1980 Dodge d-50

Here is a new to me Bike. Asked Business owner to install slow throttle. glad he did !  The white truck - It has a header & a blown out muffler, Weber 2 barrel carb..  The Scorpa has a new spark arrestor fresh muffler packing.  I like my truck.gets approx 45 mpg.  Gasoline here in washington, non ethanol is nearly $4.50 per gallon.

What are your tricks for getting that kind of mileage from your D-50?

Thanks

There were quite a few versions of this 2 liter engine. most had timing belts-   the engine in my truck is- G52B. japan industrial engine. counter balanced with timing chain. used in many fork lifts in japan years ago. America emissions required this to be a jet valve motor..  This mickey mouse idea was removed out of the head, replaced with bolts. 4 of them. - Got rid of the mikuni carb- put a weber 2 barrel on.- gas has been spendy forever in europe, weber knows how to build a carb correctly. --  it runs on 1 barrel 99% of the time, the secondary barrel used a counter weight to open it-- it stays closed unless the motor is really wound up. The carb has no power valve enrichment  like nearly all usa carbs have-- holley - barry grant-- ect ect.  I take off slowly-- do not lug or rev  it--  sorta  short shift it.  on long up hills go into the truckers lane- go to 3 rd gear.  There is one like mine down the street, old man has it-- told him, you ever sell it-- i am right down the street if it runs decently-- clear title- i have cash dollars.   what happened to the good ol rigs-- several years ago- price of metal skyrocketed-- everything got crushed- sent over seas.darned shame. Oh, i only run non ethanol gas in everything i have-   this is a big help for milage.

Oregon? what part ?   2nd house i flipped was south of Pendleton.  Pilot Rock, Or. totally safe there. Never took the keys out of the cars-trucks- never locked the house-basement- gone for days dirt biking- kayaking, Told the neibors, you guys are welcome to the tool boxes in basement- but clean the wrenches up before you put them back in the roll aways, and-  The 1/2 inch torque werench is NOT a breaker bar !!  leave in the box. !!  Pilot Rock is a sawmill town--  good jobs there too-   but i moved to central wa.  Ephrata, wa.   big house- 5 br, jacuzzi, showers soaking tubs--- bout 3 k sq ft--  life is good-- lol.   kinda miss oregon though-- dave.

Hi Dave, 

South of Portland, rural. Been here since 1962. Secure here too, but not liking the population growth so much....traffic. My Dad used to say "where are all these people going"! A certain % of the population is always going somewhere. It is just that population base is growing faster all the time. I'm thinking of moving farther out, now that I'm retired. 

I've got a 1987 D-50, but with the auto trans. Was one of those Air Force D-50's. Has all of the junk you removed. Mileage doesn't come close to yours. Never will with the auto either.

It still recall the comment of an SU engineer many years ago, when I was waxing lyrical about twin Webers. "Anyone can design an hole."

I think gasoline has been spendy in europe for long time. Its become spendy in usa this year. All carbys - aftermarket - holly-barry grant- ect-  have a fuel enrichment divice. its called a power valve. its located between the main jets. At light throttle settings, engines have high vacume.-- as the load on an engine increases, it loses vacume.example- a 6.5 hg power valve- when engine vacume drops below 6.5 hg, the valve opens. A standard flow power valve is main jets X 8. this quenches -cools combustion chamber temp -slows down spark knock and adds engine horse power and  drains the gas tank & money quickly.  The Weber on my little truck does not have a power valve. This helps to go long time between gas fill ups.  There are carbs for motorcycles that do not have pilot & main jets. The fuel is metered tru the needle valve. Its called a Lectron carb. A advanced version of a lectron is called a Smart carb.--  VERY spendy. I put a standard 38 mm Lectron on a rm 144 suzuki. - It would run like a scalded dog on top end, but it had a rich hitch off idle i could never stop. several types of needle valves slides later i put it back in its proper place- the cardboard box it came in. Bought a Kehin 36mm pwk air striker short body carb with jd jetting kit- Thunder products quad flow torque wing.  --  runs really good.  Thunder products torque wings only go down to fit 36 mm carbs.  I would like to have one of these for 28mm Kehin pwk series carbs. Put one on my Scorpa 300 !!     They make a HUGE increase in power right off idle  -- with proper re tuning-- torque wings cause a engine to become richer off idle - into lower midrange.  As usual. paedon my spelling mistakes-- I have a decent command of english--- but my spelling----- lol.

There are some things you shouldn't joke about, you've crossed a line there!

(I had a '63 Triumph 2000 once upon a time, loved it to bits but it never returned my feelings)
