probly ur bearings and conrod worn out already. best if u get it changed quick. maybe ur clutch plates/springs worn out already.

 

overhaul costs depends on what you change.

 

find a trusted mech, open up the engine and check out whats the problem.

[epk]

one of the common problems of sp is the bearings. if you don't really take care of your bike, it'll tend to break easily. anyway top speed want so fast for what, this is only singapore after all.

[ZERO_shift]

Bro,I think you need to change ya conrod and bearings.It happened to me coz of the bearings.My mech says its like 8 yrs my bike still using stock sp bearings.Kana sai sum last owners never changed.That oso means that sum bikeshops never did do a proper overhaul.Its better that you are present there to see it yourself.

[dixon1990]

hmm r they expensive to change it?my mech jus changed my piston rings..and said that my vibrations had nth to do with my conrod..he even opened it up to show me dat nth is wrong..how does a conrod shows dats its worn out? wad abt bearings?

[dixon1990]

oh yea..how to see if the bearings is also worn out?btw..when i jus bought my sp not long and my sp had no air box..is tat a gd thing or bad?

[Toyota23]

at least 500 and Above...

[ost28]

[dixon1990]

at least 500 and Above...

 

wah..dats ex..he changed my piston and rings..and my bike pipe sounds even louder..zzz its faster in pick up sense..but for the pipe..i asked him is my pipe tong..he said yes..stock pipe..but only carbon inside taken out..and its v loud..zzz no idea how to siam LTA or TP..zzzz

[kwanheng]

wa no air box racer bike sia..... your engine sure got problem ur ex user is a racer so what do you think he will do to ur bike? check ur pipe muffer got mod a not cause mod muffer cannot use stock endcan with out mod thurs bike no power. when you change piston ring got check the block and piston got leakage anot? sure smth doing with block maybe port be4 one thats y so much problem.

[dixon1990]

hmmm..only mod i noticed is my pipe..stock pipe but theres a "750$ NUT" i asked abt it ..they said is clear carbon..is that illegal?

which part you talking about?

[BELRAY]

me too having the same problem! =.=

my bike can go only 140km/h

and my bike vibration when pillion ppl, can feel the whole bike vibrate like nuts!

there's alot of reason right? hmmm, does clutch plate and the spring will cause this problem like speed cant go above 140? and the bike vibrate alot.

because i think mine wore out already. hmmm...

[ost28]

clutch plate wear doesnt cause this vibration problem

 

the common problem with a poorly maintained sp is worn out crankshaft bearings which cause this virbration inside..

 

BUT .. there are other factors also..

like worn front or rear wheel bearing...

and clutch housing's getting looser over time

 

clutch plate wear is when u throttle alot.. then at a certain speed ur rpm shoots damn high .. but theres no pull on ur bike.. therefore no speed

machiam clutch in and blow like tat..

hmmm, but i only ride for 2months plus.

when i got my bike back, totallt no vibration at all.

pillion ppl they wont complain at all.

after now, i keep getting the vibration and its quite strong when i pillion ppl.

when im riding alone, it wont be so strong.

and i dont wack much leh. sian.

how do we check that the front bearing or rear bearing is loose?

what about clutch housing? what if its loose?

how much does it cost to replace worn item?

 

 

thanks a million bro for answering my enquiries!

[BELRAY]

bro ur valve got open a not? 140 is which gear?

hey bro, if you need some help with your sp, i recommend you try planet motor in ubi and let ah chong help you check. he's good. i got my sp from albert, full of problem, worse is petrol leaking and max speed only eighty plus... i went there, ask him help me check and fix then everything good liao.

anyway, an advice to you, dun bother too much about the top speed la.. singapore no place for you to go up to 140 without a high chance of accident. advice you to pay more attention on the fc. speed too high petrol also burn very fast. somemore petrol price now rising. all the best to you.
