I have a Gensis but can't tell how the motor is as I can't keep it from breaking long enought to get a good run out of it. but, CEN has been very helpfull and I get same day email responces and so far the yhave sent a LOT of free parts to replace and upgrade my truck for free. I knew there was going to be some issues getting this thing to run, but not as many as i have had. but as long as they are stick by it I am happy.
