Just bought a Yamaha super tenere but bike seems to be having a timming problem after 2 to 3 km ride.At idle RPM from 1000 would go to 1300 then down to 900 and up again.Been back and forth to the workshop after short run left bike with workshop a day or two.Latest is 1 week with them.Hope this time they solve the problem.Going back to the workshop due to one month gaurantee.Any suggestion would be appreciated.
