Like CoachGeo said, Johnny, and don't forget it's a mixture of air & fuel. I'd check first for any restriction to air flow as filters certainly do get dirty, clogged, restricted etc. Make it easy on yourself before you make it hard on yourself

Lastly, I know from the personal experience of adding a Cummins 4BT/NV4500 to my 46 year old Dodge Town Wagon: it's far more important to get my drive system, suspension and handling RIGHT and LEARN to DRIVE IT than to try to make the assembled parts do what they were never designed for or capable ...

I dunno XLerate, that combination of transverse 3-4 cyl with a low CG on "extremely challenging narrow mountain roads" could win you the distinction of being the only human known to "lowside" on a diesel flywheel. Be sure to post the video. Well, let's see here: I didn't say how ...

I've got some comments, don't know how useful they'll be. I'm planning to shove a 3-4 cyl diesel transverse into my Kawi, spinning a Harley 6 spd with chain drive to rear wheel, possibly selectable for 2WD in a sidecar build. This for long distance touring but also for local short trips on extemely ...

Thanks for the info, Coach! Yeah these Kubota's are becoming available in Cali thanks to a crackdown on pollution regs. This one's a 4 cylinder, I think about 2.3 L, so it would build a good cruiser bike with maybe a Harley 5 spd? Borderline too big, but with a hack the weight and balance etc. is al...

That's one great machine there! Before I was given my current project bike, a '96 KZ1000P-15 by a recently and sadly departed friend, I was given an '86 Dodge Omni FWD car by another friend. The earliest Dodge Omni's were available with a VW Diesel! My plan had been to fab up a tube chassis, yank th...

My day was absolutely dreamy! Unfortunately it wasn't anything more than that, as usual. All I have right now is the dream, the project bike ['96 KZ1000P-15 Police bike] most of the stuff needed to build a sidecar rig and a plan that includes diesel. I may have located an engine out of a freezer uni...

Congratulations on your clever and successful repair, buddy! Good news, many miles of smiles to you!

Well HAPPY BIRTHDAY, Dave! Congratulations on your find, rare indeed. I remember the little Berkeleys, an exciting little car in the handling department with a very large potential for good clean fun! Really a shame they didn't meet with more success but it seems there were just too many complicated...

Sounds good! As always, hoping the very best for you in this build.

Might look into reversing rotation of the engine? That was commonly done on spark-fired IC engines such as VW for use in experimental aircraft. Should be even easier with a diesel if the injection pump will cooperate.

NOTE: There's another way rather than using a pick or probbe to move innermost reinforcement piece. Drill 1 extra hole a few inches beyond where the inner reinforcement tube will end up. Spot weld a long piece of wire to the inside of reinforcement tube at one end, with wire extending through tube a...

Do not worry, im not offended or annoyed. I would like people to point out when there is something I can do better or especially anything that can affect my safety. I have redone many of the welds, and whilst its the first time using a mig, its not my first time welding. I am also using flux cored ...

You've requested no comments about your welds. My apologies but I must comment and risk offending you. I'd like for you to be around here for a long time, rather than just until your first serious ride. I've been welding since 1965. A motorcycle frame is no place to learn welding. They're more diffi...

Hmmm, not convinced. I think it'd be hard to ever know what you'd actually got / what was going on in there. If the engine over-heated or the oil produced too much vapour could you get a runaway engine also? Particularly when the clutch starts thrashing harder with a hot engine? Why not just instal...

Interesting. Sorry, I don't have an answer to your questions. Do you have more pics and the details of cutting down this CB400 Honda engine into a trans only? Can't see much in the pictures posted and focus doesn't allow any detail when zoomed larger. Some more info on the trans might help with some...

Might be confusing Amps with Watts there? Volts X Amps = Watts, so 12 Volts X 15 Amp alternator = 180 Watt output on alternator.

I'd not heard of an engine manufacturer called Onan. Those with a biblical education might recall Onan as the old-testament character famous for 'spilling his seed on the ground' - thus rendering the term 'Onanist' a slightly pompous synonym for 'w*nker' :mrgreen: FYI aside from Onan's predeliction...

Just adding a jackshaft won't reverse rotation, it stays the same rotation on left and right sides. Hard to explain in text: A sprocket runs in reverse direction according to being driven from inner or outer side of chain between two other sprockets. You can run a chain drive from engine sprocket to...

I was mistaken, CoachGeo, it is not a closed system as I described.

Just an aside comment here: in some cases like the Bosch VE pump if you change the top governed speed by changing the governor spring it can also change the entire fuel curve. That is, while you can sometimes gain top end power along with higher rpm's you can also lose some bottom end fueling and po...

Expansion vessel? Please explain it's purpose in this build? Just guessing but such a thing is normally used in a closed cooling system, where the radiator cap doesn't have the common pressure pop-off lever. Instead as water heats and expands it overflows into expansion tank and remains there until...

Great, hope it works for ya, buddy!

Sorry, I ain't buyin' into it! Don't mean to be insulting because I appreciate you posting it up for us, but... What I see is a 1WD, 2 wheeled motorcycle with a large, inherently inbalanced single cylinder 750cc engine, with a basically inefficient CVT transmission driving through standard chain dri...

After your fuel efficiency mods and upgrades you can focus on setting up the engine's fuel pump timing, injectors, gear ratios to run in the 'sweet spot' for your most frequent driving conditions. I've put a Cummins 4BTA w/ NV4500 5sp, DANA 60HD 4.1 rearend in my big old '67 Dodge truck [7,200 lbs] ...

Sorry for your pain, Alex! Maybe search out some wooden or plastic tools like popsicle stick, tongue depressor, piece of plastic or whatever to manipulate your wires. Skinny vinyl tubing over a piece of coat hanger might do it? Also clear fingernail polish can serve as an insulator wire coating. If ...

Reduce parasytic drag wherever possible: wheel, hub & axle bearings super-lubed with best available synthetic lubricant; highest safe tire pressures; least possible residual pressure in brake lines; least possible drag of brake shoes or drums when not applied. Adjust injection pump injection tim...

I'm impressed! Very nice workmanship and attention to detail, fine looking ride! Rats are cool but I like a class act to cruise around on if at all possible. Just shows more respect for the art of mechanical engineering, beyond the simple nuts & bolts of it! In a way our projects are a testimony...

The total tuned length of the exhaust tract is going to have an effect on how strong it runs too. The engine depends on the proper exhuast length to cause a low pressure reversion wave in pipe to help pull exhaust to exit. Too short a pipe can make the exhaust fight to escape. I've got the correct l...

I suspect I'm techologically bipolar. On the one hand, "If it was good enough 50 years ago then by God it's good enough now!" and just love all that old classic stuff, 'cause I'm an old classic stuff myself. On the other hand I'm just a push-over for high-tech gizmos, flashing lights, digi...
