sharp sprockets and loose chain

[meruuu]

hi bros, i'm riding krr150 now(swingarm).

 

recently, theres this very loud TUCK sound when i'm riding. this usually happens in gear 1,2 sometimes 3. higher gears theres no such problem.

as far as i know, the chain is loose, and the sprockets are rather sharp. pay hasn't come in yet, so might be waiting till december to change the sprockets chain. so i'm wondering, is there any problem or danger if i dun change it asap ?

 

its only my guess that this sound is coming from the chain and sprocket, could it be the gear box or something ? or any other possibilities ? enlighten me bros.

 

thanks alot!

woah bro better change it asap.. worse case senario you riding chain break u stuck in the middle of nowhere... then waste money call for tow truck come and save you... but if u really on budjet i suggest u go bike shop tighten your chain or diy and ride slow.....

[meruuu]

lol thnx bro mokz. went to shop to tighten chain, mechanic tightened it to the very last bit. now its doing fine. but advised to change my sprocket. will change it soon.

 

Problem solved. thanks for the help!

no money, change a normal cheap chain 1st. can at least last you for few mths.

it a damn dangerous thing! I experienced chain broken at expressway before! damn sian manz..... luckily the chain never stuck or what, it just drop off to the road if not sure jialat. When its time to change, no matter do what also no use liao de, this type of safety thing!

rmb to lub ur chain...

its will make the tightening last longer n ur chain's life

[mokz]

hey no prob

meruuu..You still riding KR? Think I saw a familiar bike..Pramac blue and black FBA plated KR..Your friend's?

If the chain snaps, it whips around at very high speed. I've seen cracked engine cases with huge holes caused by the chain. Can you imagine what it will do to your legs?

 

That chainguard is not there for no reason. And it doesn't offer full protection too.

thnx guys for all the comments, since chain tighten, shld be able to last a month more before i change the sprocket. thnx guys!

yea my friend's , he was from tampines ite too. but i tink he just sold his bike recently, upgraded.

my kr chain sprocket also like that. tighten to last bit many times. until very cannot make it. today jus change chain and sprocket nia. same problem as u.

Always keep the drive chain lubricated and properly adjusted.

 

Cutting a link off to make a stretched chain still usable is a dumb thing to do... something only recommended by ignorant mechanics.

 

Under hard acceleration and downshifting.. chain link plates will stretch, thereby lengthening the gap between the chain rollers.

 

A new chain will sit squarely on the sprocket with the chain rollers in the middle of the sprocket groove between the teeth. Once stretched, the rollers tend to sit on the rear side of the front sprocket tooth and on the front side of rear sprocket tooth, due to accelerating loads. Cutting a link off serves only to make the situation WORSE. By doing that, you accelerate the wear on the sprockets.

 

After sometime of running with a stretched chain, the sprocket teeth will be grounded to a sharp point which is hooked at the tip. Thats when the chain is able to slip and jump sprocket and get jammed simply because it is not sitting in the sprocket properly under loads.

 

Consequences of an improperly adjusted chain jumping the sprockets?.... instant locking of the rear wheel, instant jamming of the engine resulting in bent internal gears, con rods.

 

Don't be penny wise and pound foolish. Save 10 cents lose one hundred dollars.

 

Replace the drive chain BEFORE ie 3/4 way reached its limit of adjustment as indicated on the bike's rear axle markings. Do this and chances are the sprockets can survive a few chain replacements.

When the chain is already loose (cannot tighten anymore) or your sprocket is already worn out, better change fast. I had an incident whereby the chain actually came off while I was riding along SLE, all because I kept procrastinating to change it. Luckily the chain did not get stuck in the gears or something like that. If it did, I doubt that I will still be typing in here cos I was travelling at about 110km/h when that happened...

thnx guys for all the comments, since chain tighten, shld be able to last a month more before i change the sprocket. thnx guys!

 

Its not a comment. Its a warning. If you can't afford to replace the chain then take a bus till you can.

hey guys will e bike still be moving if e chain has came off??or will it stop to a halt?

[kito]

anyway apologies if i dug out a pretty old thread..

[KAWASAKl]

still can move but lose power and stop grudually depending on ur speed.

still can move but lose power and stop grudually depending on ur speed.

 

so meaning to say that no matter how fast u're moving, the bike won't come to a straight halt?

[KAWASAKl]

unless ur chain get stuck inside the wheel.

ok:giddy: ..thanks bro..now that cleared my doubts..
