    Default Improving the Performance of you Suzuki GS-150

    AoA Everybody.

    I would request all Suzuki GS-150 owners to discuss typical performance issues with their bikes and how they resolved them. this way, we'll have a collection of information here for the benefit of newbies such as myself and hopefully, other bike owners will also profit from it.

    Improving the Performance of you Suzuki GS-150 - Pic3 zps51edbf85

    Following problems/issues has been identified so far:

    1. Less than ideal performance of the ignition system
    2. High tendency of the bike to break speedometer and rpm cables.
    3. Loud (Tuck!) noise from rear wheel and less than ideal gear shifting.
    4. Faulty/Finicky fuse.

    Poor performance of the ignition system:

    Improving the Performance of you Suzuki GS-150 - Pic5 zps6f7688f3

    The factory /EM coil provided with GS-150 is not up to mark. I replaced it with Honda Deluxe's ignition coil (DENSO) and the quality of the spark improved. then I installed a platinum spark plug (NKG CR8EGP) and instantly experienced better throttle response and stable idling. on top of all that the bike's cold starting ability also improved significantly.

    Then I read an article where the author was recommending spark plug indexing in a bid to aim the open end of the spark plug's tip somewhere in between the intake and exhaust valve of the engine for better performance. BOY! it was some exercise but the results made it all the worth while. the throttle feels much lighter than before, the bikes accelerates better than before and the idling is as stable as the heart beat of a monk.

    now someone might ask why not Iradium? well....contrary to popular belief, Iradiums do not offer any performance benefits over Platinums. they just offer increased/longer life. so why spend three times as much when you can get the same benefits from Platinum plugs?

    high tendency of the bike to break speedometer and rpm cables:

    Improving the Performance of you Suzuki GS-150 - Pic4 zps2ae8ee70

    I was getting kinda tired of casual breaking of the speedometer and RPM cables. I know one is supposed to lubricate them with WD40 but somehow I was never convinced that a simple CLP (cleaner, lubricant, protectant) would be good enough for the job. the problem with oil is that it eventually migrates from the place where it is applied. Then I stumbled upon this:

    NASA Liquid Grease

    Its a solvent based lithium grease packed in a pressurized container. which means that it can penetrate to the desire spot then solvent evaporates leaving behind a uniform film of lithium grease. pretty neat concept. I bought one and sprayed down the RPM and speedometer cables. I was instantly sold. Now I use it on clutch and throttle cables as well. Guess what? the Speedometer and RPM cables haven't broken since then and clutch and throttle stay lubricated longer.

    Loud (Tuck!) noise from rear wheel and less than ideal gear shifting:

    Improving the Performance of you Suzuki GS-150 - Pic1 zps2f2cb105

    Loud noise as it turned out was from rear drum as the drum rubber was not a tight fit. just for the sake of killing a few million brain cells solving this problem I approached a guy who makes custom drum rubbers and voila! no more sound and the gear shifting is now as smooth as silk. I don't know how it made the gear shifting smooth but it did. now shifting the gear up and down do not produce any jerk or noise.

    Faulty/Finicky Fuse:

    Improving the Performance of you Suzuki GS-150 - Pic8 zpsc9fdb1c3

    The OEM ignition fuse provided with the bike is nothing more than an outdated piece of cheap contraption. I learned that the hard way. I was on my way (to nowhere) and the bike suddenly totally went dead on me. nothing would work. luckily, Suzuki Center was near and I took the bike there and it started without a hiccup. I moved on then one fine day it happened again. I took the bike to the same guys and the bike started again without any problem. then the mechanic told me that I should get the fuse replaced with a car fuse of equal ampere. I took the the bike to a car electrician who installed a proper car fuse and charged me just Rs. 100 (including the price of the fuse box and wiring) no trouble since then.

    Improving the Performance of you Suzuki GS-150 - Pic9 zpsf4ade752

    Anyhow, thats how I went about solving some of the issues with my bike. if you guys have identified any other issue and successfully resolved it, kindly do share with all of us.

    Regards.

    A small issue in my bike (Suzuki GS150)
    Bike has clocked 1700 km. While driving at a constant speed say 40kmph or 50kmph bike 'jhatke marte hai'. I am not doing anything with the throttle it just happens automatically. It's just like when you are running very low on fuel which is not the case coz bike has plenty of it.
    Engine oil is due for change at 2k mark along with tuning. Will tuning and changing the oil resolve the problem or some other work is required?
    Currently using Total 20w40 engine oil.
    Kindly leave suggestions as to what can be done. Thanks.

    nothing major, only 2 possibilities with this problem.
    1) battery terminal are loose, if u are using maintenance free battery with wire attached with horn clips to battery terminals than better get those terminal soldered with good quality wire and than join the those wires with bike own battery terminal wires.

    2) plug coil terminals underneath the fuel tank are loose and they do get loose as they are attached with horn clips with the coil.
    so ask any electrician do make them fast and secure them thin copper wire and masked them with electric tape. this way they will not get loose.

    i went through same problem and after doing above mention measures problem never occur back.
    use some time the mixture of hi octane with normal fuel as fuel we are getting is of real poor quality.
    oil grade is fine. summer approaching so use any good kind gasoline engine oil of 20w50. local oil do the same job in less price compare to any fancy name imported oil.choice is yours.
    Help others so that u can be Helped

    Dear bro!
    You're using very heavy engine oil in a new bike.Using 20w-40 in winters is like killing your bike.The "jhatka" problem is occurring most probably cuz of heavy engine oil.Your bike is basically choking,Change oil and try to stick with company's recommended 10w-40.

    My experience with Zic 10w-40 is simple marvelous.The sound is reduced..Very smooth acceleration,gear shifting became very soft..

    Congratulations. Which coil you have installed and what's the price of it?

    Bro, I am afraid I cannot help you here without knowing the exact nature of the sound. can you explain the sound? can you identify the point of origin? otherwise there are so many components involved that its practically impossible to pin point the fault.

    Regards.
