Cam chain replacement

Hi All,

Is it really so that you have to take the entire engine apart, in order to change the cam chain?

As far as I can see, there are no removable link in the chain. Neither in the one currently in use, or the replacement that I have bought.

I am doing a complete engine rebuild now, so this time it is not a big issue, but I am guessing that you would change the cam chain more often, that you would dismantle everything.

What am I missing?:confused::confused:

Best regards,

Michael
 
As Chuck said, you must split the cases. I recently achieved this rank thanks to the good folks on this forum. Read twice, wrench once. In my case, I read 18 times before I was confident enough to touch the motor but all is well that ends well.
 
Cam chains are sold "endless" or open.

you can "break" the old chain, connect a new chain,
pull the new chain through the engine, and connect the open ends.
No need to take the whole engine apart for a cam chain replacement.
 
Please post up an open one. Ive never seen anything except the endless chains without a break point. I know that some old Yamahaulers had master linked cam chains
 
But where do you get a master link for a GS engine??? Thats how the Yammys do it and I have the peening tool for the pins.
 
Just viewed the link....so show us one for an actual GS 750. 450, 850, 1000...anything. The 1300 Bking may use them but I assure you i have never seen an open chain for the bike he is talking about.
 
Cam chains can be bought in raw lengths (non joined). These chains require the pin be peened over to join the chain together; there is no master link (typically). Doing so is a bit controversial. Some people refuse to do such joining for fear of it coming apart and other people report success. Sort of like the subject of going tubeless on a GS wheel. Opinions vary.
 
My question is "what is forcing the replacement of the cam chain?"

Unless something catastrophic happens, they are usually good for well over 100,000 miles.
 
Yes Ed..maybe my choice of "master" link wasnt politically correct but I think we know what i meant

not the case with a GS i'm afraid ... though they may not break, i have never seen a cam chain on a GS that was still within the wear limit after 70K ... (that's kilometers so not even 50,000 miles)

What is forcing the replacement is a worn chain makes it impossible to adjust the engine properly. Valves open and close off-timing and the engine will not run really nice anymore.

Ok. So there is the chain breaker option, if you dont want to take everything apart.

As I am allready taking everything apart, it s not a problem for me to change the cam chain the "right" way. I had just hoped that there where a 3rd option, that I hadnt thought of.

Thank you for all your input and help. Much apprieciated.

Best Regards

Michael

If that was true than how come we have members around here with over 100k MILES on their GS's (with original cam chain) and the bikes still run nicely?
 
i guess you're basing that on the picture alone ?

it's in the ad ...

Please Note The Picture is a Generic One.
Please Check If the Correct Amount of Links on Your Old Chain Matches Our Listing.
The Listed Product is a Direct Replacement for your Original Part.

the point of this conversation imo still being it is not necessary to completely take apart the engine to replace the cam chain.
Ask any professional motorcycle repair guy - it makes absolutely no sense to take apart the whole engine for a simple cam chain replacement.
Cost-wise, that is.

Here's another manufacturer that delivers open cam chains.

Yeah i saw the picture and assumed incorrectly it was what the seller was representing as a cam chain.
