I did speak to lane and my current jetting is really close to what he recommended. I was just looking for guys running similar setups. I’m a little richer than what lane recommended so I will stick where I’m at for breakin

I’m currently building a 421 driveline low port setup and I’m looking for a conservatively rich starting point for jetting. I will be running the cylinders as cast on pump gas, keihin pj 34mm, k and n 6” pods, slip pipes. What would you guys recommend for a starting point?

That’s a real good question for whoever built this thing. There’s orange rtv all over the damn thing. Sent from my iPhone using Tapatalk

That’s the plan over the next few weeks. The bike overall is in pretty rough shape so I plan on taking this winter to get it cleaned up and everything rebuilt. Would you guys agree this failure could be head gasket related? There was some damage to the other cylinder too, just nowhere near as bad. This morning before it let go it had 115 psi of compression on both sides. I thought this was pretty low with 21cc domes. Sent from my iPhone using Tapatalk

Just bought a new to me banshee and within thirty mins of run time I lost a cylinder. The previous owner bought the motor as is so he doesn’t have any idea how it’s built. Could you guys help me out identifying this cylinder? The crankcase was also half full of coolant on the side that I lost so I believe that is what caused all of this.

I just bought a new to me banshee and I’m looking for a little advice. All the info I have on the motor is that it’s a 421 cub. CPI in frames v force reeds keihin pj 34 carbs with k and n pods. The bike is very boggy off idle and all the way through the mid range. I’m wondering if you guys could help me with a starting point as far as jetting goes. This is my first banshee but not my first two stroke so I feel like I have an uphill battle of trying to tune this thing.
