How to tighten the chain on a VFR 750 (single sided swingarm model)

- Once you own a motorcycle with a centre stand and a single sided swingarm, its hard to go back to a standard swingarm motorcycle with no centre stand.
Its so much easier to tighten the chain on a motorcycle with a single sided swingarm. Just throw the bike up on its centre stand, find the tight spot on the chain, loosen the swingarm bearing pinch bolt and adjust the chain tightness using a C spanner (Pin spanner). Just note that you do need a C spanner to complete this job and if you are buying a motorcycle with a single sided swingarm then check that the C spanner comes with the bike as they're not readily available like other tools. You may have to order one online or look for one from a local motorcycle shop who don't always have spare ones for sale. The other benefit to the single sided swingarm is that you dont have to worry about alinging the back wheel as you would on a motorcycle with a standard swingarm.
Unfortunately not many motorcycles have a single sided swingarm. Its usually the reserve of high end motorcycles. But a lot of them can be bought for very little money like a Honda VFR or a Honda Bros if you can find a good condition older bike, particularly the Honda VFR. Early Triumph Speed Triples also had a beautiful single sided swingarm design and you should be able to pick one up for small money.
I'm sitting here beating my pin wrench with a hammer not able to get the chain adjustment to move. I can stand on the wrench and it goes nowhere. I've already bent the wrench and bent it back. The pinch bolt is finger loose like yours and it's just not working.
Incredibly frustrated since my chain has enough slack it sits on the center stand when folded up and I can lift it into the bottom of the swing arm.
Hi there! Can I ask on the minute 8:00, what is like the size/measure of that tool? the Pin Spanner?
I think in that video I used a pin spanner from a kawasaki ninja 250sl but I won't give you the dimensions as its a waste of your time. Buy the OEM honda vfr750 pin spanner. Anything else will just wreck the gripping points. Fowlers uk website where you will find them.
@@TheMotorcycleMuse awesome 👍 thank you so much for sharing with us!! I just got a vfr750 but it will require a lot of work haha... Thank you folk!!
Jezz 😂
Agreed, a bit too tight. I have one of these.
Julian, by any chance do you know the size of the pin spanner?
I think your chain is too tight. You have to put the bike on the side stand so that the rear tyre is resting on the ground. Now when you are going to sit on the bike the chain eill be very tight. It can damage the engine.
With the VFR's the prescription is to measure the chain with bike on centre stand. With my Kawasaki I measure the chain slack with bike on side stand and weight on the wheel like you described. Always best to check the manual for each bike model.
@@TheMotorcycleMuse In the original Honda service manual stands that you have to put the bike on the side stand.
@@harrykramer7479 ok. Somebody has to post a picture of the manual.
Yes, my Haynes manual for the R36ii says put it on the centre stand. Thank you very much btw for these helpful maintenance videos for the R36. 👍
@@harrykramer7479 Both my rider's manual and my Honda shop manual demand the bike on the centre stand.
But I do agree that the chain slack is set too tight here.
What happens to a bearing seat in the engine housing can be seen in the following (german) video, on a VFR 750 FG engine with 170 000kms on it. The bearing itself shown in the video is fine, though.

At that point, he talks about the circular elevation disappearing at the front side of the seat. Another user explains that due to own experience in a similar mechanical engineering context the wear takes place where the bearing loses pressure on its seat, so here it's on the forward facing part.
This video demonstration could have been done in about 5 minutes, not 17 !
