I am having YAMAHA YZF r15. I am facing starting trouble at times, Also i am feeling some missing when i am trying to accelerate. Some times bike would stop and wont start for hours.
Top speed and acceleration has considerably decreased. Earlier i could easily touch 134kmph. Now its very difficult to go above 128.
My bike is 3 years old and it has run 18k Kms.
My chain is also very loose. Even if i tight, it will go loose after few weeks.I have changed my chain and sprocket at 13k Kms.
Could you guys tell me what all I should check.
