my bike may be broken...
problem is that if the piston hit a valve, it also (possibly) does damage to the rod, rod bearings, etc. All that would need to be inspected (if the dealer is doing it "correctly")
if it was just a light tap and tweaked a valve, the piston/rod/bearings are probably fine, and you could probably get away with just replacing the bent valve and the coresponding valve guide, and having the seat resurfaced. If you do have it apart, look for any sharp edges from any contact with the valves on the piston crown. Those high spots become "hot spots" reeeal quick once it's running, and that can cause pre-ignition, etc, and do more damage.

it's highly unlikely i'll be taking this bike apart myself. i bought it new specifically for the warranty, i'm definitely going to utilize it.
if for some reason they don't cover it, then yeah i suppose i'll have to fix it myself. there's absolutely no sane reason it should be denied repair under warranty.
i wouldn't even be upset at all if the fucking dealer was local...

i was always under the impression that engines were designed to perform within that range with no ill effects, no matter how many times you take it near the limit... as long as you didn't go over the redline (which i still think i stayed under, even if it was just barely under...)
the redline is there for a reason, right? don't go past it and you 'shouldn't' fuck anything up. if the engineers expected engine damage at a lower speed than redline, then why the fuck wouldn't they lower it?
maybe i gave the impression i beat this bike up all the time. i don't. or didn't, at least. i just expected that when i decide to take it close to the manufacturer's suggested max engine speed every now and then, it wouldn't bend a valve. at least not with 1200 miles on it.
at this point i will concede i was very mistaken about the build quality of the motor. i did have more confidence in it, or i wouldn't have 'taken it to redline all day'.

skroozloose, thanks for the attempt at a conversation, apparently i was also mistaken about my confidence in the intelligence of posters on this board. there is no excuse for that, it's happened to me too many times.

I wasn't trying to knock your bike, and I can say whole heartedly that what I stated about "quality" was from nothing more than experience, and not a cheap shot or any "brand loyalty" kind of thing.
it would be nice if ALL the companies out there were building quality product, but it's unfortunately not the case. I completely agree with your reasoning about the redline thing. It SHOULD be able to handle it, but alas, that's not always the case. The Hyosung is actually a sound design (albeit not thier own design) but in an effort to increase profits, they let some quality slip (read: cheaper materials).
"they don't build em like they used to" kinda thing, ya know?
In any case, I hope you get it fixed and back on the road ASAP. No one wants to be bike-less with warmer weather on the horizon. If you need a hand with anything, feel free to ask.
if you've seen me post before you should be familiar with the way i react in certain situations.
i'm pretty sure you're not retarded, and technically i didn't actually 'call' you retarded...
as you can see i'm a little upset about my bike being broke. fuck, every time i look at it now i get pissed off. i just want to get it fixed so i can go through the whole break-in process again on an already underpowered bike, and never take it past 9k ever again.
and the only help i think i'll need is a way to get the bike to the eastern shore. obviously i'm not trying to ride it out there...
anybody got a trailer i can borrow? promise i won't call you retarded...
felt i definitely should update this thread... turns out i was mistaken about being mistaken.
i called the dealer, he suggested that maybe the carbs had gotten gummed up due to the gas sitting in the tank for a couple months over the winter, and before i brought it in i might want to consider running a bottle of fuel system cleaner through it and letting it run its course. so i did it, and i just rode it today, and feels better than i remember it before.
so the bike is and always has been perfectly fine, it just wasn't properly winterized.
i figured something was amiss when i could find NOTHING on any message board, bullshit yahoo comment, or otherwise sourced complaints about the reliability of any hyosung motorcycles from a legitimate source (say, someone who owned one maybe?). i knew i hadn't beat up on it hard enough to justify a bent valve, so i kept putting off taking it to the dealer until i finally called, and i really wish i had earlier, because i would have been able to ride it on the few nice days we had the past couple weeks.
so yeah, no bent valve, and i retract my previous statements about the build quality of the motor.
skroozloose, if you do happen to have a confirmed source of said poor build/material quality, can you give me a link? like i said, i couldn't find anything, in fact i found a lot to the contrary, that these are actually really good bikes that are gaining a huge following in australia, new zealand, and the uk.
