Drz400s Rough Idle

Recommended Posts

Hi, my Drz has had a slightly rough idle since I bought it. I thought it would be the valve clearances so I've done those now and both are in the upper spec range. I will attach a youtube video of the bike running if anyone could have a listen and see what they think it could be?

Thank you everyone!       Youtube Link:

Loose/stretched cam chain can cause loppy idle.  Tight valve lash can cause hard start.  MCCT allows you to adjust cam chain tension.
