Dear all,

My cb 450 K5 need new pistons so I took the engine apart.
The engine was running smootly without unusually sounds, he has run 53000 kilometers.
Can someone tell me when I must replace the camchain? As far as I can see he is looking oke, but is there a way to see that it is better to replace or not? Maybe it is already replaced in the past, I do not know.
Thanks for your advise!

IMHO this is one of those "as long as I'm in here" things. You can also measure how much "stretch" you have by measuring between a given number of links with the chain stretched verses the same measurement with the chain compressed. Different sources will offer different standards but somewhere around 5% is usually considered max.

Since you are already in there might as well replace it and have some peace of mind.

Absolutely agree as well - since you're probably only going to do this once, I'd definitely recommend replacing it while you're there. I'd also recommend a DID replacement as it was OEM for Honda at the time, I bought this one for mine and I believe 76TWIN has as well

Oke guys,
I understand it, the price of the chain is also not as high I expected.
Thanks for the info and link to the proper chain type.
Regards,
Eric
