You saw petrol flowing out of a pipe is this normal Err, petrol flowing out of a pipe, let alone your bike, is bad enough already... You sure it's petrol that you've smelt?

 

As for 2T, it's okay. For me, one full bottle lasts me for a month on average. It's okay for your bike to "sip" 2T, not "gulp" it down as a small amount of 2T gets injected into petrol during the engine running process.

 

Tak Ling: Does it sound more like rocks hitting against metal?

[LostBoy85]

hmm ya it's smell like petrol.. if i never lead the bike to the left with 1 wheel up it will drip petrol .. for the sound now that u mention abit similar.,, it's like got sand hit to my bike like that kind of sound those sharp sharp sound and for the 2t i scare is my 2T too low spoil my piston? i also duno haiz

LostBoy85,

 

the leaking petrol is from your carburetor. It normally happens when you tilt the bike beyond a certain angle. As long as the petrol does not leak when the bike is on its side-stand (parked position), it should be no problem...

 

SP is well known for its tak tak sound (knocking sound) during idling... normally this happens when your carburetion is too lean (from my observation)... but i'm not sure if this is the same problem as what you've mentioned...

i think u change ur gear too fast at a low speed so the valve half open so have tat sound.. did u feel not smooth while riding?

[LostBoy85]

abit.. but even i idling also got that sound lehz

[irtif]

i got this prob also leh..... like very noisy like tat.. even cant hear my pipe sound leh
