runs rich with air correction

elmo » Tue Jun 14, 2011 5:18 am

hi all so ive recently fitted a rebuilt motor to my mc21 it has standard pipes and modified air box it has wire splice but i returned it to standard to run it in also its been wet all week here so thought i wont need any extra power.
while it was apart i set about fixing all the little things that were bodged over the years of previous owners including the missing tee piece and air correction plumbing not been conected
so i start it and runs fine but soon as i go for a rev it wont and just splutters at about 7000 obviously running rich so i take the air correction hoses off and it runs fine.
so to my understanding some one must have rejetted the carb's right!! or it would be way lean with this disconnected ? would'nt it so my main question is
is there some trick were the carbs are rejetted without these hoses connected.
or do you think it has been done to save finding the right tee piece
in the end i just want to know witch way i should go leave it as is cause it runs fine or spend the time to revert it back to how it should be.
any and all advice would be much apreciated ahhh "MATT" "stevenrc45" some one who has spent time testing both setups HELP
