with the piston at tdc , the cam should be aligned a certain way. the 2 small holes should run parallel with the head with the bigger hole at the top.

when you first checked the valve lash , what was it set at ? or did you just redo them without really checking .

if the chain tensioner somehow came loose , then it would be possible for the chain to skip a tooth or more. if the timing is off , then another valve adjustment will need to be done after setting the timing.

When it comes down to it , it may end up now needing a top end rebuild but its still not clear yet.

I'd def double check timing and valve lash.

Thanks, I thought the oil pump pushed the oil out of the dipstick cover. A clicking noise on the fan side could be the stator pickup coil has come loose, and is bouncing off of the magnet on the outside of the flywheel. I had that happen, and it made quite the noise. No prob, the oil pump actually sucks the oil from down below the dipstick and towards the valves. |

I believe that most big names businesses are more likely to sell genuine products other then small personally owned businesses. One good thing is if u buy from a place like Walmart , you can take the product back if it is junk , even if it blows apart after a few days of using . try that with most small online dealers. Its hard to find a reputable delear. I have one , but even then I was once sent a gates belt that was said to be the aramid " Kevlar type " but it was just a regular gates belt. They quickly sent a replacement and I was told to keep the other belt also.

I think my main concerns with running the engine at that rpm 8500-10000 rpm at any length of time , considering you would be running all out constantly , would be : I have yet to hear of anyone doing it and posting any results like oil temps or how long the engine lasted compared to someone running no higher then 8000 rpms. And also I can get the same speeds at 8k then one could at 10k so why do it ? I would just have some pretty justified concerns. I would never do it unless I had a donor engine to run it at those rpms for extended periods , or if I had the extra cash to test it out .

The one thing that still bothers me is " why did the scoot die in the first place ?" Weak or dead battery ? No , especially since its an ad cdi . bad spark ? Possibly . loose or bad coil/plug boot , possibly. Clogged air filter , possibly . bad carb diaphragm , possibly . another issue is why did the scoot not fire when u bypassed the carb and squirted fuel into the manifold ? Clogged air filter ? Possibly. Or bad spark, possibly . all reasons why the scoot would shut down while riding it.

I wonder if it's a weak starter or poor wires. Did it turn over faster? John Yes alot faster,the battery was definitely low but it still doesn't seem to be the root of the problem Can u check.the spark again and see if it seems like a nice strong spark ? A weak spark may also give u the same symptoms. If you can just replace the plug I would def do it. They are only a couple bucks . may not be the issue but at least it would rule it out 100% |

I even had the starter clutch cause the same issue on mine. I had a good battery and even tried jumping it , but the same thing happened. Could be why th scoot shut down also, the starter clutch " mine " was in pieces and sorta jammed up.

tvnacman should be able to help you with the voltage from the battery and stator .

It is ac Is there a guide to checking the battery and the stator with a meter? Not exactly sure how to, I'm going to try to jump it in a few hours I'm not sure how much you know about scoots , but some have an ac powered cdi and some have a DC powered cdi. This makes a big difference when troubleshooting this kind of problem . I've been concerned When it comes to why the scoot died while running. If the scoot has an ac powered cdi the scoot will run without a battery , but if the cdinis DC powered the scoot will die I the battery craps out . so why did the scoot die while you were riding ? That's the main question that needs answered. I'd like to see a pic of the spark plug if you can post one . We do know the battery I'd very weak and its def an issue . the scoot will never start with a battery that weak . I'm really anxious to hear how the scoot reacted to jumping it !! Hopefully it will start! |

I should rephrase that . u can go the other way , but you will be wasting the lower gear feel, and you will have a slower takeoff.
