mouradjan · 07-12-2016, 12:47 PM

Hi friends .Last week while i was riding about 50 miles an hour Rx3 stoped working and motorcycle continued moving like bike is on neutral even it was on 6th Gear.
Dang.... i figured i had a big problem
Here is the chain photo .it has codes on .May be it will help u to find it when u need one.
Btw when chain is broken ,cylinder hit the valves.they are warped 😢

I wonder how the heck that happened? Were your valves set properly?

Mechanic asked the same question .He said may be there is a problem with the chain tensioner and may be there is less oil then it shoud be.

It's nice that they use a DID chain. That pretty much eliminates any possibility of a defective chain.

so this is 2 years parts warranty, right? i would assume it's eligible for replacement parts from your local Zong Dealer? I see you are from the Republic of Turkey.

What was the total mileage/kilometers on this bike?

It Looks like you have the situation under control

Hope everything goes smoothly for you.

Yes it has 2 years warranty. The dealer is replacing the parts.My bike is on 17k kilometres .

Sorry to hear about your problem.

Looks like a failure of a name brand part if that's a DID. I don't see that in the picture, but I'm not a DID authority ;-). Odd but it happens. I've never heard of a cam chain breaking before. I wonder if something else failed that CAUSED the cam chain to break. Seized camshaft bearing for example.

I don't think it's possible out of adjustment valves could ahve caused this.

Once again I'm impressed with Zong's warranty.

You have to scroll the pic over to the right to see the DID stamped link.

I've seen lots of broken cam chains on Hondas, Yamahas, Suzukis, etc., which is one reason I really like the CG engines.

I was curious because if the valves were too tight and one hit a piston dome (but it would have to be damn tight?), could maybe cause it? Odds are though it could be a tensioner problem or something else. Just weird how it snapped like that.

I know there's tons of RX3's around the world doing mega miles and these things do live in a very high rpm range. Who knows...........like you say though, the CSC warranty rocks.

Today i talked to Mechanic .He told me that if i lower the Gear on high rpm it may cause this break.
