A cracked engine case or worse is nothing to mess with.
I installed a new chain last month. At the time I didn't have the funds to buy the chain rivet tool for $100+ so I decided to use the clip-type master link temporarily. At the time I didn't realize how temporary that would be... I lost 2 of them!!!
The chain installed was a D.I.D. 525VM (came with a rivet link)
I bought the D.I.D. clip-type link (3 of them all together)
So as I don't get lots of "you didn't install it right responses" here's a picture of which way the clip was installed
Before I installed it I made sure all the surfaces where clean and there was enough of the pin showing that the clip could get into the groove on it.
In less than a week I noticed that it was gone.
I immediately ordered a Mike XS tool and in the mean time ran out and got a second clip and this time I added a bit of superglue to the backside before I clipped it in place. This one lasted about 2 weeks and was missing too.
I found this second one missing yesterday while at work (about 50 miles from home) so to get home I ran out and got a third clip and then went to Home Depot for some 2-part epoxy. With epoxy on the backside, and gooped all over and around the clip made it home fine where I changed it last night with a rivet link (which is what I should have done in the first place)
Don't cheap out and go with a clip-type link! I was extremely lucky that the outside link plate was on firmly and I didn't lose the chain. I've heard horror stories of chains going through the back of the engine case or getting wrapped up in the rear wheel.
On a side note the Mike XS tool doesn't come with instructions, I managed to find some for the D.I.D. tool which is virtually the same. At the end of this thread are some not so good photos of the tool in action last night in the garage.
This is just here as information and not to bash clip-type link users. If you use clips religiously then more power to you. Go grab your own soapbox, this one is mine LOL
