Ok, I bought a 07 ktm 505sxf about a month ago, that appears very clean. I'm not familiar with working on ktms, so I have a few questions. I have put approximately 2 hours on the bike since I got it. It has never started very easy hot or cold (even with it turning over fast with the battery charger). The last time I rode it, It took me awhile to get it started and now I cant get it to start at all (wont even pop or try). The only work I have done to the bike is oil/filter change, clean airfilter. The bike has great spark. The previous owner claimed the shop adjusted valves right before I bought it, but I thought I should check them to be safe. I have taken the valve cover off, and got it to tdc and thrown a feeler gauge under the cams. Left side ex=.006 Right side ex=.010 Intakes both were .007. The left side exhaust lobe and follower has visual wear but feels smooth to the touch . The cams almost appeared too dry to me like they were lacking some oil in the top. I know the exhaust valves are out of spec but shouldn't it atleast attempt to start? Whats the best way to ensure the top end is getting a sufficient amount of oil (im running moterex 10w50). Also, what do you guys think of the 505's engine performance? Im a little disappointed to be honest. My stock 05 crf450 will eat my 505 from top to bottom.
