Fuel will do it too..just like Mikes bike remember.
Too lean it will pop and sputter,too fat it will pop and sputter also.
Funky intake like Mikes =really screwed up.
Magnets could be broken on flywheel.
Drakart is one of the originals like Short sand car.They are the sh*t.Extremely tough and built very very well.
Any Hayabusa powered car is going to be around 30k
I would definately go with the 2nd engine.The torque is at a lower rpm and I know you arent going to be sitting at the hill all day.
It would be nice to have low end torque for drivability.
These are both Honda engine guys.
The shell Rotella is good but I would use Chevron Delo 400 15w40.Synthetic is only good if you are going to race the truck(extreme conditions) or if you plan on not changing it every 3000 miles which isnt good for a diesel anyways due to all the particulates in diesel fuel and oil.You will find Delo and Rotella at all major diesel repair shops and truck lube places.
The delo is what we have Pete.
