Did any of them pics help atall mate ?

umm U said the chain is about 3mm to short right? put it on and then heat it up a little bit to see if it will expand a little then put the pin back in the chain then let it cool. its the only thing i can think of.

a chain thats too tight will cause unneeded wear on both sprockets and chain...

I can't tell from the pics but does the axle assembly possibly move forward or back on the radius arm? the bolt that comes through right in front of the sprocket in this pic http://www.diygokarts.com/vb/attachment.php?attachmentid=4427&d=1248894706 looks like it could be some sort of adjuster. But I don't Know, good luck though.

 

[damobear]

No it doesnt no form of adjusters what so ever, it really is getting me down lol,
everyone keeps saying there must be but there just isnt if i take a link out its 3mm to short and if i add a link its way to slack, and cant get an inbetween...? arrrrrrrrrrrrrrrrr shall i blow it up and claim on insurance lol, really stressing me out havent been on it yet and summer over almost

 

[damobear]

No toofarnorth, thats what i thought at first, was hoping it slid back n forth a lil then wud have been easy but it doest
have none of you heard of this thing i own either ?
sonik ?
crazy King 2, ?
yh250a (eec)
there the names i belive it goes under, i cant find anything online bout it really either, have the manufacture but mailed them over 1000000 times and no response

 

[damobear]

here is the bloody pain in the arse

 

[freakboy]

try gettin a iddler sproket and makin a small bracket that tensions the chain when u add another link.

 

[damobear]

A what ? would they know what i was on about if i asked for one of them in the bike shop ?
And is that
for the front or back sproket ?

 

[damobear]

if an iddler sproket is sumin that fits on a normal bike, i.e mountain bike or simelar that wont work mate, this chain is mega thick, the motor bike shop i got this chain from said it was very large, bigger than most 600cc bikes etc,

 

[toofarnorth]

The idler would have to mount to the radius arm, you would want it pushing up on the bottom of the chain. A farm supply store might have one or a cycle shop. If it was mine though I'd be modifying the engine mount or the axle to make something adjustable and not deal with the idler.

 

[freakboy]

its just a sproket with a bearing that moves freely just like a wheel with a bearing and u put it on a bracket to tension it all it is, is a free movin sprocket it fits ur chain and u just put it where it will push down on the chain to tighten it up.

 

[Kaptain Krunch]

You can even use a plastic idler pulley that is wide enough for a tensioner. That would be what i would do, i dont know how they can sell a kart with no chain adjustment...but ohh well. Sounds like its time for you to make a tensioner.

 

[toofarnorth]

If there's no idler sprocket on the right side and it works then it stands to reason that there isn't supposed to be one on the left side. Just for kicks I'd take apart that axle assembly starting with those bolts facing the rear that look like they hold that cap on, if that axle housing is off center it may act as a cam and move forward and back as you twist it giving you adjustment.

you might want to jack it up first. lol

 

[damobear]

somebody said to me that it didnt look cemetrical, but it has independent sespension all round if that makes sense, so u guys think the best way 4ward is to fit a tensioner yea ?
and how wud i go about starting to do sumin like that ?

 

[freakboy]

just make a metal bracket with a small plastic pully on there wider then the chain that presses down on the chain its simple but effective mabey just have a arm and a spring to keep it down
