Chain problem
mike the bike:
If you've got a link splitting tool, why bother with the soft link? Couldn't you just join the two ends together, deleting the split link.

I put on the rear sprocket and new chain but kept the old front sprocket as I am not sure how to replace it.
After having completed the job I have realised that the chain is very loose, i pushed the wheel to the very end but still way too lose.
Shall I cut some links off the chain or..
thanks

Same here. Just had a chain and sprocket kit off eBay from M&P for the CB750F2

Fitted it last weekend and like yours the adjustment is past half way. So tomorrows job is to remove the required links and put in a soft rivet link. Don't like split links on 630 chain, although I don't know of any problems so I'm probably being way over cautious. Was always told from my teenage years that 65hp was the limit for split links (this may have been true of 70/80s chains). Its probably bullshit but what price your crankcases if it breaks.
Not even going to bother with the ringing M&P as they will only say "we've sold thousands and this is the first report of a problem". That will just piss me off. So out with the link remover again.

Surprised at M&P's response Roy, I only ever had good service from them, but it just goes to show that all suppliers can be a problem once they've got the cash!, regarding split links yes you are being over cautious, but why not when its so easy to use the soft link, if anybody does want to use a split link though they shouldn't worry, I've seen them used on 500bhp drag bikes without an issue, there should be no side loading on a chain so the split link doesn't take any stress, I use a split link on my XJR1300.....famous last words? :)

That's the plan Mike. The rivet over link that I bought is called a Soft Link, as the ends of the link that get riveted over are soft so they can be worked easily. Probably me not making myself clear again. ::)
royhall:
Just want to be clear on this Mark.
I didn't ring M&P as El-Burro had tried and got that response.
I to have never had a problem with M&P and I don't really consider this a problem as I can just shorten it so not worth the trouble ringing. If it had been too short I would have been on the phone in a second.
Just mentioned it as it was the same as El-Burro's problem.
I have a split link fitted at the moment, but the spring keeper on it is not tight and moves around slightly. That makes me nervous about it.
mike the bike:
I know what a soft link is, I use them when replacing cam chains. I was wondering - why bother. if you're going to remove links anyway, why not just join the chain together?
