Still waiting for my 27cc Sikk engine. Ordered from Jerad Hill at Hookupz racing over two weeks ago. No replies to my emails and since it was paid for with PayPal, I am getting a little concerned. I'm still hoping he'll come through, but am losing hope at this point.
If anyone else is considering one of these engines, or a zenoah big bore kit, I'd suggest looking for a different dealer.
