I am considering buying a new KLR, and have been studying the machine for many months and wish there was good answers to these 2 main troubles.
1) I never had a car or bike with oil consumption problems, and the cylinders of a 650 are not any bigger than those of other big twins such as 1250s. I have a theory that the problem is due to low detergent low quality oils which plug the orfices in the oil ring and piston. Thus, oil is pushed up into the combustion chamber instead of dropping back down into the sump from inside the piston.
2) I can't imagine that the engineers behind the Ninjas are so stupid that they keep a failed doohickey design for 30+ years. I think people are not understanding something about the balancer chain assembly and how tension is maintained. As I understand from reading, the spring is only relevant when adjusting the tension, and it isn't necessarily a problem if it is without tension otherwise. There are also many complex factors when thinking about the system such as wear on the chain guides, rotation of the crank, wear on sprockets, lengthening of the chain, etc. And I have read so many theories and fixes that my brains are a mess. Is there no definitive maintenance spec for that system in the service manuals? Does wear of the guides cause slack in the chain which gets blamed on the doohickey/spring? Is it possible to take a link out of the chain if it gets too long? Some people never seem to have a problem with the doohickey/spring, so does anyone know why some do and some don't? I can't imagine that after 30 years, there is no official Kawi service instructions for maintaining proper functioning if the balancer chain system, or that such instructions would be ineffective. Is this really the case? Has anyone read the service manuals?
