Re: So my bergs cracked 200hrs

That is true, put the word motorbike on something and triple the price! It is great to read on this site all the stories of people getting such long lives out of their bikes, my 2010 570 had a full rebuild at 23 hrs! That was due to a third party that i wont go into here but its back together now and i hope i get the same life out of it that you guys have!

Thanks for all the info guys. My 07 Fe650 is at 160 hours. So looks like valve springs and cam chain etc should be replaced..

the stock valve springs get shorter over time, eventually they don't have enough prelaod to keep their resonance under control and break, the rhs exhaust valve is the one that gets shorter by the most. you can keep upping the preload to get around it and there are people with 500+ hours on their oem springs having never done a thing to them.

there is quite a big choice of dual valve springs, KTM oem part is the cheapest at about $65, they use it in RFS builds regulary ... AFAIK there has never been an issue with them.

my favourites are the Kibblewhites, they offer the best power gain and are easy to install at the right length

detailed specs here All About Valve Springs! (with nice pics)

forgot to mention my valve springs, cam chain and cam followers were still fine at 220hrs , then i rebuilt it into a 700

FWIW I give my bike a fair flogging.
