Hopefully you've already solved this, but since I was here today....

What shape is your battery in? I think RC's (like most injected bikes probably) need good voltage to run right. At idle there's not much energy coming out of the alternator, so the battery is discharging. Even if it seems to crank ok, if the battery is questionable I would replace it and see how it does. Unless of course you have access to a battery load tester to help you make that determination. Just checking static unloaded voltage is not really applicable to this issue. By the way, with a good battery an RC51 starter will crank the engine pretty fast!
