Starter chain - how many links?

Tried again and chain definitely does not fit - see photo

Does anyone know what the pitch of the starter chain should be? Measuring the cog I would say 8mm, supplied chain is DID219H which on checking lists as 7.77mm though my measurement was a bit less but definitely less than 8mm.

Interesting. All of the printed references that I have access to, state that the 28101-253-000 starter chain is a 219 chain (7.77mm pitch), 58 links long. So, I resorted to actually checking my bikes and spare parts (new and used). Sure enough, they're all 60 links. Don't know if there was a vintage typo that was perpetuated over the decades, or? Anyone with some insight on this would be appreciated. Regards, Chase

Chase, thanks for checking your bikes. To further add to the confusion David Silva had an original chain listed on stock in their USA warehouse and were good enough to get them to check it and it does have 58 links (though do not know pitch). Also all their literature also says 58 links.

Hi you may try http://www.sprocketsunlimited.com/ for all your chains give them a ring they are very helpful they even sell a primary chain I have one on my CB77 and no problems after some 1,000 miles or so.

What is wrong with the starter chain in your picture it looks ok to me ?

If it is to slack you could pack out the starter motor with some flat thin washers but this should not be necessary.

I put a split link in my starter chain so as it made easy to fit remember the chain is not rotating when the engine is running.

Edit I took a look again at your picture and see what you mean the chain is not on the front sprocket on the top pic, I would buy a new chain from the above that is where I purchased mine.

Hi SBMH

Yes getting one from sprockets unlimited might be an option but I do not want to buy another that does not fit so was hoping someone can confirm number of links and pitch. Honda documentation seems to say 58 links, 219 chain ....... but it does not fit.

I am wondering if the original was perhaps 58 links with a slightly longer pitch of 8mm but can be replaced with 60 links of 219 (7.77mm) but I have no evidence.

The new in the box chain that I have is marked 219. As well as your new 58 link 219 chain wraps around the crank sprocket, you'll be good to go with a 219. Regards, Chase

I had a 219 chain from my nephew's carting days and shortened it to fit a cb72 starter, it worked fine, all you need is a small link splitter. Just counted the number of links on 4 used chains (I throw little away), they are all 60 links.
