running rich

[jmoore]

I just bought a new '04 banshee. It is running like crap. It is butt cold. (10 degrees) Everything is stock w/200 jets. And I am running a 32:1 mix. I think that it is running rich because my plugs are black and constantly getting too wet to run. My exaust is spuing out a heavy wet black gu when I do get it running. It will run for a little while but I think that it floods itself out. Any advice? Please keep in mind that I am new to this machine but am learning quickly about it so throw anything out there. thanks

What elevation are you running at? That doesn't seem to make sense because you are running a leaner oil mixture and your jetting is leaner than or close to stock jetting. Mine came with 230 main jets when it was stock and ran just fine and I'm at about 800-900ft above sea level. Is your air filter clean? Try taking off your airbox lid and see if that helps.

Try a new set of plugs and see if that helps.

Did you just break it in or are you still in the process of breaking it in? You are definitly not running rich with #200 mains and really cold air. They will run like shit untill you can take it out and run the piss out of it WOT, get it good and hot to clean out all the excess fuel and oil out of the case, and cylinders. If you've ran 2 tanks through it, your good to go WOT and run it hard. Plugs will still spark if they are wet, but I'd throw in new ones after the 1rst or second tank of fuel. Plugs are never as good as new after they've been fouled IMO. When the bike is fairly new it will run fairly cold blooded and wont run good untill it has come up to operating temp and ran up through the first couple of gears at WOT. It will get better about this as you get a few hours on the motor. My new stroker motor took at least 2 tanks of gas to come into a stable operating range. Go flog the bitch and shell start to purr for ya. I would change the jetting to as much as 230 mains to run in 10 deg weather after she starts running good.

 

Changing oil ratio will have very little effect on jettng unless you are changing really drastic, like from Yama 2-R @ 24:1 (4% oil 96%fuel) all the way to to say amsol @ 100:1 (1% oil 99% fuel) and it will make it richer (3% total fuel increase = less than one size on the mains). Going from 200 main to 210 main would be 5% increase in fuel and thats not a real big deal.

I am in the process of just breaking this thing in. Literally just going through my first tank. I just got done changing out the jets from 200 to 220. I have not got a chance to run it out though. First jett job. I'm so proud. Does anyone think I should change anything else besides the mains after switching them? thanks again

I'd probably wait untill your through the second tank or more and get it good and cleaned out and running normaly before trying to adust anything else. You won't be able to tell if changes are doing any good because how it runs will change somewhat as the motor comes in anyway. I think it will be fine the way you have it jetted now. If it has any hesitation at 1/2 throttle you may need to raise the needle a clip position but I doubt you will. If it won't idle good after it is warmed up you may need to adjust the air screws in a bit to richen up the idle if it is freezin ass cold out.

I'd say, if your sure it's running rich, pull the air box lid and then run it. See if that helps much. If your running a little rich, that should help it run better.

definitlyneed a new set of plugs to see how it's going to run with your new jets. banshees don't like cleaned plugs only new ones. good luck
