bansheejoel Posted August 21, 2008 Report Share Posted August 21, 2008 well i finally got the time to do a leakdown test on my shee. I did the test twice and it held a perfect 6psi for 6 mins both times. I am at about 500ft above sea level running 380 mains, stock pilots, and my needle on the 4th clip down from the top and its still running LEAN. I took it up to the dunes once and it seemed to be running spot on. The next weekend i took it up after cleaning my airfilters and it ran lean as hell. Im running a 32:1 mixture. Any ideas or tips would be appreciated Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted August 21, 2008 Report Share Posted August 21, 2008 holy hell 380's? and your lean? do a plug shop and post picts if you would Quote Link to comment Share on other sites More sharing options...
J-Madd Posted August 21, 2008 Report Share Posted August 21, 2008 What makes you think its lean? If it is infact lean, and you don't have an air leak, go up on the mains. Quote Link to comment Share on other sites More sharing options...
Hilarious Posted August 21, 2008 Report Share Posted August 21, 2008 try running it with the choke on and see what that does. judging by your sig you are ported and i am assuming you are using stock carbs. Quote Link to comment Share on other sites More sharing options...
bansheejoel Posted August 21, 2008 Author Report Share Posted August 21, 2008 yeah im using stock carbs. The first time i was at the dunes my plugs were perfect color, the sceond time my plugs turned gray...i put in a new set and they never turned color (with 2 hours ride time). The engine runs amazing, just lean. I will go put it back together and pull the choke and ride it and let you know what it does..... Quote Link to comment Share on other sites More sharing options...
okbeast Posted August 21, 2008 Report Share Posted August 21, 2008 What makes you think it's lean? What kind of riding is it with stock carbs? Quote Link to comment Share on other sites More sharing options...
bansheejoel Posted August 21, 2008 Author Report Share Posted August 21, 2008 what makes me think its lean is that what ive learned is that you want a light tan/brownish color when you pull your plugs. Mine are pretty white....I do mostly dune riding and once in a great while i take it to my local mx track and rip around there. I just put the pipes back on and took it for a ride...pulled the choke when it was idleing and it shut off....i did it again when i was riding and it ran like shit and smoked alot. Its also dripping gas out of my left carb overflow hose...would that do anything?? Quote Link to comment Share on other sites More sharing options...
Paddleboy Posted August 21, 2008 Report Share Posted August 21, 2008 then that made it too rich. i dont think your lean. just put the old plugs back in and go by the colors of them haha Quote Link to comment Share on other sites More sharing options...

okbeast Posted August 22, 2008 Report Share Posted August 22, 2008 Look at the jetting FAQ, you can't just look at the ceramic to get the color. You could ride the dog out of some plugs and they'll be brown as hell, but that won't really tell you if it's fat/lean. You need to do a proper plug chop.
