Hello, new guy here. I just bought an 01 400EX and had a couple questions for you guys...
1. The previous owner had the cylinder bored .030 over. I don't know the formula for figuring out displacement so does anyone know what that would make it now? I know, stupid question sorry.
2. I noticed that when I thumb the throttle, a little stream of fuel squirts from a spot where the float bowl bolts to the carb body. I know it's not overflowing like the floats are stuck, it's not coming out of the overflow tube. It's just a little stream shooting from between the two parts. Would that just be a gasket replaced fix or is it something more serious? I think that's what's causing it to bog down when I lay into the throttle too quick, and it idles lower than I think it should. Hopefully I can just change a gasket or something or maybe something got trapped in there when they put it back together because the old owner said he had the carb worked on when he changed the exhaust. Also, given the .030 over bore, would stage 1 hot cam be worth the expense and trouble, or would stage 2? I know there's a lot of knowledgeable folks here so any help would be greatly appreciated.
