Adjusted valves
« on: November 17, 2008, 08:04:02 AM »
I attempted to adjust my valves before I went out and rode this weekend.  At first, the bike acted soggy with a noticeable loss in power.  So I thought they were to loose, but as the day went on after each ride, I could feel the bike respond better.  ???  So I'm a bit confused.  I'll go back and re check the measurements.  It ran strong before I tinkered with it.  Might go back and tighten them up a bit.  Thoughts?  :help:

Stock Cam?


What did you set the intake and exhaust to?

Stock cam, and when I checked before I adjusted, they seemed tight.  I put the intake at .11 and intake at .18.  I think I'll take them back to .09 & .16mm.

Stock
     Intake:       .005" ~ .13mm
     Exhaust      .008" ~ .20mm

These are the stock specs. I'd check whether or not you were using inches or mm. I almost set mine wrong when I did them @ first. :thumbs:
