ChippewaTSI94 Posted July 29, 2008 Report Posted July 29, 2008 Exactly what the title says... I pulled apart my top end after having some issues with the right cylinder not firing, and I found my right piston to be completely blown. Top is melted to hell and back, and there was a small hole blasted on the edge and smashing the rings down. Also, the skirt is missing a rather alarmingly large piece. Don't worry, I'll post pics when I get home! In any case, the left piston is damn near spotlessly perfect, not a single mark or scratch on her. I know both sides are running the same main and pilot jets, as well as the same needles (on the same clip). What could have caused such a drastically lean condition on the right side only? Could it be the right side carb was running out of fuel quicker (mismatched floats), or has a bad reed? The bolts on the air intakes were all snug and tight, so I doubt it was an air leak from that location. Anybody have some ideas? Quote
xXBlessedWithDeathXx Posted July 29, 2008 Report Posted July 29, 2008 all i could come up with would be a air leak. if the carb was running out of gas i would think it can cause that. that would be a lean condition. Quote
LS1Inferno Posted July 30, 2008 Report Posted July 30, 2008 yeah the right can run our of fuel faster then the left because the line is longer if its stock. and air leak, detonation, or a single grain of sand, dirt, w/e in the main will do it too, Also the choke tube coming loose would do it too on just the right, my guess is air leak do you have the hell we call a boost bottle?

Check the intake boot for cracks in the rubber. This is common on banshee's. Quote

ChippewaTSI94 Posted July 30, 2008 Author Report Posted July 30, 2008 Nope, no boost bottle on this 'Shee. I will check the intake boots for cracks, though, as I haven't looked at that area. The crossover tube seemed to be on tight with the clamps, however. What should be my next course of action? Clean out the carbs, mains, etc. I assume... but assuming the right carb ran lean how can I prevent this? Modify the fuel line some way, get a dual fuel outlet valve or larger carb bowls? Thanks for the help everyone! Quote
