The Suzuki Hayabusa GSX1300R Modified, Fueling Spot On
The Suzuki Hayabusa GSX1300R was with Suzuki for some repairs for less than a week, but the shock to the system of getting back onto it after riding a scooter and cracking open the throttle was still pretty immense. I don't think I could ever get bored of the Suzuki Hayabusa's engine!Saying that, there's always room for improvement, so I looked at the Dynojet Power Commander, and agreed to take it, a good friend was helpful with fitting the Power Commander and spent a very productive couple of hours setting up a custom map for it. The fueling is now pretty much perfect throughout the rev range and at every throttle opening. Throttle response is significantly crisper than it was previously, and this is particularly noticeable at highway speeds in top gear where the lunge forward as you open the throttle is even more intense than ever.
There're also now a couple more Nm's of torque on tap, and peak power is up to 180 horsepower, just shy of the 190 I was hoping for. But I've got a full Yoshimura system waiting to be fitted, so maybe that'll let the engine exhaust just freely enough to get to the magic 190 figure.
With fuel costs going through the roof, and not being in a particular hurry for a change, I decided to see just how fuel efficient the Suzuki Hayabusa can be. Having ditched the restrictive standard exhaust with its strangling catalytic converter, and now with the fueling spot on, I spent several hundred tedious highway kilometers at a steady 110 to 130 km/h. Unbelievably, the big Suzuki returned an amazing near 30km/l. So if you want to save the planet get yourself a Suzuki Hayabusa and a really loud exhaust system...
The only other additions I have modified are a pair of very trick forged alloy levers. They were fitted in less than 10 minutes and look great, but benefits are more than just aesthetic. They're claimed to be unbreakable as their pivot design lets them swing forward out of harms way in a crash, and I've found that the wide, flat front faces increase the fingers contact surface area and really give the impression that less pressure is needed to squeeze the levers, so the brakes feel more powerful and the clutch easier to operate.
