I may have messed up… the air filter on my XP1K was dirty this weekend and I din’t have a replacement. It seemed like it may have been starving for air so we took the filter off and hose clamped a sock on the intake instead of the filter. It went like crazy for a while but after about 150 miles it wasn’t running quite right. We went home and my neighbor came over and said we probably got dirt in the motor and needed to get it out. He suggested flushing the motor with diesel fuel to get the dirt out. We drained the oil and put diesel in the motor and then went for a ride. It seemed to rip like mad for about 15 mins but then got really hot so we shut it down. We drained the diesel and put oil back in.

Now the only way it will start is when my brother shoots a solid stream of starting fluid in while I crank it over. It starts but smokes a LOT. What should we do now? Maybe it needs another oil change? any help is appreciated
