I have a loss of top speed and rpm. Low speed and power are good, A little more vibration on acceleration than before. I have changed the needle setting both directions, checked muffler for problems, changed spark plug and cleaned air filter. I have good compression! (Slat head,and tough to start with out skidding rear tire) So far still no difference. It acts like I am in the break in period again 16:1 (I run 25:1, Had it for a few months) I used to be able to hit 35mph + on a good day! Now I'm LUCKY to hit 21mph And 4 stroking alot when it reaches its max) Any one have any ideas on what to check next? Or did I wear it out already? Could I have got the RAW deal I have read about in other threads?
