Suzuki DT 40

[khj]

I have just bought a Suzuki DT 40. Serial number 823325.<br /> <br />It starts and runs fine, but it has a slight knocking noise that gets less when revved up and increases when idle speed.<br /> <br />I can locate it to the crank/bearing area<br />I suspect it is due to being run for a short period without oil.<br /> <br />I expect to chance the main bearings, but could it be something else can anybody help me?<br /> <br />Regards.<br /> <br />Kim

Re: Suzuki DT 40

you can do a compression test but the bottom line will still be the same ( rebuild or replace powerhead )

IMHO it sounds like a rod bearing.<br />-Don B

Hello Don B.<br />You were right<br /><br />I have located the problem to connecting rob bearing on the crank.<br /><br /><br />Do you know if they can be changed without changing the other bearings?<br />Kim
