From one month, i am facing a problem with my Suzuki Sprinter. Almost twice a month, i use to go to my home town by bike (distance about 107 KM). My problem is that after 70-80 KM, my bike start knocking (engine try to turn off with phat phat sound) when i decelerate / braking, but on acceleration, it is ok, just above 30-40 KM/H speed.
I checked from Suzuki Fsd. but they only tune-up the bike and nothing. I also changed the fuel from Total to Shell but all in vain. Other than this long trip and 1-2 days after trip, bike perform excentely.
Normally, i am a bike caring guy and change oil etc. within 1200 km.
So, i would really appreciate if experts of PW could help me.
