    Hi bros. Was wondering, will it be cheaper to purchase our own carb rebuilding kits then sent to shop for fixing, tuning and balancing?

    i just came back from KNT. did my carburetor cleaning and tuning. cleaned my air filter as well. good service, bike feels much better and more responsive. clifford also highlighted a few parts of my bike that needs servicing which i will do in due time. will definitely return here again. total damage.. clean and tune carb plus replacing all four rubber hose connector to carb plus clean air filter $170. decent pricing.
    Thrash? Don't mind if i do.

    If i'm not wrong bro, i spent 60 bucks to wash and tune the carbs. The pins cost about 20++ bucks each. Total 4 pins. Pardon me if i'm wrong, cuz it's been quite some time ago since i've rode my spec 1.

    Eh, if you can find online the OEM rebuild kit I also thinking of doing the same. I'm starting to buy on my own the OEM parts and send to shop for their service.

    Kenso jets... I'd recommend it to someone who has done major enginework. Bigger bored block, bigger pistons, race camshaft, etc.. Otherwise dynojet kits are the more reasonable option.

    But the kits mentioned for the stage 2 is for those who have only done aftermarket air-filters and exhaust systems... That's why they call it the Stage 2 Kit. You used the Kenso Jets before? Would like to know more bout it from user feedback...

    they mention it was for aftermarket air filters and exhaust systems... but in actual fact dynojet is sufficient. like i mentioned before, the jettings are more for engine based modifications. i've seen plenty of riders switch from kenso back to dynojet... cos its not really fuel efficient. for the extra vroom... go right on ahead if your pockets are deep enough

    i think you should go and check and service it. probably the floating jets are worn off due to wear and tear and the 4 rubber connectors via carb to airbox surely broken down already. you'll feel the difference after servicing.

    Anyone can recommend any place around Ubi or Tamp industrial park to service my Ver.S carb? How much would a basic servicing cost? Thanks.

    By cash? LOL...



    Anyway, service+tuning carb = 80, clean air filter = 10, change normal spark plugs = 10x4=40, but time taken = approx 3 hrs *sweat*... I know paid for the service more than other shops, but still prefer my trustworthy mech... hehe...

    Hi bros,

    Thinking of servicing my spec3 carb. Cos pull throttle feels a bit heavy. My friend told me spec3 service carb and setting need to use computer etc to set. Is it true? If yes, where is the best place to do?

    I think your friend is talking about doing dyno. You can go to HKL.

    What's dyno? Any idea how much it cost and if it will help in the FC?

    It's a computerised process of tuning and balancing the carburetor. A good tuning/balance of carbs will ensure maximum fuel efficiency. Unless you're using stage 2 and above main jets for your carbs. However, there's a lot of factors affecting the FC. Weight of rider and pillion, Sprocket size, Engine oil quality, tyres condition, Style of riding, etc.

    So the dyno tuning not really necessary when servicing carb? Btw Leo, FC is fuel consumption.

    I believe is a must for tuning your carb after servicing, like what Rider Saje said. But I'm not sure about the Stage 2 and above main jets thing. Is it gotta do with the higher power output from engine which leads to higher FC? Mind to educate us, Rider? Hehe...

    Jetkits like Dynojetkits (It's dfferent from Dyno run) is used to enhance your carbs which will increase performance.

    I got this from Racewerkz thread. Diclaimer: Not advertising for them though.

    STAGE 1 Jetkits
    Intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N. Stage 1 kits are designed to improve throttle response and driveability and in most cases power increases of approximately 5% throughout the entire power range can be achieved

    STAGE 2 Jetkits
    Intended for motorcycles with a stock or mildly tuned engine using a well designed aftermarket pipe with a modified airbox and a stock replacement air filter. Stage 2 kits are designed for applications where individual filters cannot be installed and for applications where airbox modification improves the engine's performance. In most cases power increases of approximately 8% can be achieved.

    STAGE 3 Jetkits
    Intended for motorcycles with stock or mildly tuned engines using a well designed aftermarket pipe and individual air filters. In most cases power increases of 10-15% can be achieved. However driveability may be compromised particularly with short stroke, high rpm motors. On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise driveability, in such cases stage 3 kits are not available.

    STAGE 7 Jetkits
    Intended for race only use or for special applications, like the Yamaha V Max complete induction kit. Stage 7 kits are designed to optimize jetting for a given tuning specification or racing conditions.

    information provided and also available at Dynojet website

    if i remember correctly, the pins are 20/ piece. if not spoil dont anyhow change. go to a reputable mech to service your carb.
    When touring, its usually the rider that give way first before the bike itself.

    got box got tour.

    Nope, dyno which also means dyno-run just produce the A/F ratio & power/torque results from the dyno-run.
    Based on the results, re-jetting will be done to fine-tune the A/F ratio to maximised the performance of the bike wifout excess fuel used.

    Dyno itself dun change or alter anything to the bike.

    For EFI bikes, Revo for example will do dyno-run when fixing a power commander as the dyno results are needed to produce a mapping to be loaded into the PC for maximised performance and balancing the A/F ratio.

    Dyno-run is not necessary unless you wanna know your exact A/F ratio and further fine-tune your bike.

    Tuning is a must, or even changing the jetting size if you have changed to a aftermarket exhaust system & air filter, must be done to balance the A/F ratio for maximised performance or else the bike will be running very lean.

    The different stages of dynojettings is to suit the bike's modifications for maximised performance and balanced A/F ratio wifout compromising the FC.
