knocking noise as in when u clutch in at neutral? then i think the cam tension or something like tat is loose...but then its normal.. no need to worry.

 

as for irregular idling.. wat u mean by tat? care to elaborate more as to when ur idlings are irregular? just start? riding? etc etc?

Cam tensioner usually sounds like tick tick sound. Like what bsk_R103 puts in, after the bike fully warms up, it's ok but the idling needle at the tachno seems to be jumping . Whenever in low gear, the bike seems to be no power.o_O

not much difference between 95/98.. just follow the machine recommendations of min 95 will do. i tried using 100 Ron mogas b4 and 92 Ron mogas on the track.. not much of a difference in terms of performance.. but generally 92 ron will burn faster compare to 98 (heavier density and boiling pt)

hmm..the tick tick sound normal la.. no point spending a bomb to rectify the prob unless u gonna open up or gonna open up ur engine?

btw i find that the bike has bad power in low gear.. maybe u wan try opening more throttle? its after all supposed to be whacked. hahahahha

once in a while a foul plug is ok, should not give the bike any problems

however if a foul plug constantly appears in the same cylinder then there will be some problems liao.. but urs new bike should be ok la.

change le then test again lo.

Thanks,vincent.Tested, so far no ok. But during cold start, still got the idling prb. Perhaps need to synchronize the throttle body.:cry:

  • 4 weeks later...

Anyone here has got the Engine stalling problem ? It often happens when you are slowing down and coming to a complete stop.... the idleing gets too un-stable and weak..... Its dies... :faint:

 

Anyway, HL just did some adjustments to my bike recently and I can feel the great difference. It no longer idle like its gasping for air anymore. Hope the problem is fully rectified. Keeping my fingers crossed and monitoring still.

 

And there the mech said it was due to wrong riding techniques when I first surfaced the problem to them.... Like a year ago ? .....

 

just for sharing.

 

Regards... :cool:

Speeding is the No.1 ROAD KILLER...... U may kill the road......
