2 split links on primary chain

... which is sometimes needed to get an odd number of links. Given the pain of keeping the primary oil tight I would be tempted to replace the chain anyway - perhaps witha riveted link (although I'm always happy with spring links).

I wire mine. The wire does not touch the sprockets. If the chain is in good condition, why waste money and effort on it?

Jason will make an endless chain to the length you want, but I have never had a link break on me.

Check your sprocket sizes as its not normal to need a cranked link.  With the limited power of a Dommy  primary chain problems are usually caused by no oil  ,bad adjustment or the box moving back under the pull of final drive chain.

The only Dominator that needed a crank-link in its chain was the 99SS if the 21 tooth engine sprocket option was chosen. Usually this went in the rear chain. New bikes were generally sold with endless chains inside the engine. A spring link was often seen as the weak point in any chain and racing bikes tended to have their rear chains built up as endless.

The 'Chain Man' was selling DIY links for building endless chains........not too sure if he still does. But personally I would not use a chain (except in an emergency) with two spring links in it. 

You can do much better than a Reynold  which has not now got the reputation it did have. 

My primary has a cranked link and two links as a consequence, but it is a special. Should be ok if it’s all good quality.

Renolds chain got out of making motorcycle chain years ago, as stated earlier it is now just a brand name for some anonymous manufacturer. Regina/DID/Tsubaki/AFAM are all ok brands

Below as stated in most manuals.  There are variations depending on state of tune of engine and sprocket sizes chosen.
