Hayabusa gen1 to gen2 conversion from Greece

[VagelisBusa]

Sorry for my bad English
Hi
I have a Hayabusa 07 gen1 with 115.000 km and I decided to convert it to gen2.
I bought the whole fairing (not an original one though)
I have modded the gen1 subframe so it can fit the gen2 tail.
If anyone needs any help to do the whole mod dm me.
I haven’t any help so i would like to help others.
Before and after photos…
I think i will stay only in the fairing conversion only…

Welcome and nice introduction! Bike looks great!

Welcome,

Honestly, the gen 1 is the better looking bike between the two.

Glad you had fun and got it to where you wanted it though.

Chicks dig Gen II fairing conversion bikes!

Welcome along from a Kiwi in New Zealand, the Oasis of the South Pacific!
You’ve done a great job on the conversion,
Personally I prefer the Gen 1 shape… especially the tail section, but beauty is in the eye of the beholder as they say.
Is it just the tail you are changing or will you do more?
Tell us about yourself and your bike history etc…. I see your bike is in a car parts Auto store, is that your shop?

Hi
Thank you so much
Well,
It’s love from the first ride as they say
A close friend had a gen1 5 years ago and when I sat on it I knew what i had to do…
Back in the day i had a Zx6r with dynojet upgrades and a gsxr 1000 k8 but they didn’t fill the gap…
And here i am… I bought a gen1 hayabusa last December just because i like to do things by myself I decided to put the gen2 fairing.
Its a tricky thing especially if its not the original parts as it was mine.
It needs plenty of fantasy to make them work together .
And yes We run a family business car shop and car detailing center since 1984.
Thanks for the interest

Your 'bad English' is probably better than most of the members here lol.
Well, you've come to the right forum for all things Hayabusa, the amount of info on mods, maintenance, and sheer Busa indulgence here is staggering!
You will also make new friends here, pretty welcoming bunch of people on this forum.
Hey, are you going to fit Gen 2 fairings to the front of the bike?

I have already gen2 fairings if you see !!

Uhhh . . ok. lmao.
Silly me, I was looking at the rear end for too long and completely missed seeing the front end lmao!
Looks amazing, well done!
Did you use Gen 2 front and rear sub frames? Or just modified existing Gen 1 sub frames?

Front it’s from gen2 (and gen2 ram air of course)
Rear modified gen1 subframe with gen2 undertail !

Hello guys!
I have some news from the bike
I went to the dyno to flash my ecu and install launch control and a shifter.
Unfortunately the fuel pump died and I replaced it with a new one.
The result is 163hp in the back wheel (not really happy) and 13.2 kg torque.
I think i will replace the front sprocket from 17 to 16. What do you guys think?( I am running 17 40)

I say how does the bike feel when riding it?

The numbers look low for a Gen 1 with an exhaust on it but:

Dyno sheet numbers are just numbers...as long as the AFR is good and it has no hesitations or anything, I'd just ride it.

 

[sixpack577]

Mid 160's whp is normal for a Gen1 engine.
Low to mid 180's for a Gen2
(Both piped, flashed, and tuned).

A -1 front sprocket (or +2 or +3 rear) makes the bike alot more agressive/fun.
I do that to every chain driven bike I've owned, lol

Well, it changed a lot with no hesitations at all
I am thinking maybe i will re profile the cams

Thanks for the info!
The programmer said the exact same thing!
I will do that with the front sprocket tomorrow

If the bike is responding well, I'd heed the words of @sixpack577 and mine and just ride it.

Re-profiling the cams seems a lot of bother....changing out the sprockets will give you the best band for your buck.

Hi everyone
Last update
I installed 16 tooth sprocket so know i am running 17 40
For anyone wondering it made a big difference and i love it.
The only problem is that my chain don’t have a lot length for adjustment (i have a brand new did 530 gold chain)
