Throttle positioning spring

KPS Throttle Spring Busa Gen3 - Hayabusa Service Power-Shop

The original tension spring force of the GEN III Throttle Grip is much too forceful. With this special spring your throttle grip will be much comfortable to use As a result, the throttle grip pull is now the same to handle as the Busa Gen 1 and Gen 2. Attention !!! Installation Pictures shows...

I've been too darn busy with work. Going to start tinkering in the evenings this week so I can give it a review this weekend.

Hi mate. Any luck fitting the lighter spring yet??
Thanks

No luck yet. My company is short on manpower, so I haven't had a day off in weeks... Once done, I will give my opinion of it.

I installed the KPS Throttle Spring last week and have about 200 miles of experience riding with it at this point. Installation was straightforward following the instructions and it fit perfectly. The diameter of the spring wire is visibly thinner than the stock spring. I would say that throttle resistance is reduced by about 25%. Nice improvement over stock.

Mine doesn't seem excessive. Perhaps a few drops of oil down the cables would improve things.

I opened up the cable play and adjusted it again. Cable move free so lube is not the problem. Its definitely the throttle body spring. I just haven’t found a reliable source for a lighter one. I can’t believe nobody else is having this issue.
