Hi Friends,
I have got a very technical question and would like to have some knowledge on this. As we all know opening the throttle from idle to max increases fuel input to the engine. Throttle = Accelerator in Indian terms.
Now the company (tvs for my new Jupiter in my example) specifies that new bikes until 1000 km have to be ridden in the speed of 40-50 kmph but I have a question that if I drive on a road which is slightly sloped downward or straight and its empty , then over a period of time be it a geared bike or automatic scooter, the vehicle picks up speed even in less throttle and I observe that even with 20 degrees of throttle, the basic one, my vehicle reaches speeds upto 60 kmph. Though the vehicle speed is reaching 60kmph but the fuel mixture being sent to engine is less and also the revving is not harsh. Now I know you all have got confused on what I mean when I tell 20 degrees of throttle. I will explain, keep the throttle at idle position and mark an imaginary point on it, then move the throttle upto fully open position, and calculate the degrees which the point moves. Internet tells that the degrees which a throttle moves is approx 80 degrees.
Refer this pic:
At idle speed the throttle is at 0, if you revv the throttle it goes to 10,20 degrees so on. Rarely in my 13-14 years of driving have I driven at throttle more than 50 degrees. Mostly I drive solo and drive very defensively, so don’t go harsh on the bike.
There is a relation between speed & throttle & road conditions, if the road has a steep gradient then to reach 60 kmph on that road, I may need throttle of 60 degrees also, but I am driving on straight long smooth tarmac roads.
My first query is if I drive my new TVS Jupiter at 60kmph but the throttle given is only 15-20 degrees considering the straight road and me driving solo, will it affect the engine performance?
My second query is do bikes really adapt to the driver, driving the bike. I have a hero Honda super splendor a 125 cc bike and when I drove my friends 100 cc spelendor bike I found his engine more refined and having a very good pickup. Might be I have driven my bike for 10 years at speeds not exceeding 60 kmph and also solo, and he has driven his bike on good speeds / with pillion. How to identify that which method will make a bike more refined and responsive to the throttle. I wish to get more pickup from my bike.
