[Discussion] Carburetor
Hello! does anyone done a major servicing on carburator ?
I did mine, like change the insulators, the fuel pins as well as the semi-balloon thingy (which i duno what its called)
after the changes, my bike sound more bombastic (Firm) as well as the fuel consumption decrease.. : ) but all comes with a price.
Just wondering if any1 did the same as well & how long will this condition lasts.

I did mine too quite recently. Changed every thing inside. Like the o-rings, jet thingy, etc etc. Now my bike can fly!!! Haha.
Damage: $520.80

true.. can feel that the bike can run more smoothly & of course more powerful..
hahaha : )

all about good tuning(carb balancing and correct air/fuel mixture adjustment), but why so expensive($450,$520.80)...?is it dynojet jetkit ?
Class 2 = 2007 CB400 Ver.S
Class 2 = 2008 TA 150
Class 2 = 2009 CB400 Vtec II
Nopez... Carb parts are generally expensive as they aer precision made parts. But they do last a long time after replacing them. Check on your float jets (jet that is under the white float with the rubber pointed tip) when you do carb servicing. These jets are prone to wear faster than other parts.

what's the milage to send for servicing or when what thing happen dan need to send for servicing?
Recommended once a year or 30,000km whichever comes first.

fazli bro which bike shop u recommend to service our carb? how much any idea?
I would recommend Combine Motors at Sin Ming AutoCare Level 2. Look for Ah Hock or Ah Keong for advise and service of carburetors.

Bro hw much for the charges?

$80 for standard cleaning and balancing + some of their extra services like lubing cables and adjust your chain lar... If need to replace parts additional cost lor.

"What goes around, comes around"
Yup, we should do annual servicing lol..
I did mine when I just took over the bike..
LOL spent $500 to change the internal parts..

Wow..$500?...i thought i did mine at $232 is already ex...i guess mine is not that bad....dun tink it helps to decrease my FC...need to think of something else..
I wanted to change the world. But I have found that the only thing one can be sure of changing is oneself.
does anyone know why my bike feeling like choking and have morning cold start problem after service + tune + replace all 4 jets valve? the rpm also very unstable?? thanks
its cool to be unstable, it SHOULD drops under 1k when its cold but above 1k when its warm up.
if your rpm is above 1k when its cold, meaning your timing is out. same theory as class 2b bikes if timing high = easy kick start = consume more fuel = higher wear and tear.
so after warm up if its still unstable then you probably need to see the mechanic again.
when warmed, rpm is ard 1.4-1.6 but the needle very unstable. when cold, rpm is ard 1 so when start engine that time, the bike is like choking (petrol doesn't move smoothly) and keep on die off until i rev and rev it.
my fc still quite alright, 24km/L.
i dun understand the timing mean? = higher wear and tear>?
Maybe not synchronized or balanced properly for your carbs. A well balanced carb will not fluctuate so much in the rpm. Will stil fluctuate but not so much cos carbs are mechanical and EFI are elctronics controlled.

Right now, my needle will always stay at 1RPM, no matter cool or warm. How?
Your rpm suppose to be stable when your bike is warmed up or normal operating temp.

i would like to let you guys in on an experiance i had recently with a particular bikeshop near TP HQ.
this shop owner is very well-known for his hands on carburator and i have been there a few times through the years. but recently in particular, i left the shop with displeasure and as a dissatisfied customer swearing never to head back there again.
my bike was sent for bi-annual synchronise. carburator washed was done 6 months ago hence this time was only synchronising. he insisted i wash the carburator which i declined. after synchronising and on the way back i experianced mini-backfires when engine braking; definitely something amiss. cost: $40.
when sent back the following day, he retorted that its because of the carburator and in a sly way suggesting to me to open up the carburator and wash, which i then agreed - since it would probably fix the problem. whilst doing, he asked whether i would want to change the spark plug which i declined since i've already done so a month earlier. AFTER everything, i took it out for a spin and problems was not rectified BUT instead backfire persisted and spark/flame was seen during engine braking and acceleration. i sent it back to C. and he told me its because of the spark plug saying, "the first time i hear your spark plug, i dont like the sound already. something surely wrong. maybe from yesterday until today spoil the plug. not my tuning." i refuted back if he had known why didnt he check in which he replied, "but you say you just changed mah". i told him to retuned but he told me to get my spark plug checked first. coz if its the spark plug, i would only waste his time. and he closed the shop. cost paid: another $90
swore to his incompetency, i pushed my bike to HKL where ah huat checked my spark plugs and all four were ok. great even. he tried to resynchronise which backfire still. i ordered him to check my carburator again which he opened + washed and put everything in place again. took it for a spin and bike sounded healthy. no backfire whatsoever, just like before. cost: $90 (but satisfied)
C in many is undoubtedly good, but he did not render assistance to rectify the problem i had. and what HKL did was the same to any carb cleaning and synchronise: to open and wash my carb and synchronise and THAT rectified the problem! it could only mean his JOB in doing the above was not properly done! in my opinion he was already reluctant to do my bike as most repairs/service werent from his shop and in the first place i only wanted to synchronise. his prudency, needless to say, was limited.
never have i ever blacklisted a shop until now. for strong supporters of Kay&Tee, no offence to your beliefs. but we bikers deserve to share their pleasant and unpleasant experiance(s) with one another.

Very illustrative.
Could have done it at Combine Motors like I suggested above. Mine has been a year and its still running good. And I believe you've seen and heard my bike... Expensive lesson learnt seh...

is the FC that bad?
like duh...
Thrash? Don't mind if i do.
Bigger bore carbs mean more fuel and air goin in to burn. So I guess you can start doin the maths... My maths a bit lousy.

do u guys know what carburetor is fitted on the spec 3??
keihin or mikuni??thankz!!
I'll definitely recommend going to planet for carb servicing. 2 weeks ago i felt my spec2 was very weak and throttle not responsive. felt like its always trying to climb up steep slope. decided to go planet to take a look. the tall and thin mechanic (i dunno his name) was the 1 doing it.
in the end replaced 4 needle and 2 main jet things. not sure what are they. 1 of the needle is already broken. and apparently previous owner changed them before. 2 needle was "35" and the other 2 was "38". the mechanic changed all 4 needles to "38". and the 2 main jet was changed from "102" to "105". Also replaced some torn o-rings, and did a cleaning and tuning of carb. Total cost $230
True enough to what the mech said, the bike is really strong now, very good throttle response. I didnt really care about the price, whats important is the worksmanship and end result! Definitely a 5 star job!! Highly recommended!! shiok shiok!
on a side note. the 300km clocked after this servicing gave me a FC of 22.95km/L. need to monitor further =D
my lovers. cb 400 & sprint 1050 gt
i think its normal for 2 needle - "35" and the other 2 - "38". mine are of those sizes too.

Hey guys just I just got a Vtec 3 and I am very happy(my first 2A bike). However there's something bothering me. My idling does not seem very stable. I can understand from a cold start the idling might not be so smooth. And true enough once the engine heats up the idling seems a lot more constant and smooth. However at low rev just above idle the engine seems to be "pulsating" if you know what I am talking about. I can hear the engine seems to be going up and down and I can feel the vibration not being constant. It's very noticeable, and it sounds like the engine is going to stall yet it's not. This happends around 1500 to 2000rpm. So on 2nd gear for example in a carpark looking for parking space at low speed, my bike would keep jerking.
Anybody have any idea if this is normal or is there a problem with the carbs tuning or sync?
Get your carbs balanced and tuning of air screw. Mine also same. I can recommend Combine Motors @ Sin Ming Autocare. Look for Ah Hock.

Hello all, im riding a VerS. I feel my bike very sluggish and throttle response poor i.e. I need to throttle hard to get bike to speed up or pick up when starting from stop position. Any idea how i can rectify this?
Ive done my carbs when i bought it in 2009 April : Service $60, carb joint x4 $48, needle valve x4 $60.
Ive read somewhere recently that a company is providing clear carbon service for bikes/car so am also considering wherether that can help with my bike prob too. any opinions on this?
I occasionally go sumwere ulu 2-3 weeks once to clear my pipe by full throttle in Neutral gear to clear carbon. Is it okay todo that? Im just worried i may damage bike in throttling full in Neutral gear.
Thanks for ur kind replies!
Bro family guy, you can try to do grounding. It will improve your throttle response. Well, it did for mine. For pick up, can change to a bigger sprockets. Check out the chains thread for specific sizes. High revving ur bike for a few seconds is ok. It's like sprinting bro. Our body can't sprint for a full minute right. And also can do valve clearances.
When I feel sad, I stop being sad and be awesome instead. True story. Hehe

bro our body can sprint for full minute! tested and proven in ARMY.... the 60 seconds sprint and 120sec rest..
LOL! Sorry bro.. I not fit lehhh.. Haha!bro our body can sprint for full minute! tested and proven in ARMY.... the 60 seconds sprint and 120sec rest..
When I feel sad, I stop being sad and be awesome instead. True story. Hehe
icic...grounding- is it done by Ah Pek aka William with that meter thingy under ur seat? and bro what bout valve clearances? how do u do that?
Bro.. Hw much does it cost for grounding n which bike shop do u recommend?.
Yes. Ah Pek does grounding and some my friends are using his grounding. You can PM him but I think he's on holiday leh for now that's why so silent.. hehe. However you can also try other brands like the raizin and revtec. For valve clearances, if you know how to strip your bike engine components and put it back together, then only you can do the clearances. Otherwise, bikeshop is the best solution. You can read about valve clearances at this thread http://www.singaporebikes.com/forums...ces-when-to-do. (I dunno how to do hyperlink. lol!)

Well, go find ah pek. His is cheaper and reviews are good. A couple of my friends are using his grounding. But just to let you know you can also get from bikeshops. Personally, I'm on Raizin voltage stabiliser plus grounding and I got it from Unique. I spent 138 altogether.

ah yesyes i rem now...AhPek mentioned he gg short holiday this period when called him the other day... btw, grounding will increase ur FC is it?
Only if you whack harder because the response is better. lol!

Guys, my bike got kinda "lag" when moving off from stationary. Is it the carbs problem and need to clean/service is it?
