Are these 165’s DI or IDI?

My Listeroid is a DI engine and it runs well on both BioD and WVO.
BioD - No mods needed. (Except for changing the crappy Indian rubber fuel line from the tank to the fuel filter. It will disintegrate.
Modern fuel injector hose has a liner which is compatible with biodiesel.
WVO - I heat the WVO on the way to the injector using a Ni-chrome wire heater wrapped around the steel injector line.
The other option is a coolant heat exchanger which passes coolant heat to the wvo on the way to the injector pump.
Blend - No mods needed (If you choose to run a blend, then no fuel heating should be necessary as the viscosity is already adequate.)
By the way.... for a lister(oid) you don't have to go to the trouble of making biodiesel.
They run very well on cleaned/filtered waste vegetable oil.
Also consider a blend. 80% veg oil and 20% unleaded gasoline.
Just keep the temperatures high enough for clean combustion (coolant thermostat).
Start on diesel for warm up, then switch over to WVO. Afterwards, switch back to diesel for 3 minutes or so before shutdown.
Where I live methanol can be purchased in any quantity you like (up to 44 gal drum size) from industrial suppliers. However for some reason it requires police clearance.
If you know anyone running a moonshine still they may be happy to give you their foreshots and heads which could be redistilled/compressed into something fairly effective.
Bulk Sodium Hydroxide available at farm supply stores. Potassium hydroxide available from soap-making suppliers.
Don't know if there is a proper way, but i would look at someone's Harley and copy that, I'm sure those guys have got exhausts waxed. I don't think you need a 4" pipe either. My SR2 has a factory 2 into 1 manifold with a 2" pipe off that and through the wall
