I am seeking advice to help build a wood gasifier around a motorcycle. That’s right a big-ass wood gasifier around a motorcycle, not in a trailer or side car. I DO NOT want to build a charcoal gasifier, I want to take on this challenge. I know it might be heavy and awkward looking but I intend to balance it as best as possible. I have built a wood gasifier before and have a series on youtube called “Wood Gasifier Build For Dummies” my channel name is TontoBob. I will document this whole build as well for public knowledge if I find that it is do-able.
I have been searching craigslist for the right motorcycle, I want it cheap enough to weld brackets on the frame and not care($1000-$2000), powerful enough to hold me (170 lbs) plus a wood gasifier with full hopper and all (200-400??? Lbs??), fairly fuel efficient for less wood consumption, lower RPM than 8000???, and if possible go 100mph on gas so I can hopefully get good mph on wood, not necessary though. So far I have found many 1980’s Honda Rebels, Honda Shadows, Suzuki GS bikes and things like that. I have not decided yet but here are the specs for a 1988 Honda Shadow VT800:
Engine Type: 798 cc, 4 Stroke - Liquid Cooled - V Twin
Engine Bore and Stroke: 79.5 mm x 80.6 mm
Valves 3 valves/cylinder
Claimed Horsepower: 74 hp (55.2 kW) @ 7500 rpm
Transmission type: 4 speed
Final Drive: Shaft
Tire - Front: 100/90-19
Tire - Rear: 140/90-15
Brakes - Front: single disc
Fuel Capacity: 12.5l
Dry Weight (without fluids): 225 kg (496 pounds)
I think this is a likely bike for me to choose or one similar in CC’s or HP and engine type.
So with that all said, can I ask for some advice on possible dimensions for hearth zone, reduction zone, air nozzles, biochar zone, and anything else that might help? I am planning on mounting the gasifier on the back of the motorcycle, 3 conical cyclones on the right side, an aluminum radiator on the front, 2 fire extinguisher filters and a final cyclone on the left side before snakeing pipe to a homemade carb into the engine.
I am open to ALL suggestions even if its telling me this will never work, but I want an explanation in that case to. The thing that trips me up on this is the high horsepower, high RPMS, and odd engine dimensions compared to a truck or small engine that gasifiers usually are built to run. Thanks!!
