The 1970's are back again! It reminds me somehow of 1970's concept bikes. Maybe the bike designers have been going through back catalogues of old bike magazines for design inspiration? :wink: At least it's a bit of a break from basically producing Honda "knock off" clones! :P The performan...

As gilburton stated, it should either have a fuel shut off solenoid, or be shut off mechanically by moving the normally spring loaded engine governor link arm beyond it's normal at rest position. Move the arm one way to increase the engine speed (throttle action) to max. Moving it the other way to m...

Yes, gently run a new diesel engine in for at least the first 300 to 500 miles when installed on the bike is always a good idea, as well as frequent oil changes initially, again around every 500 miles.
Then it should run and idle smoothly (for a diesel!) and be reliable hopefully

The project is looking good Bj-torb! Hope the cvt runs well when it's finished.
Keep us posted how it all goes for you.

That's quite right gilburton, deliberately used for chain inspection purposes! I found out that Enfields incorporated this chain inspection method in their fully enclosed chain cases, several years before Honda incorporated it in their designs! This is used on a Royal Enfield from the mid 1950's. En...

Rotek of Austria are still around, and produce Yanmar clones. They do an 870cc V twin 19hp version at this link : http://www.ebay.at/itm/Dieselmotor-19PS-2-Zylinder-14kW-Kleindiesel-Rasen-Maher-Rasenmahermotor-/111152797386?pt=Ersatzteile_Zubehör_Landtechnik&hash=item19e13916ca and still have th...

One other modification I came up with last Autumn, which might interest some other Diesel Royal Enfield owners, who have the electric solenoid fuel shut off fitted. Mine was a standard fit, fitted by Henry Price. I found that the fundamental flaw was that if the battery went flat, or there was an el...

Some internal rubber anti- rubbing strips were added, where the chain case sits against the swinging arm and the rear drum assembly. Then a final bit of adjustment of the plastic fill in panels could be done, using my hot air gun and with care with my fingers!! slowly moulding the plastic edges arou...

Since there are quite a few diesel Bullets around, I decided that this mod info would be quite useful. As I had the opportunity and access, whilst changing my rear wheel bearings, I decided to get on and finish my fully enclosed chain case project. I was getting a bit fed up with the lack of protect...

Last weekend was changing the rear wheel bearings on old 'Clunkie', due to a wobbly back end, starting to be noticeable at certain speeds. Found a good on-line bearing factors that supplied good quality replacement bearings at a very competitive price. Fitted a better spec. equivalent metal shielded...

What if anything has sidetracked you from diesel bikes recently?! I've been away from here for a while, being sidetracked for the last five months by my Mobylette project. I picked it up as a non runner, and a bit of a 'rolling wreck' for £150, from a damp back garden in Eastbourne. The poor thing l...

That's really great news alexanderfoti, I'm sure that you'll sort out the 'advisories'!!
The bike must have made the MOT tester scratch his head a bit, unless he's come across diesel bikes before!

That's great alexanderfoti getting the bike on the road, after all your hard work - even though the first ride wasn't exactly legal!!
Good luck with sorting out the remaining minor niggles, and keep us posted with your news.

Great Job Erik! The bike looks and sounds good.

How are the vibration levels with your Ruggerini engine at low and high speeds?

Let us know how you are getting on, when the engine is fully run in.

Thanks alexanderfoti - there's always hope for these Yanclone engines! Another excuse why I've been away from here for some time, is that I've also been very busy since the start of this year on another project, a 1970 Mobylette which I picked up cheap at the end of last year. Hopefully it should be...

Just an update on the engine repair/running so far. The engine has run really well last year, though I didn't use the bike as much as I would have liked, due to the lousy weather! The bike got through the annual MOT test in December with no problems at all, and the engine doesn't smoke much at all. ...

Good luck with the welding and the alignment! Especially in this cold weather!

Thanks sbrumby for sharing your 'noisy' experiences with everyone! I'm sure that someone will find your tip useful.

Bloomin' cold! At least 'Clunkie' started first time in the cold, on the electric start. Roll on the warmer weather, or even Spring? eventually......

Noticed over the weekend on 'fleaBay' this Royal Enfield for sale. 1983 diesel bullet.JPG It's a Henry Price ex. demo bike, so should be ok for someone new wanting to get into diesel biking. Here's the info: 1983 Royal Enfield Bullet diesel 456cc 13hp . A recent conversion by ourselves and was fully...

As I shaved my beard off in the past.... Does that make me a biking novice again?!!!!

The old "rule of thumb" is that if the part attached to the bike looks tatty, it usually is, and will fail when least expected and most inconvenient!!
So if the bits attached to the motorbike overall look good, they generally will be, and will be reliable - we hope!

If you successfully fix all the problems, the motorbike will eventually be reliable to commute on. After I sorted out the engine on mine, with better quality bits, it starts and runs first time and is reliable. I regularly use the motorbike, and will be using it to December. Then it's winter break t...

I wonder how may EU bureaucrats involved in this nonsense have ever ridden a motorbike, or even swung a leg over a bike? I think virtually none! They give the impression of being as 'brain dead' as a biker coming off his motorbike in an accident, without wearing a helmet!! Also wonder if they take a...

No it's not mine!..... Honest! My Oilfield/Enfield was 'lurking' around Twickenham Tesco! Don't worry about hanging around and photographing diesel bikes, even with 'dodgy' camera phones - most diesel bike owners very are used to it. I've had mine photographed twice at Tesco, and at least once outsi...

Welcome to the DieselBike forum - as for engine choice, it depends on how much you've got to spend, and how heavy you want the bike to end up! I've got no personal experience with the Ruggerini md191/151 engine, but there may be someone around that can assist. You have to watch out that the engine i...

Unfortunately life is never simple or straightforward, especially when it comes to burning fossil fuels in an internal combustion engine! despite what the authorities 'fret' about, the main damaging pollutant is carbon dioxide which is gradually changing the make up of the atmosphere, which the resu...

Thanks for the useful information Erik, a good alternative to the original Enfield fit.

Thanks for your latest project info Mouse, pity that the pics have suddenly disappeared! Keep us updated with the latest developments!
