you can remove the master link and with a socket and punch remove a link and re-install the master.

you can also get chain breakers at any auto parts store for about 10 bucks and it will save you lots of time and effort

[monster 84r]

i dont think i have a socket punch, what could i use to improvise?

[monster 84r]

wait i do have sockets, like spark plug sockets and etc. and a nail punch, how would i get the link out? how would i exactly remove a link?

[monster 84r]

before you cut it make sure that you have enough adjustment to take up the slack before you cut out a link. if you cut out too much you aren't going ridding to you get a new chain.

do you have a cut off wheel for the dremel?

Its way too loose, and R's are famous for throwing chains, as they dont have a chain guide on them.

Grind the ends of the pins off flush where shown in the picture. Grind flush and right on into the side plate a little bit. Then lay it on a hard surface, preferably cement, and use a chisel or screwdriver to force the side plate off by wedging it in between with a sharp whack of a hammer. The R has plenty of adjustment and you wont come up short if its all the way tight right now.

thank you timsr. so much, im gonna go try this. in the picture i have it tightened all the way, so i think it will work. i owe you big time man!

[sblt500r]

i never tried that. seems easier than what i do. i grind off one of the pins then bang it out with a punch.

[monster 84r]

ok guys im still screwed. i took out the link, and adjusted the chain as far foreward as it will go. now it is so tight i cant move it. will it stretch out, or snap? someone please help me i dont know what to do! how can i stretch the chain?

[ATCnut]

You need a half link.

[monster 84r]

ive never heard of one of those, can i get one at a local shop? i need a quick fix man, im going riding tomorow and my chain is way too tight.

[monster 84r]

if i ride it the way it is tomorrow, will it snap? what if i ride it easy? help me out guys, haha im only 15, i aint exactly a mechanical genious.

[monster 84r]

where could i get a half link? what could i do for a quick fix?any help much appreciated.

[84honda 200X]

You can get a half link at a dealership i know they have them there. Also maybe a hardware shop maybe! But i wouldnt ride it like that it could throw out your rear bearings or snap.

[sblt500r]

thats why i said to make sure you could cut it out and have enough room to adjust it and take the slack out. its happened to me before thats why i said it.

i think its a number 50 half link. but there more for lawnmowers not really meant for a atv. good thing its not an o-ring chain. pretty sure they don't sell half links for them.

[monster 84r]

thanks for the help guys, unfortunately i had to pass up riding today to mess with the chain :cry so a half link would work? any other options? i put the link back in so its very loose again,...should i try to take my sprocket back and get a bigger one?

[sblt500r]

or get a smaller one

[monster 84r]

i would but i didnt like the small size of a 12, looked like it would break. could i get the half link from anywhere open on a sunday?

[Old 179]

If he had a 15 tooth sproket and went to a 13 tooth,a full link removal should work perfect. I would think there should be adjustment in the adjuster (84 versus 86 what I have) should take care of the half link.(odd tooth) 4" grinder is what I use on chain links also.

[sblt500r]

i meant get a smaller rear sprocket.

try a home depot or lowes for the link.

[monster 84r]

i thought so too, but its not the case. i dont know what to do now, either i use a worn sprocket that fits or a new one that make the chain too slack or too tight. no one around here carries half links.

[monster 84r]

would a half link make the chain weaker? do alot of people use half links, or is it just a cheap quick fix? thanks for all your help!

[sblt500r]

me i personally wouldn't put a half link on a 250 2 stroke 3 wheeler. its not made for it. there made for low horspower applications. but i know people on here use them though.
