This thread probably could have been split into a few different threads, but these topics are somewhat intertwined. I bought a brand new 990 Adventure back in 2009. It was my first bike, and the only bike I have ever owned. I've been in love with it ever since. I've grown attached to this bike. We've been through some things together, and we've found things to do in stormy weather, and all that stuff. It has taken me halfway around the world, and I now have close to 100,000 km on it. During a short trip last year, I experienced engine problems that I have yet to attempt to diagnose and repair (since I really have no idea what I am doing). My goal is to tackle this issue this winter and hopefully I can get the bike back on the road for next year. However, there is the possibility that I will not be able to repair it, and, even if I do, I am beginning to accept that this bike will not last forever. I saw on the Advrider home page that KTM will be licencing the LC8 to a Chinese manufacturer. This doesn't mean that we will see another 990 Adventure model from KTM. This more likely means that KTM is retiring the LC8 for use in bikes that it designs and manufactures. However, I would love to eventually see an updated version of my bike. The only thing that I felt that could be improved upon was fuel efficiency. This would likely require a redesigned engine, which brings me to my questions: Could we conceivably see a new 990 model in the future with an updated engine? What factors in the design on an engine affect fuel efficiency? Looking at the 990 models and comparing to the 1290 models, the LC8 is less fuel efficient than the 1290 engines, despite being smaller and less powerful. How long are parts for my 2007 model likely to be available from KTM?
