Hi All, thanks for the warm welcome on the pinned intro thread.

I've taken the new girl to Sydney Motorsport Park.

The guys in the garage say we won the beauty contest hands down 😀

Anyway onto my questions and problems
1. What settings to use on track? I tried custom engine map with all settings set to race. Here I found that the engine would decelerate hard as soon as I let go of the gas. Check out session 1 to 4. I think sport engine mode worked best. I wasn't keen to turn TC off completely.

2. On the main straight I easily hit 240kph on my Kawasaki ZX-6R. Was passed easily by those bikes, even though I think my drive out of the corner was ok. Check out Session 6. Even KTM 790s were passing me!

3. Generally drive out in second gear is really weak. How do I stay in the powerband? Re-gear the bike? First gear feels too short and the motor stops pulling after 10k rpm only in that gear.

4. Is there a way to turn off all electronics completely or otherwise how do you use custom engine map properly. Even the engine braking settings etc? To feel what the bike is like raw, then dial in the electronics as needed.

Anyway apologies for any user error, I'm still struggling to gel with the bike powerwise and electronics. But the chassis - AMAZING!

Check out my YouTube channel where I uploaded these sessions.

• Session 1. Getting used to the bike. TC7. Was really holding back my drive out of the corners.
• Session 2. Almost lost the front. Leaning and braking hard?
• Session 4. Custom engine map. TC1.
• Session 5. Sport engine map. TC1. Amost achieved PB (1m59 using RaceChrono in my pocket...) benchmark set on my Kawasaki ZX-6R (1m57). All other sessions well above 2min. EDIT was actually 2min2 so still 5 seconds off personal best.
• Session 6. Sport engine map. TC1. 2min2. Ran wide on one lap.

Anyway, had a blast!

Here are some tyre comparisons.

My old ZX-6R on Dec 2022. Fresh Rosso Corsa 2.

F3 800 Yesterday. Same track. Though these are 7 year old Rosso Corsa 1.

Excellent question, what are the optimal settings in Custom Mode for track use? I use Sport Mode with TC at level 1 but plan on turning it off next trackday.

Your vids show that you are short shifting quite a bit. You're barely using the power band as peak hp is at 13k rpm. Wind it out, hit the rev limiter and you'll feel the difference as you keep the bike in lower gears especially on the straights.

Are you holding the throttle wide open?

 

[SupersportLove]

Hello!

Yes throttle is fully open, but you are right I need to hit peak power. I don't know why I'm so scared to push her.

I've tried waiting in first gear to get to 13k and looking for the shift light, but engine dials back at around 100kph or 10k rpm (I recall).

(After some advice and research) To make this bike work for me, need some mods. All hopefully before the next trackday. Plan below.

1. Gearing, -1, +1. I think on a 2015 that will mean going to 16T and 42T. 525 pitch since I cant seem to find 520 in Australia. $200 in parts.

2. ECU flash to remove engine braking + other stuff.

3. Suspension setup next trackday. I seem to bottom out when hard braking.

4. HP Corse high mount. More for sound and enjoyment. $1200. When funds allow.

My upcoming maintenance bills

• new tyres. The ones I am on are rosso corsa 1, 7 years old. $700.
• 24k service. $1200.

Any other high impact, relatively budget mods recommended? Also this is my road bike and only bike.

Cheekily, after all the basics above and add another $1000 I can buy a track ready GSX-R, ZX-6R or Daytona 675. Older models admittedly.

Hi Guys,

Update. Dropped a valve on my beauty.

2000km and 2 months of ownership. What a ride 😀.

Thursday, bought used high mount HP Corse

Friday, installed HP corse and -1T front sprocket. Quickly proceeded to melt the stock rear indicators, funny. These are track only pipes hehe.

Good ride on Saturday morning.

Sunday, drop valve on the way to favourite twisties spot.

Good points: learnt how to hitch a trailer, how to push a bike up a trailer ramp and strap down. I'm now a pro at parralel parking a trailer.

 

[esq'z me]

On No !!!
I hope you can get her repaired.

Dang

Was the service done before the valve issue?

Yes, but unfortunately it was just a minor service at 18000km before the track day.

Also, I didn't change the oil after the first track day.

Looks like the decision is made though. Wife enforcing sale of bike, not fix.

So I'm parting out the muffler and other things, and selling the remainder at a reasonable price.

 

[able duc]

Thats shit luck and a dam shame for sure was a nice looking bike. Will you pull it right apart to sell? or sell complete?

I can't even manage to secure 5k for it as is.

Thinking to go against wife advice.

Main MV repairer is Sydney is saying

• $15k for new crate engine plus labour vs
• $5k to $10k for engine rebuild

He says the engine swap to a B31 incompatible. But several threads on this forum say otherwise.

I'm still up in the air about all options.

I need to read up and link up with guys here who have done successful transplants

 

[able duc]

you'd buy an engine for a couple of thousand or keep an eye on the auctions for a crashed write-off
how do you know it dropped a valve?

One of my potential buyers brought a mechanic with him with a engine diagnostic tool. Error was timing fault or something. He agreed likely drop valve.

Which engine though? Does it have to be an F31?

Keeping it as decoration kinda sounds like a fun idea funnily enough. Buy a $5k gixxer to thrash at SMSP and wait for this.

 

[esq'z me]

The B3 engine and the F3 engine are basically the same. Cams and tuning are main differences. You can look at the parts catalogs and compare part numbers for all the internal parts. Crankcase and head are the same castings.

 

[able duc]

So with say ECU Studio you could put a tune into your f3 ecu and run a B3 motor?

Thanks guys the the advice and confirmation.

Local dealer mechanics I think are either trying to upsell me to a crate engine or have never done an engine swap.
