Hi everyone long time no see.Been very busy lately well here go's,A few weeks ago I picked up a new to me 89 Yamaha banshee I got it for $400 and it ran OK but the guy that owned it before couldn't get it to run right so I got it home tore her down and replaced everything that needed replaced witch was quite a bit,Well come to find out the guy had the carb slides in backwards and the left carb had striped cap threads so I had to pick up a new carb BTW it has tors eliminated as well.I got everything back together and it runs 100% better but I did a plug chop and it was way lean so I ordered 220 jets it had 200's in it well I tried them out still way to lean the only other jets I had on hand was 270 mains so I tried them out and well it ran way to rich as expected lmao so I'm thinking I'll pick up some 240 245 and 250 mains and try those out.Some details about the bike its all stock except for its bored over .20 it has opened air box (no lid) yes its sealed with nuts and bolts through the filter cage and airbox so the filter doesn't pop loose.And I live about 800ft above sea level so my question is this normal for the jetting to be this rich for these little mods and only 800ft? it idles fine and starts with first kick but it does have a little hiccup between 0 to 1/4 throttle but not much.the carb is set at 2 1/2 in on idle screws and the fuel screw is a 1.5 out also the needle is set at 3erd clip.And as always thanks for all the help in advance guy's.
