Hard to keep the front wheel on the ground with the 140. It will be a wheelie machine.tmas did you mean hard to keep the front wheel on the ground with a 140 or hard to get the front wheel off the ground?
To be honest i didnt even think any of the 140's came with auto clutches because of that reason. If they do then im sure its sturdy enough to hold. By big power i meant any of the Big bore motors like a 140 or 125.What do you consider big power? I’d probably be keeping the 140 engine stock & I’m about 150 pounds so as long as the clutch would’nt slip with that kind of weight, I’d be good.
