Chain riveting…. do it yourself

Can you rivet the chain yourself? Yes. but use a suitable chain tool for hollow pin master link (e.g. DID, but also most other brands use this system)

Below the chain tool and a picture of a master link with x-rings and chain lubricant

chain punch

Chain tool in parts:

Chain Punch A : A
Chain Punch B : B
Anvil: C
Punching pin: D

My tip is not to use the chain tool to break the old chain, the pin breaks quite easily, the old chain can be divided with a grinder.

Fit the rivet link with the o-ring or x-ring rubbers in the prescribed manner (use the chain grease supplied) and finally fit the striker plate as shown above. I have used a different color locking plate for clarity in the photo.

Take the chain tool part B and place it behind the chain, the pins of the link are in the recesses of chain tool part B.

Insert the pin (part D) into chain punch part A with the thin pin facing inwards, so that the widest part still protrudes a little. Take the anvil (part B) and slide it over the chain punch part B. Make sure that the anvil falls exactly over the locking plate of the rivet link, see the picture below. Tighten slowly by hand so that everything is properly clamped.

You use two wrenches to tighten the punch until it can go no further. Check in the meantime that the locking plate goes straight over the pins). When the punch can’t go any further, the locking plate has been pushed far enough over the pins (can’t go too far!).

As a final step of the chain riveting process, the pins must be “punched”. To do this, remove the anvil (part C). Now position the upper part of the chain punch (part A) so that the pin with the notch is exactly on the locking pin. Tighten the chain punch again by hand and check that it is exactly straight.

Then use 2 wrenches to tighten the punch until it cannot be tightened any further. I recommend checking in between to see if the locking pin is evenly “bent”. Repeat this with thesecond pin. You then have the chain nicely riveted without it being too “tight”.

Then make sure you have a good maintenance so you can enjoy your new chain as long as possible. Use a good quality chain spray (spray every 250 to 500 km, note: do this after a ride on a warm chain). Of course you can also choose for convenience and mount a (fully automatic) chain lubrication system.

Oberon Performance Clutch Slave Cylinders

Clutch Slave Cylinders from Oberon Performance are a nice upgrade for those motorcycles that have a hydraulic clutch. Often this works great but there are also regular problems.

The original slave cylinder (comes with the engine block) doesn’t always work fine and dosage and there are also several that regularly break down, making the clutch not easy to operate. An additional problem is that the original cylinders are often quite expensive.

Solution for this are the Clutch Slave Cylinders from Oberon Performance.

These come with a lifetime warranty (in practice, they hardly ever break down) and with an optimal matching of the parts to the engine. This will in many cases make the clutch work finer and more controllable.

On our website you can find and order them of course. A small repair with lots of driving pleasure afterwards.

Barnett clutch conversion kits

Clutch spring conversion kits from Barnett clutches is the solution to clutch problems on a number of Yamaha motorcycles. Yamaha has equipped a number of its models with a clutch with a diaphragm spring. In practice, this system does not appear to work completely flawlessly. This makes the clutch more difficult to operate and sometimes shows very rapid wear of the clutch plates.

Barnett clutch spring conversion kits consist of a new milled pressure plate fitted with a number of traditional clutch springs. Below is an example of this.barnett clutch springs conversion kits xv1900
