I hate to say this but no. The engines are the fastest they have ever been and they are winging around 41k. They will stretch or break the rod due to the stress and load. So it is my opinion that for the 30 dollars you need to spend to replace the conrod 3 times in the motors life is much cheaper then the motor when you blast the rod out the side of the case. Which will happen if left unchanged. You can try breaking the engine in with the rod it comes with then, take that rod out. Save it for another break in cycle on another motor or piston/sleeve combo. Run the new rod you just put in for around 1and 1/2 gallons max then change it. You can save a little there. Maybe a bit of help. That is what we do when we break the team engines in.
