sprockets

[motovert24]

the bike just got everything done to it so the bolts were tight the chain was new
wheel was straght and i CHECKED EVERYTHING OVER 3 TIMES
a bolt came loose last year on my old hub but that was because the thread in the hub was gone and there was no sproket damage
i checked the bike before that lap that happend nothing was wrong
track was very ruff and very muddy a big puddle very corner on the fast 50 track
this happend on the intermedite track i clicked into 3rd and was bouncing from oneside to the other side on the track then crack bike turned off and sprocket was not on the wheel anymore (still there just not conneted)

He sure showed you guys up

hey you were doubting him too lol

and yes you most certainly snapped your sprocket...

another piece for the broken wall

and as thump was saying about mis aligned wheels, when i was ligning mine up cos i had to cut wheel spacers to get it all lined up i bought myself about a $10 builders laser level just a little blue and black box that uses 2 AAA batteries and sighted the top of the rear sprocket teeth to the ones at the front so it was in a perfetc line..

the laser level will also be useful to just check over now and then for alignment

lol i think the answer to this one is an easy one....
Harry you said the track was rutted pretty badly, and you broke your chain guide...

at a guess, i'd say you belted your chain guide into a rut, and given the chain guides run so close to the sprocket, i'd hazard a guess that's what lunched the rear sprocket... One solid whack would have done the job to shatter the sprocket, especially if you were on the throttle...

DVDrip is right, that style of sprocket is inherently weak, you're better off trying to find a solid steel sprocket... pretty tricky to go bending one of them... Yes it's heavier, but yes, it will also last longer and you wont bend it in a hurry...

That was the question at the start but it just turned into let's bag mv again

 

[thump*140]

dont worry about it mate, not everyone is as smart as you and me.

 

[sean01]

yeah id be more concerned about the hub..
sprockets are easy come easy go, but hubs basically means new wheel if the hub is damaged.

im going to put money on the chain being to tight or like thump said, severely out of alignment..

lets just hope you had the correct chain on it too..

also a thing to remember, when adjusting your chain.. you should be sitting on the bike to get the correct amount of free play..
and im not sure how many are aware but when you are doing jumps your chain actually gets tighter the more the shock in compressed..
also an over tightened chain and jumps can mean gearbox failure..

Yeah I know about the chain becoming tighter it may have been to tight
the gearbox should be fine tho right

 

[sean01]

next ride will tell..

also going by the pics of the rear sprocket, they appear to be steel

mate i reckon the gearbox should be fine the chain and the sprocket obviously took the damage

the gearbox would have been protected by a "fuse" being your chain and sprocket

by the way thats why i dont use high quality chains or high tensile bolts to hold the sprocket on its easier to repair a chain or replace bolts in the bush than to replace a gearbox...........

 

[DvDRip]

or just set things up properly with the chain tension right... wheel aligned... with high tensile bolts and a quality chain and never have to worry about any of it?

 

[wogtaz ryder]

Whaaaaat? use the highest quality you can with the sprocket/chain ..... thats just stupid to purposely not..

 

[emmo1980]

yeah because china gearboxes are of such good quality they will never break hey..........id rather repair a chain in the bush anyday than push the bike back unrideable whith a stuffed gearbox

 

[wogtaz ryder]

How the hell are you gonna brake the gearbox by running a quality chain and sprocket bolts???.......... all tensioned properly..

running a **** chain will snap on you out of nowhere and go flying into your cases ...

That seriously is the stupidest thing ive ever heard

that depends on wether it shreds your hub or not.. which happened to me and attempted to use 2 bolts and 2 cable ties lasted about 500m and went again

 

[emmo1980]

i see your point

but look at mine obviously you have never pushed a broken bike 15ks through the bush with a locked up back wheel i just like to have a easily fixable weak link

 

[emmo1980]

i snapped my sprocket bolts off once took bike home drilled the broken bolts out put bolts right through hub with nuts on other side hard to tighten but easy to replace

 

[sean01]

hahahha, rubbish chain is your reason why you pushed it so far...

like dvdrip said, set it all up properly using quality stuff and it shouldnt ever come off..

advice like tht is best kept to your self..

you are a clown the chain didnt break the gearbox did and locked up i had no tools on me to take the chain off so i had to drag and lift the bike who said anything about it coming off?

anyway there is a difference between "shouldnt come off" and wont come off shouldnt means it still can but is not very likely im not trying to argue about this im just trying to get a point accross witch im entitled to do without people telling me how wrong i am when they seem to think i pushed a bike because something fell off!!!!!!!!!!!!!!!!!!!!

 

[wogtaz ryder]

So the chain had something to do with the gearbox breaking how?
