Cam chains

11 posts in this topic

Cam chain question,, 08 yz450,, is the stock chain good enough, or would an after market be better. I see there is a big difference in cost, but does that equil quality?

I just went through the same thing this past Fall, I had 60 hours on my original cam chain and wanted to replace it. I went with another OEM chain, ordered 2 at the same time and now I've got a new spare in my tool box. I'll run the chain that's in my bike for 50 to 60 hours and replace i again.

My original cam chain had 6 or 7 links that were starting to bind (very noticeably by hand) when I pulled it out & only had 60 hours on it.

What oil are you using. I have an 09 with over 350 hours and has never been opened up for a cam chain or anything.

I can't help but to ask you also. What type of riding and at what level? 350 hr.s is mighty impressive! That makes me feel good about my bike all over again.:excuseme:

So,, I'm an old Suzuki guy, had several thumpers, DR's, QuadSport, and street bikes. We NEVER changed cam chains!! So are the cam chains in the early to mid 80's better than ones we get today? The 1985 Quad we wore it out, split the cases, rebuilt it,, wore it out again, rebuilt it, and rode it some more, and never replaced the cam chain. If I had a guess it had 5000 hours on it or more. So what's the deal?

Let's keep in mind that the OEM cam chain is $17.36, a Pro-X cam chain for the same bike is $64. I'm a firm believer in "you get what you pay for", and for less than $18 I'm not going to risk completely destroying my engine for such an easy/cheap fix. I'll run the OEM cam chains for 55 hours max., no more. If you have more faith in them than I do, :excuseme:

I should mention that I couldn't find anything on the internet as far as which cam chain (OEM vs aftermarket) wears better/longer, tensile stregnths etc.

The bike is ridden single track and motocross tracks by my son in law. He's a fast b rider.

We use Redline 10/40 motorcycle specific oil. Redline uses the best base stock known to date.
