Have they fixed the starting problem on them now then

, i had a 510 a few years ago, fantastic bike when it was running but getting it started could take up to an hour, then it would stop for no reason and another hour kicking and kicking, by the time i got it going i was too feckin knackered to ride it

Saw many guys on dirt tracks booting and swearing at Bergs over the years.
I am assuming things have changed a lot in the last 8 years ?
