Chain problem

[MarkCR750]

Is the front sprocket currently fitted the correct one?, has it the same number of teeth as the one that arrived in the new kit?

Not sure, I guess it's probably a stock 18; rear is 48.
Still it wouldn't make that much difference.
What's the k2 chain lenght?

Thanks

I'm going to count the links on the old one.
Do the 106L on the chain box means 106 links?

Thanks

Yup

[El__burro]

I guess the supplier has got mistaken the box says 106 but it could be 104 as there is another sticker.
Sent a message to the supplier hopefully he would sort it asap.

thanks

A bit of headache with the supplier.  He's saying that the 100 link chain is for the US market (picture in blue) and 104 for EU (picture in black).

What's the real story?
Thanks

Motor vehicles in the u.s. have emmissions per mile measured, and it is actually illegal to deviate from the manufacturers original spec, even when the manufacturer does modifications owners must stick to what was originally fitted. It is actually a federal offence to fit alternative size sprockets to a bike to improve performance as that would alter the emissions per mile, an offence under e.p.a. regulations. It seems ridiculous that they enforce such stupid rules. and then march uninvited to other countries and start firing depleted uranium shells and bombs at them. Land of the free? I don't think so!

so, is it 100 link EU, US or generic?
the old chain is 100, new one is 104 and way too long.
seller wont take it back as he thinks is in the right.
DSS sells a 100 link ones (as per link above).

As long as you have a split link just shorten it

[MCTID]

The Seller obviously won't admit that the mistake is his.........they never do.....but why not ask if you can return it for an exchange and you'll split the postage (or you'll pay it if you are really desperate).

Good luck.

It's so easy to shorten I wouldn't bother with a return.

If you don't have the right tool then just grind the head off a pin then tap it out with anything appropriately sized - even a nail will do.

Thanks, it would save me £5.50

If you put in a vice with an M6 nut behind the rivet, you can press the rivet out using the force of the vice just to start it off and then use a punch on it.

[El__burro]

After grinding off both ends i used the old chain link to push it through with a vice using a large bolt on the other end;
that worked fine.
next..
How easy is to replace the front sprocket?
thanks
