Same goes for exhaust contaminants and rich fuel mixture.

It needs to burn off fast to protect the element.

we are setting everything up on the Woolich System, Woolich will let you tune cylinder by cylinder or by banks or all at once, BUT, it can only read one O2 sensor, so you have to move the O2 sensor cylinder to cylinder to do cylinder to cylinder tuning.

I don’t want to have to do that while doing street or track tuning so the compromise was to put one O2 up front and one in the rear banks, both in the easiest to access location should we have to clean or replace them, we then ran the lines to that place under the left fairing so I just have to undo a couple of Dsus fasteners and move the plug an inch over to switch from rear bank to front bank tuning.

we also routed the man logging port and the data logger up near the battery and will mount it for easy access instead of it running past the engine and up under the seat in the rear subframe.

as an aside, we eliminated the entire smog system and blocked off the SIS or whatever it’s called so no extra yucky stuff will be recycled through the exhaust system, that should help keep those O2 sensors from getting fouled, there will be less gunk to burn off.

we chose the two O2 sensors that grant easiest access, and once tuned we won’t have to retune that often….but I’ll have the option to if for example we find ourselves at a track day where the DA is unusually high on a really hot day etc

so pulling them to inspect or clean won’t be too difficult

[emoji106] loving your commitment to the project btw.

Fontana tomorrow, woot!

Woolich installed but not tuned, simply ran out of time. Next week we have a cylinder by cylinder dyno tune.

found a place to put the Woolich catch can

bike does NOT have a kickstand on it…the way we had to adjust it to keep it from hitting the exhaust it was going to rub the ground at high lean angles, so the kickstand comes off for track days, back on between track days.

had to butcher the lower fairing, because it’s for an Akra exhaust, will order a different lower fairing for it.

Looking good!! Flip your pitbull rear stand, much easier to put on and off while you have the bike leaned on your leg.

Keep us posted!!!!

Was an annoying track day, in some ways….

the good notes, the bike handled really well with the Pierobon Swingarm, noticeably less wheely on very hard pulls, and Fontana has area where you come off low speed corners and accelerate VERY hard up to 160 mph plus….the extended swingarm did not affect turn in or how the bike handled the whole turning cycle, tip in, lean, acceleration off the apex, all felt great.

the H20 radiator performed remarkably well, I had some problems on the bike that should have made it run hotter but the thing never got to 5 bars on the heat indicator.

we had a concern about the left can on the Spark WSBK exhaust, it looked like it was going to shoot 1550 degree exhaust gas directly onto the swingarm and my rear left foot!….but through some magic of engineering it shoots that exhaust gas directly BETWEEN my rear left heel and and the swingarm in such a way that neither my heel or the swingarm got hit from exhaust gas.

Spark WSBK Exhaust sounds epic btw.

another positive about the day in general was that Auto Club Speedway is both a very fast and very technical track, that’s not forgiving of mistakes in your line, or anything else lol, and I was there with my neighbor whose a great rider and patient teacher, and one of our Friends named Thomas, who, if he hadn’t decided to become a Veterinarian in life would probably be a professional racer, he’s for sure one of the fastest not professional riders in the country, and consistently sets the fastest lap times in the top group of whatever track day he goes to. We were also pitted next to Len, a 76 year old track dog who was a wealth of information and very helpful, between my friends Jeff, Thomas, and Len I learned Soo much yesterday, and despite some technical difficulties with the bike I knocked off about 8 seconds on my lap times from 1st session to last, I’m still slow, but I learned and improved ALOT yesterday.

Funny side story, Jeff has a cool little mini supermoto bike, he had my suite up in leathers abs showed me how to get my knee down on that little mini bike in the parking lot, videos are hilarious, several low sides but finally got my knees down….on a mini bike….in the parking lot hahaha

The negatives, the guys at the shop didn’t have time to tune the Woolich though it is installed, so they told me to just run it on the Akra map, which should be fine….but because the Woolich wasn’t fully set up I ran all day with the engine light on, annoying lol, but my shop said the bike was good and that the engine light was due to the O2 sensors but would run fine for the day…the engine did in fact run well all day.

But, halfway through the 1st session of the day my blip shifter stopped working altogether, no blip shifts up or down…the gear indicator on the dash also stopped working, so the entire day I had no blip shifter, no gear indicator, a new exhaust with a different exhaust note so I had to recalibrate the sound in my mind to know when I was near red line, then MANUALLY shift using the clutch both up and down on a track that has crazy speeds, and very technical tight turns and braking zones, worse, the glitch seemed to include ALL the electronic Nannie’s….so I had no ABS, no Wheeley control, no blip shifter, no gear indicator, no anti skid….learning a new track, as a new rider, on a 235 horsepower monster that I had to manually shift with no electronic aids hahaha….

had some pretty hinky moments. Tried a double manual down shift coming into the braking zone on turn 1 on the back straight decelerating from 150 mph and locked up the rear wheel…and there is a very hard acceleration through turn 20 onto the roval straight, without a blip shifter I was clutch/throttle shifting and trying to rev match from 40 mph to 150 mph with no wheely control and poor clutch control for a few sessions, if the Pierobon swingarm hadn’t have been on there my front wheel would have been pointing at the moon on those WOT upshifts, was a bit hinky even with it.

being a new rider, on a very fast and technical track, riding essentially a WSBK bike with no blip shifter or electronic aids is not the best scenario….also a bit annoying to have the bike in the shop for a month, spend an absurd amount of money to get a bike delivered that looks like a piece of art inside and out, that’s fast as hell and handles well, but that’s lacking BASIC functionality lol

I eventually stopped trying to go fast on the straights, and tried to salvage the day in terms of learning….what I mean by that, is I’m too new of a rider, and with no need on a properly functioning modern bike, to spend my day trying to learn how to clutch shift a 235 hp Superbike and handle it with no riders aids….when I’m still learning the basics of bike control lol….so I started just cruising the straights so I could be in the right gear and not worry about shifting and braking right in very fast technical braking zones and spent the second half of the day just working on my cornering….i eventually got to the point where I was Corning as fast as the fastest riders in my group, but then they’d blow by me on the straights where I just cruised to set up for the next corner. An odd flip in circumstance where I’m usually the slowest in my group on the corners and fastest in the group on the straights.

so positives and negatives on my personal development and the bike for the day. I can clutch throttle shift better at track speeds lol, though that’s not an important skill to learn on a modern bike, I learned I can handle a bike with that power without electronics, at least enough to recover from a mistake and not kill myself. My Corning did improve dramatically.

the negatives, I have a $150,000 bike that was at the shop for a over a month that rides like a 1990’s WSBK bike but with way more power than any of those bikes and might be a death trap lol….so that needs fixed right away obviously


I took the fairings off and checked every connection, looked for any obvious burnt wires etc…saw nothing, so I think the problems were software related or some wires ran wrong somewhere.
