I have the money and am in the market for a new bike. I recently stumbled upon this gem http://dallas.craigslist.org/ndf/mcy/4027876247.html I have ridden alot of dual sports, and also have a dedicated trail bike. I have seen many WR and CRF conversions done but I am curious to know from those that have done it themselves or know of others who have. Am I going to be checking valves and shimming every 50 hours? I mean if I do the 16 mile round trip to work every day, then hit the trails on the weekend, am I going to be spending the rest of the weekend checking valves? I am mechanically inclined, but have never had to do it on my DR or DRZ. Would be a worthwhile replacement for both bikes, or should I just stick with 2 bikes?
