Wassup350 Posted December 18, 2003 Report Posted December 18, 2003 I know this isn't Banshee related, but when i ride my sled it cuts out when i floor it. I checked the spark plugs and they are dark brown. Which i think is just about on the money. It's a 1992 Indy 500 with a 1996 xcr 440 exhaust and 34 mm carbs. With 250 main Jets. If any of you can help me that would be great. Quote
Banchetta Posted December 19, 2003 Report Posted December 19, 2003 Sounds like the pilots or needle height....Start there first. Does it start hard or very easy?? W/ choke or w/o... Quote
Wassup350 Posted December 20, 2003 Author Report Posted December 20, 2003 Its not that, it starts in like 2 pulls. The plugs are a lice tan color which looks near perfect. I think it may have something to do with my fuel pump but im not sure its wierd. When i hold it at WOT for around a minute it will ripp very well then start to cut out. Then today i was riding it and it did it so i parked it and it wouldn't start back up and it kept flooding. Quote

Tan is too lean, you want a brown color....you might be running out of fuel if its cutting out after a few seconds of holding it wide open....Its starts in 2 pulls w/ choke or w/o?? If it starts w/o the choke, then you might be too rich on the pilots, try a smaller pilot...what kind of sled are you running??? I know Polaris sleds run a lean needle. I raise the needles one slot and they usually tear better on the low end.... Quote
National Banshee Posted December 24, 2003 Report Posted December 24, 2003 Pull out the inlet needles and check for restriction behind the seats. You will have to unscrew the brass seats from the carb body. It's very common to have dirt or fuzz get trapped behind the seats. This will cause a restriction in fuel flow, and it will run out of gas. If you let it idle, it will take off again for a minute and then do the same thing. In other cases the dirt will hold the needle open causing it to flood just as you described. Quote
