Ok having already covered about 140miles of commuting/necessary travel this week and with petrol well over a quid a litre I read the thread about the diesel bikes and wondered...
Anyone on here got one?
Any ideas for suitable donor engines? (ie more suitable than a rotovator engine that can just about make 40mph!)
Who's ridden the various Enfield conversions, are they really *that* slow?!? Is there a better alternative?
Surely there must be a little car engine somewhere that could be squeezed in... (is there a diesel smart car? ??? )
Over to the spanner wielding masses... ;D
ps. I heard somewhere that BMW were looking into making a diesel bike, anyone know anything about that or is it just rumour? ???
-
...I am listening too...
Funny that, that the Scots are interested in diesel bikes... We're going to get some stick for this, Smudge!! :D
I am thinking about a cement mixer engine in the DR. Obviously will require a pre-unit gearbox, but that shouldn't be a problem?
Although I do have a Norton twin motor (to go with the box). I like the idea of a "British" Supermoto ;D
Which I will entitle the "Super MoFo", to use the street parlance of the day.
I'm off to make pancakes :-*

a friend of mine has a new toyota yaris 1.4 turbo diesel.
64MPG!
he drives normally, but doesn't commute and the MPG is on the rise as the motor 'frees up'.
its a three pot and does have a muted Triumph sound comming from it, so it might be possible to have a derv bike that actually sounds good.
if i could get the same mpg and performace from a bike that this little car gives i'd buy one.
its not slow either, just over 110mph is possible.

Maybe this Kubota tractor unit is more the 'style', or do you think the Yaris has caught up now?

Triumph 'Spitfire' chassis must be getting thin on the ground now.

Hi Smudge, I seem to remember an article in BIKE mag last year on a prototype bike built around a 3 cylinder turbo diesel Volkswagen Polo engine, in line with BMW type gearbox and shaft drive. It may have been Dutch, but I can't remember.
I was down at Stafford a couple of years ago and a bloke had put an air cooled diesel single into an AJS....and it sounded like a dumper truck.
Also the little Froggy cars (Aixam?) are available with a 500cc twin diesel engine and cvt auto trans.

Oh for Mr Creasey and Mr Newall with the Voyager, Phasar layout and the Polo 3cyl layout in place of the Reliant 'Austin 7'! Might be some happy faces about. ;D
Just a thought, little 'pink cloud' moment!
Bring on some Floyd.

A mate of mine briefly owned a part finished project consisting of a Dnepr rolling chassis fitted with a three cylinder Diahatsu diesel (900CC?)running through a Dnepr kickstart gearbox :o I believe he did have it running ( Bas%$*d to start though) but sold it on before it was finished.. I think it ended up in Germany. He later had a dnepr outfit with a Morris minor engine for some time known as Hardly Decent which i think is still around.
-
In fact there is a page full of them here

I've ridden an enfield diesel and it wasn't too bad up to 55mph. But that was all you could get.
I'd love a diesel engined sidecar outfit, but I'm not sure I could cope with the constant hassle every time I tried to fill it up

There is a yahoo group. Lots of talk about ex-stationary engines and Kart type torque convertors. The problem is that diesels small enough are designed to be static. This means they are either on or off, which in turn means 5 gear changes up to 25 mph then just ride the throttle.
There is a company in Germany putting twin static diesels into Ural's. The price was stupid.
I still want one!

Hasn't anyone seen these diesel quad bikes that farmers use? Single cylinder and they fly! Electric start but shaft drive, now that would fit in a trailie nicely.
See you at the Beerfest (Dragon)

NOW you're talking! Got any makes/models? Should be ideal for conversion because they'll already have a useable gear/rev range and be built to more or less fit in a bike layout...
Squeeze one of these into a small traily / roadbike and that could work very well! 8)

er, £6500 for 26bhp!
a 26bhp enfield would give about 75mpg, and would cost a third of that.
or a cg125 with 100mpg.

Exactly the problem unless mainstream manufacturer/s build a sensible diesel bike (Or even a sensible petrol bike who's performance/economy could better a Royal Enfield designed in nineteen fluff ffs ::) )
Was daydreaming the other day and wondering how the Hayes engine from the KLR in an MZ tour rolling chassis would work... bl**dy marvelous I should imagine! If only Kawasaki had the imagination and the bottle to steal a march on the rest of the industry...
Or they would even sell us the engines at a reasonable price and let us make our own! (yeah I know, it'll never happen :( )

lol, I don't need the book to be an anorak Bill, despite my current employ, amongst my further education was an HNC in Automotive Management, another HNC in Auto management with Automotive Engineering and an NC in Auto Engineering... and swmbo is a professional Transport Planner :o
Part of the reason I find the fuel consumption of bikes so offensive is that I understand the reasons and have a decent idea what can and can't be done (and don't start me on the industries "safety improvements" for cars... >:( ;) )
-
Could just buy the Yanmar engine as used in the quads - mind they cost nearly as much as the quad...
LOL

The Chinese make a Yanmar "Clone" that's the basis of most home builds. Drive either a surplus brit/harley/Ural/BMW separate gearbox or a Kart type torque convertor and Roberts your aunts husband. Whole lot off e-bay comes in about £1500 on a good day, then you need to weld up a mounting set.

still dear, but its getting to be a bit more realistic...
This guys had a good bash at it. Looks pretty good...

I have often thought about this subject. The problem is that most single cylinder Diesels don't rev very high and are not very powerful and would shake your teeth out. I keep looking at the vehicles I work on at work like the latest vauxhall combo 1.3 very light 16 valve and go like hell. The block is not much heavier than a good motorcycle and the rest of the engine is mostly alloy. Then only problem comes in sorting out the engine management as all new vehicles these days have very complex ECU and security systems and this would take a lot of sorting out and you need expensive equipment to do this. I think the Kubota small engines are nice and compact but I don't think there would be enough power to make a useful bike engine.

I remember seeing something on one of the Sky channels last year or maybe the year before, where there was a diesel engined bike being made for the US Military. I can not remember the make or anything but it looked like it went pretty well.
-
Yup that's the diesel engined KLR, the Yanks have been using it for iirc about 5 years now, here it's still under testing ::) no doubt because the mod played with the spec/design to save a couple of quid and/or tried to change it to make it all things to all soldiers instead of just paying for a tried tested and effective design...
"smart procurement"... don't get me started >:(

What ho Smudge,
Damned good of you old chap not to be to rough on some of the brass, Whaaaaat?
They'll re-badge it the Euro-Bike or maybe Diesel-TSR2 ::)
Of course we could always purchase the Indian Army Enfield version with some 'lightweight' Lister engine in place!
Off for another gin-sling and the bungalow in the warm foothills of the Hymarliars, Whaaaaat?
Toodle pip, Hinge.

Was typing a long involved answer here but we're getting off topic in a way I don't want to :o
So back to the subject, diesel is unfortunately not a viable option yet, so I am looking at a used CG125, they are a known quantity and I could get a good used one a chunk cheaper than a new copy of unknown provenance.
65 mph (give or take) and an average generally of around 100mpg (although the one I used for a while for despatching was returning an *average* of 120mpg used for town work!) That's not too far away from some diesel conversions but with no insurance issues, spares off the shelf and everything easy...

I ken what you mean! ;)
