Cam chain woes

[bobino2]

Hi gang, more help required please!
Following the death of my bike I conducted an autopsy and found the cam chain to have snapped, not surprising really as it was really (really) worn on the outside edge. I got the chain out after removal of the cylinder head and along with the chain I removed a rather tired looking tensioner and another 'bit' which isn't a tensioner but I think it guides the chain as it runs vertically between the bottom and top sprockets. Closer examination of the valves revealed that I was lucky to escape without any damage in that department.
I intend to replace the cam chain and with it the guides and tensioner. Looking around on the 'intranet' it would seem that obtaining a new cam chain won't be too much of an issue although I've yet to find a site offering replacements for the ancillary bits, the guides and tensioner.
Can anyone throw any light in this direction? Also if you had your bike in as many bits is there any thing you would recommend before I (or attempt to) bung it all back together. PS its a 1980 GSX750ET. Keep well and thanks in anticipation.

Would have been quite common at the time (80's ) to change the chain, guide and tensioner as the bike got to a high milage. Possibly even part of the standard service schedule. Expensive as well, so often ignored until the bike went pop.

You'd have been able to walk into a dealer and pick up the parts. For a 27 year old bike, good luck!

https://www.robinsonsfoundry.co.uk/ for new bits.

Or you could try asking on https://www.suzukiownersclub.co.uk/

I think it probably worth giving everything the once over, check the pistons, small end bearings, valve seals, etc. Its just a matter of how much effort you want to put in it.

Hi

Surprised it hasn't bent any valves. Got away lucky there. Also surprised the cam chain has gone, not being a Honda and all that.

Suspect it would be worth trying on Old School Suzuki for decent sources of spare parts.

All the best

Not 100% sure because I can only find the GS750E but the part number for the tensioner is 12830-09300, works out to £70 new

Bonus is that its the same part number for the GS550 so your not going to have problems getting one from a breakers or Ebay. In fact without even trying

item 190081761817- brand new £29 +£6
item 270089669378- 99p + £5 used



Assuming the part number is right
