    Cool Sprockets ''35 15''

    After much hesitation and a lot of thought i finally decided to replace my genuine sprockets 41/14 with 35/15.

    Installation
    Well the installation was fairly simple, obviously the chain had to be shortened. Although the amount of hammering
    involved (''USTAD''), i was afraid the chain might get a little weak.

    Experience
    My experience with the new sprockets gear wise.

    • 1st = Definitely more longer than previous, however a very slight reduction in speed. Shifted to 2nd at 30km/r




    • 2nd= Very slight or almost no change, very minutely longer. Shifted to 3rd at about 55km/hr




    • 3rd = Now this is where the magic started, felt the real power of the engine the bike almost shot. On stock the 3rd gear was almost non existent but now it packed a punch. Went from 55 to 80km/h (GPS speed).



    • 4th = For a moment i had forgotten i had a 4th gear. However when i shifted to it the experience was not satisfactory bike got flat, it was cruising at 85km/hr, the RPM was quite low as if the engine was applying very little force.


    The maximum speed i got was 88km/h(GPS speed not the meter one) and i could maintain it relatively easily.


    Positives
    Phenomenal Power in 3rd gear.
    Low RPM in 4th gear

    Negatives
    Top speed not as much as i expected.

    However I am satisfied with it.

    Moral: No replacement for displacement.

    If you ride like there's no tomorrow, there won't be.

    You should change them, change the rear sprocket to 37 and feel the difference, for eg 37/15.
    Add a Cg 125 carb tunning the carb from a good ustad,remove the air filter fully.
    Change your current coil and cdi of 125 china or Honda atlas 70.

    Cheers !

    no mention of the bike ?

    i hope its chonda 78 ?

    few little mods:
    1: replace the pod air filter .. and get the best of both worlds . frew flow and engine prottection from dirty air. install it the way i installed it .. i had mad a post about it .. thats sweet.


    2: buy an aftermarket qingqi 100 carb and use intake pipe of suitable width and match its openings with that of the carb mouth .. you will get a lot of power.

    3: replace the head gasket with thinner head gasket. if its fiber head gasket replace it with so called janyan mettalic one .. the mettalic one in stock condition is very thick as its 4 metal sheets . just use one or two of them

    41/16 The best setup I experienced:
    Recently I changed my front sprocket to 16 from 14. The front sprocket is stock (41). I have a Chonda 78cc and the result is awesome. As i live in Karachi, pillion riding is usually banned therefore on a single person's weight the bike feels great. The vibration is gone. The top speed has increased. 3rd gear is where I experience the biggest power band of the engine. You feel a slight decrease in torque when you engage the 4th gear but you will get use to it.

    Changing the sprocket not only increases performance of your bike but also saves you fuel. Try it!

    do nothing.....just change your front sprocket from 14 to 16. I it cost you Rs.200 with labor cost and its a 10 minutes job maximum. Better fuel economy and less vibration is guaranteed.

    I too had a CG 89 for quite sometime, however I never felt the need to replace the sprocket set on it, therefore I cant guide you in this matter. Obviously altering the final drive has its pros and cons and if you alter the stock setup you will loose the acceleration but will gain higher top speed and lesser vibrations while cruising.

    Im running on 16/41........have tried 15/41 too however the difference was negligible. I prefer the 16/41.....the difference from stock is evident. Obviously pickup thora hurt hota hai but I got use to it and now I cant ride a bike on stock sprocket......... They feel under powered.

    Torque reduces as you increase the gears.......... with altered sprockets the overall torque of the bike decreases hence reducing the acceleration of the bike. As 4th gear has the least torque already and with altered sprocket it reduces even further so feel a power decrease......its very evident.......but if your gear shifting is precise .... the difference in acceleration is something you can live with easily..........3rd gear may power band acha hota hai engine ka and it produces highest torque therefore 3rd feels great.

    For longer routes and highways where you need to cruise at decent speed.....an altered sprocket setup reaps its benefits. Lesser vibrations and better fuel efficiency. Not recommended for crowded routes.
