My banshee is a 4 mil dune port +4 timing fmf pipes cool heads. Its at 155 psi so I run a mix of race and pump gas, 50/50. It was dynoed tuned and started 2nd kick every time.
Wednesday getting ready to go to the dunes, I have to kick and kick to finally get it started. I was guessing that it sat for about a month so, and it just need to get the fuel back in the carbs. Also I noticed a small amount of fuel on the floor when I was starting it.
Friday when I got to the dunes, it was hard starting but once I got her running shee ran great. I went riding for about 30 min and headed back to camp. Got back ate dinner and went out again. I was running up a slight incline and the bike died. I tried starting and no luck. I let it sit for 10 mins or so and then got it to start, drove back to camp pulled plugs and they look oily so I cleaned them up and it fired back up again. So I took off again and just about the same spot the bike die and this time tires stop spinning. I tried kicking it over and it wouldn't even turn over. I let it sit for a few minutes then kicked it over there was no compressions. Bike kicked over supper easy, way to easy. Got towed back to camp, bike is toast. I noticed the exhaust pipes look light gray with no oily residue. I guessing bike got lean some how?
I can put in a new top end but I'm wanting to know the cause so I don't keep going threw top ends. The bike had about 12-15 gallons of gas ran threw it on a total rebuild. Any thought on where to start?
