Lighter throttle and smooth shift

[DING]

Guys, I've found two mods are pretty useful.
1. Bought a lighter throttle spring from Germany. It is 30% lighter than OEM spring and now i feel my busa has faster throttle response.

2. The K-factory shift stabilizer. After installing this mod, shifting is much more accurate and smooth. Specially when u downshifting from 2 to 1, it feels like every gear is nice and clear.

That shaft support looks awesome. Wonder if it'll fit a Gen 2

It will. I had it on my gen3 motor before I switched to my built gen2 motor.

KPS Gaszugfeder 30% Leichtgängiger Busa Gen3 - Hayabusa Service Power-Shop

Die Original Zugfederkraft der GEN III ist beim Gasgeben viel zu kraftaufwendig und auf Dauer ärgerlich. Mit diesem Umbau wird die enorme, ungewohnt kraftaufwendige Gasgriff-Zugkraft um Etliches ( 30 % ) reduziert. Dadurch ist nun die Gasgriff-Zugkraft nahezu gleich zu handhaben wie bei der Busa...

Did we have that link as well?. I know that Shop that's KPS. He's the bomb.

Thank you I got the other link as well. They owe me some money. I've got some buyer cash to spend with them. Webbike solid.

Love that seat! Where did you get that?
I have a white Gen 3 too.

Also, it looks lowered and stretched.
How much did you lower the bike?
How much did you stretch it? Looks like about 4 inches.
Did you add a new swing arm or use an extension kit?

Sorry for all the questions, I love the look.

Yes, i did lower the bike.
1. I lowered about 4cm in the front, And 3.5cm at the back. U could llower more if u want. Coz we have bad road here.
2. I bought a 2inch-6inch extended swingarm from Evilswingarm. My current bike are using the last hole which is 6 inch extension overall.

Talk about the seat, the idea is from Sammy Cover. U can Google search "Sammy cover hayabusa", they have some very nice looking seat.

Indeed, but the throttle feels much better

I like the idea of the throttle being lighter but that looks like a PITA to change. Is it as bad as it looks?

After reading this idea I went out to the garage and twisted my throttle a few times. A lighter spring would make it easier but I’m not convinced it’s worth the time and expense to install.
Plus I want to make sure the throttle closes all the way when I let off. Maybe a weaker spring would cause a problem with the throttle not closing all the way.
Just my opinion

 

[Gen3lover]

Can I ask one more question- where did you get those carbon fiber frame covers?
They look great.

 

[Spudley]

I've torn apart two generations worth of throttle bodies, plates and all and replacing that spring is not at all complicated. Disassembly with attention to detail, reassembly with the same attention to detail.

Besides Paul put pictures on the website.

I already have this lighter spring installed. I am very happy with the result after riding for like a week. I am pretty sure the throttle will not closes all the way when u let off.

The installation process is not that bad. All u have to do is u gonna have to remove or lift up the oil tank, then u are good to go.

Lift up or remove the oil tank, then u r clear to replace the spring
