Drive Chain Repairs and Replacement

    Motorcycle owners should make it a point to have the parts and tools required for repairs available both at their homes or shops and on the road. This means keeping the following parts and tools handy:

    Connecting links, roller links, offset links, spare spring clips, a punch, hammer, metal block and pliers.

Important: to maintain proper chain life, never use more than one connecting link on the chain drive
Other important facts:
• Avoid the use of offset links. They do not provide the same fatigue life as regular links
• Many motorcycles are now provided with special original equipment chains. When replacing this chain, be sure to replace it with the same special chain or a superior chain, such as daido super*speed. Check your motorcycle manual or your dealer
• Always be sure to repair daido special chain with the correct daido joints. Check your motorcycle manual or your dealer

Emergency repair: when a clip breaks and you have no clip immediately available, you can make a temporary repair by fastening a wire around the groves of the pin as in the diagram. Replace the wire with a clip as soon as possible. While the wire is in place, slow speeds and extreme caution are mandatory. Operating your motorcycle in such an emergency condition is dangerous at best and should be avoided if at all possible
    
Replacing the drive chain: there is a natural stretching of chain drives due to wear. The amount of stretch should not exceed 2 _ to 3 percent of its original length. Over this. The chain should be replaced (a proper daido replacement will give you the proper quality). Sprockets should also be checked periodically and replaced if worn.

Press fit connecting links: in case of breakage the best repair link is a press fit type. Join the chain with the connecting link. Brace the back of the connecting link with a metal or other hard material block, and tap the press fit plate over both pins simultaneously .use a punch to drive the press-fit plate to the edge of the chain and peen over the pin heads.
