I replaced my camshaft and rocker levers, redid the top end, set the valves acording to spec .004 (int) .005 (exh) ran the bike about 100 miles, engine was running fine but I thought I would reset the valves and to no real surprise the settings were a little loose about .008-.010 I figure new parts breaking in,so I reset them to spec .004 and .005 and took the bike for a ride and had a noticeable power loss slower acceleration. So I reset them again and increased the clearance back to .008 and .009 took the bike for a ride again and power is back much quicker acceleration. Has anyone had any experience in this? or have any ideas?. There are no performance mods done to this bkie except for Super trap exhaust, I'm not sure what the stacking is in the silencer I bought the bike with it on.
