i would have said a normal relay doing it. But im thinking that even if your running 2000 rpm that would be 1000 switches a min or nearly 17 times a second. im hoping im right that the 2 strokes fire every revolution so your talking 34 times. i really think this might fry the relay before its even really got going. as youl only be wanting it open for what, quarter or a rev ?, at 34 times a min gives around 1.7 seconds so a quarter is just under 0.5 of a second

fiddly yeap i can see this becoming quite difficult
