fire

I crashed my RC at Thunder Hill in California last weekend making a rookie mistake. M body position wasn't great and I was leaning the bike over too much. When my foot peg scraped the ground, I got scared and overreacted by standing the bike up. I both wheels slid and before I knew it I was on...

Does any other RC 390 owner have any issues with the idle on their bike? My idle speed seems to fluctuate sounds like it has a miss fire every 5 to ten seconds or do they all do it? Any feedback will be most appreciated.
