macjaffa Posted December 22, 2021 Share Posted December 22, 2021 Aaaah, I left the stupid wheel lock on (it's not stupid, I am)...and bent the bolt on my chain adjuster. I am looking for a replacement, although the part is apparently discontinued...but I have some second hand on eBay I could grab...after Christmas ....a few questions: 1) The part looks the same as in the earlier GS 500's...is it actually the same as the earlier GS? 2). My chain is too tight. On the sidestand it has about .5/.7 inches of play (if I push it up from the middle). While waiting for the part...I've had the bike three months...I assume it has always been a bit too tight, but I didn't realise. Still...now I know...is it okay to ride? Because... 3). Until I replace the part in the pic...I can't loosen the chain. I believe that to loosen the chain I need to turn the nut anti-clockwise.. I might get half a turn out of this bolt...do you think I should? Would the bolt snap? 4). I take it I have to completely remove the back wheel to replace this part? As always...thank you for any help. Quote Link to comment Share on other sites More sharing options...
macjaffa Posted December 22, 2021 Author Share Posted December 22, 2021 Just to add...I've seen people describe the chain measurement in two ways. One is taking it from where it sits naturally, pushing up and then measuring....that is the measurement. The other is to push it down, measure, then push it right up and measure...and THAT is the distance (the aimed for inch). I did the first...so....that would mean my chain tension is okay, would it not? In which case...I can leave the adjuster as is...at the moment.

linuxrob Posted December 22, 2021 Share Posted December 22, 2021 sure a 600 bandit one will be the same? Quote Link to comment Share on other sites More sharing options...
macjaffa Posted December 22, 2021 Author Share Posted December 22, 2021 Update...I have one on the way now....£50....was that or wait until New Year for secondhand. Darn it. But now...how to replace.....and can I ride the bike in the meantime? Quote Link to comment Share on other sites More sharing options...
billy sugger Posted December 22, 2021 Share Posted December 22, 2021 Gently heat the bolt and straighten with a tube over it 1 Quote Link to comment Share on other sites More sharing options...
Mississippi Bullfrog Posted December 22, 2021 Share Posted December 22, 2021 You measure the total distance the chain can be moved from the lower to the upper. So if I've read you right then your chain should have between 1 to 1.4 inches of movement. If that is within the spec then you're ok to ride it. Don't ride it with the chain too tight. That can cause more serious damage to your transmission. £50 is a bit eye watering for one of those. Invest in a reminder cable for your lock.

macjaffa Posted December 23, 2021 Author Share Posted December 23, 2021 Ohh, dear....well...looks like I can't ride for a bit, then...until I sit out on the pavement and sort it. Thanks for your help and advice....I'll get to it. Fun times! Quote Link to comment Share on other sites More sharing options...
billy sugger Posted December 23, 2021 Share Posted December 23, 2021 Don't push the chain down. Take a steel ruler and hold against the bottom run, roughly in the centre between the wheel and front sprocket take a reading from the chain as it sits, the push chain up until it stops and then take another reading. That is how much play there is in the chain. PS, always find the tightest spot on the chain before measuring if possible Quote Link to comment Share on other sites More sharing options...
macjaffa Posted December 23, 2021 Author Share Posted December 23, 2021 Sooo....thank you everyone.... An update...I was able to loosen the chain using the adjusters...even the bent one allowed enough turns so that I now have an inch chain slack, measured from near the centre stand, when it is up. I have an inch from a low to high measurement, which is correct...I rolled the bike back and forth and remeasured...it seemed pretty consistent. I figure that as long as the chain is adjusted well, I can ride it...and I can take my time getting a cheaper, second hand adjuster...have returned the £50 one! I tightened the axle to 50lbs...as I believe is in spec?? I then remeasured the chain and it made it tighter (why?) but I repeated it all, tightened the axle and it's a good slack now. The last part of this job is to ensure I had the wheel aligned after adjustment...(I did the same amount of turns on the nuts, but...yeah). I measured from the centre of the swingarm pivot cap to the centre of the axle nut, on each side. It measured the same, although measuring alongside the exhaust was awkward. I went for a little ride and (apart from judders that I think were my imagination) it seemed fine. However....the adjuster plate on the right side is loose. Should I be worried? Here's a vid of it (in a Google Drive link). https://drive.google.com/file/d/1bgNNR4CV5mq8qn9Zi2v1MAP73Btwrei3/view?usp=sharing In my mind it indicated that the right side of the wheel should move forward....to make it snug. But so far....thanks so much for all the info and advice...I did take advice on avoid riding while the chain was tight...and this has all saved me money too! Thanks!

So many vids on youTube push the chain down, take a measurement, then push it up (past the midpoint where it usually sits) up to the farthest point and then take a measurement...the gap being the slack. But this is incorrect? Haha...have I done all this to double the slack that was actually okay? Got to just laugh, if that's the case.

Just from the middle up or from low to high? And do you have any thoughts on the adjuster plate being loose, like in the link, by any chance? Thanks!

Mississippi Bullfrog Posted December 23, 2021 Share Posted December 23, 2021 I do mine lower to upper. My adjuster plate often works loose after I've tightened the axle nut. Once the axle is tight, the chain is at the correct tension and the wheel is aligned just tighten the nuts on the adjuster arm to secure the plate. It's not going to affect the wheel alignment or chain tension as that's held by the axle nut. Quote Link to comment Share on other sites More sharing options...

Everything has a bow on it...and all's well! FFFANKS EVERYONE! I'm using the bike to go and finish some Christmas shopping, then. 1 Quote Link to comment Share on other sites More sharing options...
Old-codger Posted December 23, 2021 Share Posted December 23, 2021 AS others have said if the axle nut done up tight it wont move but if it concerns you just nip up that nut probably 1/4 to a 1/2 a turn to take the slack out of the adjuster plate.

Mississippi Bullfrog Posted December 23, 2021 Share Posted December 23, 2021 I had one of those many moons ago. It was really nice to ride. The only reason I got rid was that on mine the paint fell off every time it rained. I was forever touching it up. Quote Link to comment Share on other sites More sharing options...

That's great...thanks. I will do...I have the axle tightened to spec torque so I can adjust the plate nut and make it all snug. Quote Link to comment Share on other sites More sharing options...

I have a GSX600F the adjuster looks like it is the same. I think you will find the chain is now tight because of the damage to the adjuster. A 2nd hGSX600/750 should do the job.
