Suzuki GS550E — I'm attached to this little bike.
It's nowhere near restored or concourse, and likely never will be, but looks pretty good considering the condition it came to me in. I'm always doing little jobs on it, and enjoy the odd ride out even if the seat is as hard as wood.
The chain and sprockets were well worn, in fact the chain I was using came off my Gixer1000 years ago. So when I saw a NOS standard rear sprocket for next to nothing on eBay, I snapped it up (obviously a fifty tooth sprocket for a GS550 is not a common item now). The gearing on the 550 was way over the top before, and was fitted with a 43T on the back. I'd always thought it had the wrong chain guard on it because of the huge gap underneath, but that wasn't the case. Standard size was seven teeth bigger.
So now I needed a front sprocket and an O-ring chain to go with it. A quick look on eBay and there was a shop selling both, with different sized fronts if need be. I decided to go for a 16T to give the GS a sightly more relaxed time (15T is standard). The prices were superb, and with a little more investigation I found out they were actually on the Gold Coast.
So I popped in...
Drive Chain Maintenance.
A bit of a back to basics story here. I thought I had this covered sometime back, but I actually don't, my bad. A couple of weeks ago, a geezer asked if I thought the chain on his Ninja 300 was worn out. Wish I'd taken some pics of it now to give you a better idea.
The chain was hanging down in a large arc because it needed adjusting so badly. On closer inspection, it was also really greasy/dirty where chain lube had been sprayed on constantly during its life, but had never been cleaned. It was also heavy and slow to move because of the grease.
Now you can give all the advice you want in person, but words are meaningless unless you're doing the job with them, there and then. And if the person isn't confident in adjusting it correctly, it's a tough call. Everything is easy when you know how.
Regarding the wear factor? It was half-and-half. Yes, you could pull the chain links away from the rear sprocket slightly (a good test for a worn chain), but then I've seen far worse. If it was mine, I'd give it a damn good clean up first, spray it with chain lube again, adjust it and take it for a ride. And then monitor it for a while.
So, a good time for a tutorial. Take from it what you will, ignore it completely, or find out how I get years from chains and sprockets.
Here's a Can-Am 175 that is just beyond a simple clean and adjust. I'll admit defeat with this one.
