Running but still lean...w/reward to whoever diagnoses it

am curious what it means coated nicely means? also jeting higher ? you mean a larger jet? try downsizing the jet and then warm it up real good and adjust the idle mixture screw. do plug chops also

not sure about the filters on these scooters but gas on many elements destroys them .. the will not flow near what they should. i always use K&N cleaner or hot soapy water let it dry and and get the good spray stuff from honda to lightly oil the filter.no need to overdo it

i dont get it, that scoot i sold you had the variator restrictor plate removed, an 82 main jet, the hole punched in the air box, and the PO had drilled 3 holes into the side of the exhaust and it did 35... seems like you should be going a lot faster.
Re:
Never ever down size a jet unless you have done a correct plug chop to prove you are too rich. Not doing so risks a melted piston and a junk top end of your motor.happyman wrote:am curious what it means coated nicely means? also jeting higher ? you mean a larger jet? try downsizing the jet and then warm it up real good and adjust the idle mixture screw. do plug chops also

need to maske sure the exhaust is really clean to start with

Re: Running but still lean...w/reward to whoever diagnoses it
Wouldnt a plugged exhaust cause it to run rich. And I don't think WD-40 is the right thing to be using on the filter, Like someone said use the honda stuff, the manual will tell you what to use. In the spree manual it says to use 90 weight gear oil, which is a ton heavier than WD-40!!! And if that thing is anything like the spree, the airbox lid needs to be tight and the gasket in perfect shape. Also the hose from the airbox to the carb can not leak or it will run lean as *! And a drilled airbox would run lean too.
