Great! That's what I was hoping for. I'm planning to pick one up, hopefully its not difficult. I'm saving my nickles at the moment, I need a lot of them for that and an exhaust. I was also hoping to hear more about their version of auto tune as well.

The speedohealer is simply a percentage you enter. You ride it with GPS and then do some math. I did notice that their website claims to support the new 2015 model but if you can do it with the FTECU then no need to spend the cash on one.

I have 15 front (renthal) & 43 rear (talon) with a 520 chain. Acceleration is greatly improved & it will still make 180mph which is suitable for 99% of the European tracks.

The speed is registered at the rear wheel & not at the output shaft like previous models so no need for a speedo healer unless you want it to be 100% accurate.

I ordered up a 16-43 520 conversion combo from Superbike Unlimited last night... Justin and Travis give you some great customer service!

Thank you!

That's what I remember reading before. I actually did some digging and found the thread where I read about it earlier (post#37 in the thread)...

I have a 15T front sprocket waiting for me at the dealer that I'm going to pick up this afternoon.

 

[Squidpocalypse]

Anybody try -2 front? Renthal has a 14T front for 520 conversion. Thinking about trying it. It would be more aggressive than -1 +2.

I'm torn between 15/41 and 15/42 ?

Here you go

 

[JLeosnow]

I saw this option on my ftecu. I have no idea how it works compared to speedohealer...

This option in FTECU is only for disabling the speed sensor(not adjusting/correcting) and to be used when the bike is on a dyno.

And yes, the speedo is taken at the wheel so a sprocket change has no effect on speedo readings.

I thought about that too but since I'm going to a 520 chain I figured running a combo with more teeth on the front and rear sprockets should reduce the torque stress and wear on the gear teeth and chain.

I would think that would be a bit too much. These bikes are traction limited in the first 2 gears so I don't think going much more than about a 10% change would net you much more usable grunt on the street. On the track I'd say go for it!!

I just ordered the 520 Vortex kit from the mummy! I went with 15/43, and I'm really looking forward to change! More than anything so I don't have to be so easy with the clutch when pulling away from a stop light LOL.

These things have crazy tall gears but will this make them a bit wheelie happy.

 

[Doc Holiday]

Some food for thought...TJ at Riders Discount told me if I wanted 15/43 to actually get 14/40 because it would give me the same ratio but less chain so less rotational mass.

I'll take a couple of ounces hit in the weight department if it means the combo is a bit stronger and less prone to wear. On a 600 mid class bike I wouldn't worry too much about it. With having almost 200hp on tap I think it's something to consider....

I never trade low weight for strength...and I've got the scars and and X-rays to prove it!

We've run 14 tooth fronts on a few bikes making over 200hp. Quality chain, quality sprockets, and maintenance are key to durability and performance.

That is why they have such great wheelie control!

520 and up 2 in the rear. It's how the bike should have come from the factory.

 

[Carlos461]

I'm going 520 16/43 (0/+2). Vortex sprockets with EK 3D GP Chain.

I am running 16/43 now with renthals and 3d gp chain and I am thinking that I should go 16/44 or 15/41....>
