engine help

[ismeth]

Hi guys, i need some help.

My bike engine seems to sound different than it normally does before,

it sounds rougher, louder, less smooth and the bike vibrates more, usually 90km/h vibrates abit,

now 70-80km/h it starts.

And the pick-up seems slower, like no power.

 

i just changed, spark plug, coolant, engine oil, oil filter.

the problem still persist.

it's been going on for like 2-3 weeks.

anyone might know the problem?

it's a fuel injection bike btw, fz150i.

 

Thanks in advance:cheeky:

check your fuel....maybe contaminated...

check your spark cap...spark plug gap..

 

spark intensity....etc..

check your air filter...is it contaminated..

 

sound like a combustion problem..

if all ok...send to shop for trouble shooting.

 

you need to mentioned the age of the bike and its milage....maybe you need to change clutch plate

i don't think its oil or plug problem.

 

how to check air filter?

well the bike milage 85k, hahaha, i got it when it was at 79k.

so, does that mean i need to change the plate? ahahha

if you do not know how to check a simple air filter..

best is to leave it to the experts before it get worse...

 

at the 85k km...the engine is about to need a overhaul....all system check...in my opinion.
