Yesterday I finished a full motor job on my 2014 trv550. I put it all together and it runs well, sometimes. When cold, it takes a little bit to start, but that isn’t my main concern. When starting from cold it runs fine, but when put in gear and driven a bit, it makes an awful lot of odd clutch noise. It kinda knocks a little and also idles very slowly when doing so. I know it isn’t the motor, because it runs well otherwise. Any ideas? I put a new crank, main bearings, counter balancer bearings, piston and rings in. Is there any known issue that could cause a lot of clutch noise? It blew up 2 years ago and just rebuilt now. Please help!
