Mods thread: Hyosung GT250R

Dunno yet, only had it done last week, haven't gone through a tank yet.

The extra power is certainly noticeable. All low-end/mid-range, much nicer for zipping around town, no noticeable difference to the top end. Dyno says it's another 10HP up from factory after the work.

JFK

Brilliant... Thats where I got my bike. How did you find them? Did they supply the air filter also? Can I ask how much it was all up?

Iain

[Gubb]

Yeah, they did the Filter and the Airbox. $480 all up including a service.

Thanks mate... Looking forward to the increase in HP. Did you mention any names when you went to JFK?

Just hope the weather improves so I can take it for a long ride...

Can't remember any names, but the main mechanic is pretty clued up (as you'd hope!) and a good guy to shoot the shit with.

High flow air filter means the engine can suck in more air, so you need bigger jets to supply more fuel due to the larger amount of air.

So i guess fuel economy would go down, but in my experience, re-jetting doesn't hurt the fuel economy noticably, i got 220km on the GN before rejet, up the mains and needle and i got 220km after.

So in theory, yes. In practice, not really

Well... sort of. You've got more air -- so you add more fuel. So now you've got more air and fuel. So, perhaps, at half throttle, you'll be getting the same amount of air and fuel that you used to get at half-throttle-and-a-bit.

So, you can see, in theory, it just shifts things around a bit. Unless you're running everywhere at full throttle (provided the engine can even suck in that much fuel/air -- you run into cams and valve work there), you won't use more fuel.

Could be a bent frame or a damaged motor perhaps.

I was in looking at the VFR that went yesterday and it looks pretty good might be a good one if you don't have a bike.

[CookMySock]

which brand aftermarket exhaust can has the best sound ? Has anyone put these side-by-side ? Some of them sound like a dog with a blocked nose barking down a huge drainpipe. Yuck.

I got a 250R and a 650R to change over.

TIA,
