The big bore piston replacement was a direct fit.its well made a no fuss installation
Piston fits great, easy install and it lasts. I put a lot of hours on it and performance was outstanding.
The complete kit arrived in good condition and I wasted no time in fitting it.
Everything looked to be in excellent condition, my only issue has been the clearance, or lack of, between the new piston and the original cylinder bore.
I honed the bore and made sure there was no damage to the piston or bore.
In operation, it is obvious that the engine feels very tight and does not idle at all, however, I intend to continue to carefully run the engine in and hope that it will free up enough to idle and function correctly.
Works perfect and can’t beat the price pretty close to oem quality
Recieved the parts in great shape. Excellent packaging. Thank you! The parts fit perfectly and function great. Assembled everything with assembly lube. Adjusted valves and carburetor, starts right up every time and runs great! Thank you!
