I am currently running B&S World Formula with a titan clutch(7 2005) on a Maranello frame. My issue is when I hit about 45 or so there is a chatter / shutter feeling you get in the rear of Kart I am trying to figure out what it can be, but it is consistent. I am new to Karting so I figured I would ask around. the clutch looks to be fine and again it only happens at about 45 miles per hour, but feels rough.
Thanks for the response. I Do not think that is issue – note it happens for about 1 second and then goes away. Almost like if you were going over rumple strips in road. After the 45 it is gone. It is very consistent, but only for short period of time.
some kind of problem with balance – wheels or otherwise. If it’s consistently 45mph it’s some sort of resonant frequency caused by rotational parts – engine (rpm), clutch, wheels, brakes, chain, sprocket, etc.
Or, if you happen to be at 45mph at the same point on the track each time, it could be track related.
