I have a GPX and I am warming it up according to the owners manual â€“ 10 to 30 seconds depending on the ambient temp.. As soon as I put it into first the bike jumps forward and stalls. I would normally assume that the clutch needs to be adjusted but it only happens when the bike is cold â€“ as soon as I get going the bike changes gear perfectly.. even into first when I am taking off from an intersection! Is this due to the wet clutch system? Do I just need to warm it up for longer? Or does the clutch really need adjusting?
