New Big end bearings 156 20ts
Hi, my 156 is in garage tomorrow for warranty work after a Technician from another garage heard a very slight rumble from engine at 3000rpm. Both said only shells need replacement due to the fact that the rumble is barley even audable and unlikely that crank has been damaged. I have some technical knowledge and am happy with the shells just being replaced, anyone got any input should I insist on crank replacement or re-furb or as they said its not knocking just a very very faint rumble when held on and off rev at 3000rpm.
P.S I couldnt even here it rumble but they insist it does? what u guys think?
