I just put a fresh plated cyl and wiesco piston in my 91 yz 250 after an inccedent with a unruly wrist pin clip. The bike sat for 8 weeks torn apart while i saved money. When i reassembled my bike it idles really sluggish and it really smokes alot. The bike will clean out while riding and run great, but it runs really ragged in the low end, and it didnt do this before. The bike had the origanal piston in it when it blew and runs much faster now despite the low end problem. I can turn the petcock half off and it cleans up the idle alot. I tore down the carb and dipped it in carb cleaner and cheaked the jets and all is good, but no change it running. I removed my reeds and found my duel stage reeds had a gap between the pettle and the cage. Will a set off old wore out reeds cause a rich idle/ lowend condition? Any help is appreciated! :aj:
