valve adjustment on scoot By silverfox96 (Read 884 times)

Like I said in my other thread, I was just tired of hearing those rockers clattering, so yesterday I went to the garage and tried my hand at an adjustment. Not too much problem, at all. I did find out that if I had small Chinese hands it would have gone much better. LOL! Everywhere I see that the valves should be set at .004 and .005, standard. Once I got the cover plastic door off and the valve cover, the exhaust was so loose that it appeared to be 1/32" or more. The intake was way too tight, to. I have recently purchased a set of metric feeler guages. The manual (arrow) stated that the valves should be set between .08 and .12 mm. So I went with a 10mm, hoping to get them right in the middle. What a PITA! It would certainly be an advantage if one had a wrench that had a teeny tiny square adjuster inside it. After about a zillion attempts, I finally got both set at 10mm. I had taken the plug out to feel the compression so to get the piston at tdc. Really didn't need to do that. All i really needed to do was observe the cam lobes. I have very little feeling in my hands, so getting the plug back in was a real chore. I finally gave up and walked down to a neighbors house, who does some wrenching, and asked him if he would mind coming down and getting the plug in for me. Took him about 15 seconds to do that! Well I got everything back together as it was supposed to be, and hit the starter. I couldn't believe the difference in the sound of the engine running. I could actually hear things other than that clackity clack! Well the next on my list is to find a nice chrome cvt cover to replace the grey painted on that came on the scoot. Guess I've done enough rambling for now.
