Currently bike is full exhaust and a Moore Mafia flash. I'll be adding a drop in filter as well as getting it dyno tuned. What else can be done to make a little more power out of these? Are there velocity stacks available for this bike? I figured maybe the gsxr ones would fit but wasn't sure. Point me in the right direction please!

You could have engine work done like porting, big bore kit, cams, turbo etc...but it doesn't make much sense on a what is essentially a budget big bore street bike. After spending all that money you could have just bought a higher spec bike to begin with.

Like Supercharger said there are nearly endless possibilities. Your budget and desire are the limitations. Turbo, nitrous, big bore, built motor are all possibilities. You are near the end of your ropes without putting serious money into it though.

As for velocity stacks. I don’t know if the GSXR stacks would fit or not. That said they usually don’t make that much power and really all they do is move the powerband. Shorter stacks will pick up a couple horsepower at the top of the rev range at the expense of power and torque lower in the rev range. I don’t think that would make much sense on a streetbike. At least not for me.

yes they fit and help the power delivery, even the hayabusa ones fit, the gsxs has two busa and 2 longer ones... the gsxr1k ones seem best for overall power delivery

ive returned to full time work so my engine project is waiting... but its not a cheap option it will be around $4k just to get a big bore piston kit installed for most here, but i think just the parts/ boring/nikasil recoating cost me around $2500

Hands-down, the most effective power modification you can do is replace your stock wheels with carbon-fiber wheels. The difference between CF wheels and stock wheels is at least several seconds per lap, and the acceleration between stock wheels and CF wheels is just ridiculous. And CF wheels impact all the performance of your bike, not just acceleration.

I would suggest CF wheels first over anything else; pipe, suspension, or engine...CF wheels come first. But they aren't cheap. They are, actually, really really expensive, like 1/4 of the cost of your bike.

This video demonstrates the difference between CF wheels versus aluminum wheels (although I'm sure that wasn't the intent).

This is not completely true.

I raced with stock and carbon wheels. And it’s not as simple as the media and wheel companies make out. It’s changes the bike. Yes for sure. Not so much in power/speed.

But you will have to add in things like. It will completely overwhelm the standard suspension. The carbon wheel moves much faster and responds to more bumps than a stock wheel. High speed damping takes a battering. The valving needs to be changed a lot to compensate.

As for power. Yes. The bike will be lighter. Roughly in a sub 200kg bike you could say 1kg equates to 1bhp. Very roughly. But unless you’re sub 70kg kitted. You’d be better losing weight from the rider than anything else is your looking to lose weight to increase power.

Handing will be a different thing. But on the road there’s now way guys are getting into the tilt times or going knee to knee to see the carbon wheels benefit.

We fitted carbon wheels. The bike was better. But overall lap time wasn’t better due to the fact the suspension tied itself in knots.

Considering the S1000 has a detuned K5 motor. Surely the most common sense thing to do would be to start with the K5 original R motor. With circa 180bhp. Rather than spend time and money to get a detuned motor back there. Then try to tune higher.

A GSXR K5 motor with cams and head work will give more power and be cheaper than reworking the S1000 motor.

Get one from a breakers. Build it separately. Then swap it and add a full system etc. Much more cost effective
