bro is the shop any good?

if so, how much?

 

 

keep us posted will ya...

 

 

 

thanks

[calvin_haito]

i don't know whether is good or bad...

personally i think not bad la... what i heard their repo quite good, but i say honest cos they know they did not done a good job so they try to help not matter wat...

so i guess is the encounter that u decide good or bad

wash and tune at 80, i guess good job worth that price...

 

cheer and hope it help

[Legan]

Why do you say they didn't do a good job?

[calvin_haito]

firstly is tuning is off, but when i went back yesterday

found out that is my electric power weak so not enough spark for combustion cosing the unstable idling...

don't know how truth but bike now better, but alway scare that it fail mi again...

overall i would say to them...

[NoobVtec2]

hi guys, as above, is it normal? Did a search.. and someone said it might be the spark plug cap or sometin? Yeah the mech did took out my sparkplug and check.

 

Hope u guys advise! Thanks

 

oh yeah its not during warm up, i can still hear the click sound after riding for sometime

[sICkbOi-dOt-cOm]

if its on neutral still got sound ?? if clutch in got sound ? or no sound??

[NoobVtec2]

yapz on neutral got the sound.But anyway i think only netural then can hear mah, when move off the engine sound already cover it. Abt clutch in, i not sure need to test.

[William Tan]

Do you mean the ticking sound coming from the top of your engine? If it is, it's just your valves clearance requiring some checking.

Yesterday, i tried to access the carb on my specIII to clean it as the idle was not steady, so i suspected that the idle jets were dirty or clogged or something.

 

So, I removed the tank, then disconnected the hoses attached to the airbox, loosened the carb flanges, and managed to loosen the carb away from both airbox and intake flange sides.

 

But then i could not access the throttle cable bolt nut, and there was some electrical component attached to the RHS of the throttle.

 

So, I have some questions:

 

1) Can the airbox be removed from the bike first, while the carb is still attached? How to do it?

2) Does the carb (keihin VP?? - tried searching for info, nothing) actually come with a throttle position sensor? If not, what is that electrical connector on the RHS of the carb?

3) Is that electrical connector easy to remove?

4) What else must be disconnected before the carb is free? There's the throttle cables, the electrical thing, choke. what else is there?

5) How to open up each individual carb? I see four screws on top of each carb, holding down a round cap. Anything else to look out for?

6) Any precautions i should take to not screw up the carb?

 

I know many people will recommend that I just send it to a mech to have it done for me, but I am quite free this period of time, so i am looking for something challenging to do, so please help.

 

My experience has been with stripping apart one 2T single cylinder carb before, but this is really complicated in comparison. Any links anyone else has found that I can refer to?

 

Thanks!

alamak bro...not recommended DIY for yur carb...u dunt hav complete tools to do it bro...after cleaning u hav to tune up using a vacuum device i dun know wats its name..so the four carb eat the same air volume if not yur bike not smooth..btw the 2stroke carb are much more easier to tune up then the fourcarbs.. dangerous bro sumore yurs is vtec3 n its still new..mine was vtec1 use for 2 years not yet service y..still run smooth....

How do you know your carbs are really dirty and need washing? If after tuning, the bike feels smooth and power delivery improves, why go through the trouble to open and wash? More problems may crop up when the carbs are often opened and tinkered with.

 

Motordiam need to make maximum profit, of course they will advise everyone to wash and tune your carbs. But the fact is that you dont need to open your carbs unless there is no improvement after tuning. Think about it.

Agree...

 

I've heard from a couple of mechs and they mentioned to me that for S4, we don't really have to clean our carbs...

 

Maybe someone can contribute on what are the symtoms to look out for when we really have to go for cleaning of carbs?

when i bought my ver s pick up sucked and full tank only can go 250km

then the mec advised me to wash and tune and he needed to change two nuts cause the previous owner itchy hand. After servicing and tuning , my pick up and top speed very good and my full tank can last up to 450km including reserve and im not joking!!!

Hi Bros

Ai before I read this topic.....I already went to Sanfu for Crab washing and engine tuning.....cos my FC is at about 240KM before reaching reserve. They look very prof lay......after washing the crab then they use a machine to do the tuning.....with four indicator running up and down.....

 

Then the fat fat boss offer to knock a hole in my stock exhart.....and I allow them to do it....he claim that is will help to trap lesser carbon in the exhart.....

 

I am still trying out the FC.......jsut went to JB to pump at Caltex.... Riding a SPec 2 and total damage is $70

 

Are they doing the correct things???
