heys guys my uncle has a 2003 softtail standard and he told me when the bike is cold he can hear a loud knock like a piston slap..it only does it when its cold...now he told me while its cold he can roll the bike to where the front tire hits a wall and he can let out on the clutch and put a load on the bike the noise stops..he also says that the noise will stop after the bike warms up after he rides it up the street and back....what could be causing this....thanks for any help

 

How many miles are on the bike, and what kind of work has been done to the engine if any?

Drew

 

it has 1124 miles,,,88tc bone stock

 

Has it had the 1000 mile service? I'd say clutch adjustment although I could be wrong. If not , when was the last fluid change?

Drew

 

im not sure ..he just bought the bike and the guy did say he changed the oil but im not sure about the complete 1000mile service or the clutch adj... i will ask him and post

 

Have him pull it up to your monitor and I'll give it a listen.

 

well im in ky and my uncle who bought the bike is in deland fl. so i cant do that...lol...

 

are there any write ups on clutch adj. on a 03 that i can pass along to him so he can adj. the clutch and see if that dont help him...

 

i had a knock sound that went away when warm. it turned out to be the rear mounting bolt was loose

 

I'd start with a oil change and clutch adjustment as suggested above. If that doesn't fix it, visit a dealer and ask them to listen to it. Opinions are free, at least at the dealers by me.
