Okay....anyway, I just brought up this old topic to get some information about clip links vs. rivet links.  I'm not sure what happened over the weekend, but it looks like the board may have lost a valuable member.  I did get your first comments Jack, but missed the other two.  Thanks for that first piece of wisdom and real world advice.  Sledge, I understand all that your saying, and will probably stay away from clip links, but a riveted chain sounds just as good as a factory endless link chain and is much cheaper.

Hmm... Closeout pricing...

Thanks for the link fettcols, I'll be ordering one today!

Bummer about GSJack....good first hand knowledge

After have been on this forum for the past two years...I know that GSJack is right on one thing...clip type chains are fine...maybe not for a 150hp bike...but remeber that are bike only makes about 40hp...so if you are not racing dont worry about it. If you do worry about it then go with a rivit type link.

As for sledge I really think that people on this board get way to involved into it and should just take a step back, not saying that you did anything wrong...but lets try to be friendly on the board.

As for real calculations about the safety lets look at a D.I.D 520V O-Ring chain
Average tensile strength of 6,830 lbs.
Max Torque Produced by the GS: 28 ft-lbs
Actual force applied to chain via sprocket(i am guessing but lets say 6 inch)=28ft-lbs*.6ft=16.8lbs
Now you said that a clip type is 20-30% weaker thefore an equivelent tensile strength is 4781lbs
now lets assume that you somehow produced ten times that amount of torque out of your gs(whellie  :icon_lol:)
16.8*10=168 lbs of force
n(saftey factor)=(tensile strenght)/(load)=(4781)/(84)=28.45
wow I think that the chain might be able to withstand our bikes...

Now i know you are going to make the fatigue arguement but crack propogation on chains is very slow, even with a defect in the link, beacause of the large radius pins that are used....and the clip that is used only experiences a small axial load, the pins do 99.9% of the work.

In conclusion....GsJack with his years of experience and a quick back of the napkin calculation shows yes....the mighty strong GS can withstand a link style chain.

In a way am sorry Jack chose to react the way he did, and I will say again that it wasnt my intention to upset him in any way. This is an open forum and people will make replies that are misunderstood. I do however feel the issue of splint links is an important one that I do feel strongly about for the simple reason its safety related. If the link fails at speed and you loose control or if the chain locks up the back wheel you will get hurt. Period. Motorcycling is a dangerous passtime at the best of times we all accept  this fact and take the risk but it makes a lot of sense to me to remove as many of those risks as is physicaly possible and I think it important to emphasise the point to the individuals who are not as aware of the dangers. I will not accept that a splint link in the chain is a justifiable risk, they can and do fail. Ok fitting an endless chain can be expensive and difficult and a pain in the a** but so is spending the rest of your life in a wheelchair.

As Jack said "your life, your choice"

Enough said.

BTW Jack hasnt gone, he made a comment in another post this morning about 15t sprockets.

And he also said "gsJack is the gonefather of GSes.

Kerry's gone, Jack's gone, RG's gone, Davipu's gone. Who's going to be next?

Richard died in a motorcycle accident that was at no fault of his own.  We lost a good friend and good member of this board.  Though Rich may be gone, his legacy will live on here.

Hang out there, we may flame, but we don't hate.

My attitude is in serious need of readjustment, and I'm ok with that.
