Thanks for your input. Looks like it comes down to components. I could not find info on the Zongshen 250. If there were different performance options within that class of motor. Went with the Apollo 36. Will probably do a carb and muffler upgrade after break in. Will be interesting to see how the frame holds up. I went with this company in Tx.
