Ah Pek where is the exact address of your workshop and what is the workshop tel no? I stay Sengkang very convenient to come down to AMK. Need to install gear indicator. The type that plugs in directly to the diagnostic system connector and lets it read directly from the bikes ECU. U have? If not I will go Motoworld.

Hi Biting_Point, John

 

Bro, thanks for checking out my ride n checking tat they're doing a good job. Yeah, maintained it rather well n not always using it. I also have a Subaru Forester09 2.5Turbo, Off Peak Plate. So if i have errands 2 run, will use the Super4. If I have several errands 2 run or if i have a golf game in the morning then no choice lah. Tear $20 coupon.

My Super4 is hard 2 believe its aged well. Hehe COE paid. And 2 think tat ASP wanted 2 trade in for $2500. Hehe would have been a sucker if i had traded in 2 get a new bike. Lucky, i have advice from u guys in tis forum. Thanks again n helping me save some $$$. Now my Super4 can last another 6-8yrs easy i hope.

Dear All,

 

I been having this question lon time but haven't got chance to post it up. Is the rpm idling supposed to be consistant coz mine keeps moving up and down and not consistant. Does it needs tuning?

Mine moves up & down too. My meter reads between 900 to 1.2k RPM - my mech says it too low for a S4. But he oso said, if it ain't broken, don't fix it. So till now, my rpm stil fluctuating.

1. Breaathing tube (thinest one) from the tank

 

2. Over flow tube (fat one) directly from the tank

 

3. Fuel hose (fat one) from the fuel kork

 

4. Vaccum tube (smallest of them all) from the fuel kork.

 

5. Two pin electrical connector (tank right hand side) only Ver R do not have.

Guys, what do you think is wrong my Spec III.

 

#1. Shifting from 1st to 2nd gear and then to 3rd gear at 2,000 rpm is smooth.

It shifts so smooth and almost noiseless at 2,000 rpm; I have no problem at all.

 

But if I shift from 1st to 2nd and then to 3rd gear at 2,500 to 3,000 rpm and higher rpms I hear a very loud “thuck” sound.

The “thuck” sound is loudest when I am shifting from 1st to 2nd gear.

If I shift from 1st to 2nd gear at higher rpm say 4,500 rpm it won’t even engage to 2nd gear, it will just stay at neutral.

If I force to go to 2nd gear at this stage I will hear crackling sound as if I am not fully pressing the clutch.

But I am pressing the clutch lever at 100%, so I wait until my rpm goes down to 2,500 rpm then I shift to 2nd gear.

 

Shifting from 2nd to 3rd gear there is also a “thuck” sound at 3,000 rpm and higher rpms, but not as loud as compared to shifting from 1st to 2nd gear on the same high rpms.

 

Shifting from 3rd to 4th then to 5ht and then to 6th gear there is “NO PROBLEM” at all rpms even at 5,000 or 6,000 rpm it is very smooth shifting and almost no sound.

 

#2. On idle at neutral I can hear a sound somehow coming from inside the right side of engine where the clutch cable is.

When I press the clutch levers slowly from 50% to pressing it at 100% the noise slowly disappears.

But when I release the clutch levers the noise is there again.

It’s like a tiny a tiny crackling sound.

 

 

Any ideas on the problem of Spec III?

[LaVsy]

anyone encounter of the engine oil drain plug screw, where you screw into the engine, the thread got worn out?

 

my bike is only 3 years old. And the bikeshop say is due to over tightening.

All this while i have been replacing engine oil at the same shop.

 

need to change the below engine cover and it cost $160.

 

does it really get worn out? my bike is only 3 years old.

is like indirectly telling me, my engineer here over tighten your screw.

 

Or is it part of wear and tear maintenance? have never heard of pple saying about changing the below engine.
