I noticed a few stuff that may need attention to prevent bigger damage.
My bike is a 2003 DRZ-400S that did 15000 Kilometers.
The problems are:
1) The engine ticks, I can't figure out from where exactly the noise is coming.
2) Sometimes when I lower gears (from 3rd and below) It doesn't work. I press the gear lever and the it turns, but not lowering the gears. Only after a few times it works again.
3) when I put in neutral and release the clutch lever, another noise I don't know how to describe is added to sound of the bike
4) If accidently, when I change from 1st to 2nd gear I don't pull the lever enough and it goes to neutral, after I press again the clutch to change it to 2nd gear and pull the lever more, I hear an impact sound from the gearbox.
normally if it happens I slow and then pull the lever and then its OK.
Can you please help me from your experience?
