Weight of 150cc bikes

Well, there is no denying the fact that pulsar, unicorn, hunk, extreme, and gs150r are all too heavy bikes for 150cc engine power. Yamaha SZ-R with kerb weight of 132 kg has shown that even a commuter bike can use new-age lightweight materials in side panels, etc., and still be durable. High time suzuki concentrate on improving power-to-weight ratio of their bikes.

An ammeter is a measuring instrument used to measure the electric current flow between the source and Load.
Here i can see the amount of charging current to the battery and discharging current from the batter to Load

Ammeter is a Bullet's one, Specification (-8A 0 +8A)

I made a cylindrical iron housing and inserted this Ammeter(as it is clear in the picture in my last before post)


cost is about 120 rupees

Note: I am sorry if some science Theory is missing here because i said in a simple manner

Hello Friends

Here i added two images that shows the charging current in my GS

1. At Ideal RPM the ammeter shows around 3Amps




2. At 3.5K of RPM the Charging current is more than 8Amps as in the below image




Note:This is archived using a simple Engineering modification in the Stock Coil without rewinding

Can you please explain the engineering modification done on the coil by that TVS mechanic? The negative reading of an ammeter means the bike is using more power than it produces and this excess power is drawn from the battery and it is getting discharged. That was the condition of your bike yesterday.

Now, after this mysterious modification, it seems the battery is almost empty because it is not getting charged while you ride with the headlight switched on which is connected to battery.




After that, revert to the original electrical connections until you rewind the coil and replace the RR unit.

This modification is Planned by myself and That TVS guy modified as i said.

Yes Your are right. That was yesterday plan and every thing by that TVS guy


Sure I am very interested to Share this with you all, but please i will explain you today evening because now i have go to a city called Coimbatore urgently for personal reasons, will back in the evening and give you the details



No my friend before taking this Images i drained the battery, because when the battery is at fully charged condition then this Ammeter wont go positive side, so what i did is switched on all the lights to discharge the battery, it took about 2.05 hrs to fully drain the battery.

Now i think you can understand what i am trying to say

+1 to vishnu

@Arulfast

Before rewinding the coil please calculate the power requirement so as rewinding can be done as per.

Power needed = power discharged from battery

Power produced by coil and charging (rr unit) of Battery should be higher and faster than the battery draining speed at the same time it should be with in the battery charging limitation.

55 is not a big deal for GS in ECO mode... In PWR mode I am getting 50~52 KMPL..also mileage depends on lot of factors....
When I drive at 80 to 85 km/hr...then I get 42 ~45 .

Ammeter

@fireGun

Hi Buddy,

Can You Please Tell ME from Where Did you Bring the ammeter,

And Where Did You Connect it on the bike....??

And What was the mysterious modification done by you.


Please let me know ???

Thanks

That's right,

Let me tell few factors that affects mileage.

# Driving style
* Using clutch more often

* Unknowing using clutch

* Unknowingly pressing back break while driving.

* Using clutch to increase speed rapidly

* Usage of accelerator (should increase speed gradually no vrooom vroom vrooom style)

# Driving condition.

* Optimum mileage achiving speed can't be maintained on pothole and uneven surface so called road.

* slow moving traffic condition along with so many speed breakers and as many as signals, typical indian city.

# Rider, pillon rider / load

* your weight + pillon rider or the load (things) you carry does matters and plays vital role on mileage.

* example bike weight 140 kg + avg weight of rider 75 kg + pillon rider 65 kg + loads 25 kg
Total weight 300 kg

Under ARAI testing bike mileage was tested with 140 kg + 65 kg rider so with 215 kg they achived 65 kmpl on test drive in long ride on clean neat highway.

# parking, maintainace nad fueling station..

* parking in direct sunlight or in a place where the temperature is high cost fuel at least by 1 or 2 kms if you do that daily.

* on petrol tank if space occupied by fuel is lesser than the space occupied by air will contribute more to petrol evoporation.

* maintaince doesn't meant only wash and make her shine, hope most of you know much on how it impacts the vehicle perfromance and mileage
Example chain slackness, periodic carb cleaning etc....

* At the max try to reduce the refuling frequency (I mean fuel it once by filling the tank wiht more petrol (either full tank or maintain 10 ltr in tank)

* Most of us know the petrol bunk thiefs who feed less petrol but petrol bunk meter shows correct reading.

* At most try to fuel at one bunk always and make sure that bunk gives correct quantity and quality petrol. (Most of the company owned bunks are good)

Today i switched to Motul 3000 4T 20w40 oil. I got it for 240 bucks. Is that normal price?

knock knock.. A new owner here

Guys,
Joining the group of proud GS owners..

Today evening i was delivered my 1st bike. And I'm proud to say, its Suzuki GS150R with a grey shade. Did around 25 kms today. Enjoyed the ride..

Will update more shortly. Lemme have the complete feel of this amazing machine first

I got the Motul 3000 4T Plus 20w40 oil for 255rs.

Yes, 255 is the MRP, but i got for 240 bucks

Guys,

Yeah I purchased the 15W-50 motul @ 225, yes mrp is 255.

Have you guys utilized the sticker offer, they put a lable behind one side of the motul bottle sticker, you can find the bulge on the lable peal off the lable to find the offer sticker what ever the amount mentioned is the discount price.

On old motul bottles the offer lable is inside the motul bottle it may struck at the bottem of the bottle, after transfering oil to your bike take out the offer lable (safely placed inside a polythine cover) give it to the dealer and get the specificed amount as cash back.

Enjoy your ride.
