I ordered a motor from bikemotorkit.com and the motor arrived in four days. It was missing the gas cap. I called the guy and he makes it sound like I must have lost it. I just got the darn thing, how could I lose it? He reluctanty said he would send one out that day. It's been over two weeks. I am pretty darn sure he just blew me off. Afterall, he already received my payment. I will never ever buy anything from Bikemotorkit.com again. His advertisement says you also get detailed instructions. I didn't get any instructions. Get on your motorbike and ride as far away as you can from this place and leave them in the dust.
