Hi Steven - nice to see another diesel bike nutter! Where abouts are you in the land of the long white cloud? I am in Matamata, there is another builder in Cambridge. I for one would be happy to share my experiences and observations on the gentle art of diesel motorcycle building and riding. I recen...

Check out 'Diesel Air Ltd' a UK company - 92kg engine producing 100hp @ 2500 rpm! Torque would be unreal! So would the price. My apologies for not putting a link thingy in this note, I'm a bit illiterate with computers. Cheers, Brian H. PS, google dair aero engine

Hi there Kapis - as far as I know, I'm the only New Zealander (Kiwi) taking an interest in this forum. Diesel bikes are not a big thing in NZ yet, I have seen a couple of Enfield diesels (at a Cold Kiwi rally some years ago) and I have seen a home built diesel at the annual Classic Festival at Pukek...

Hi Stormcoat - I see you are using a starter from a Ford Grenada. Do you have an idea as to the diameter of the ring gear on the Ford engine? It occurred to me that if the ring gear on the Petter is larger in diameter then it will turn slower than the Ford engine. A possible cure would be to fit a l...

Hi Rafael Paul Carter wrote a book about his trip around Oz, the title is "Is That Thing Diesel?" I read it sometime last year, from memory it was the bike you asked about. If I remember rightly they had a few problems with burning out CVT belts and an engine failure. Reading between the l...

Hi Sean I have been having a bit of a look at the posts for some years now, particularly in regard to Punsuns, thats why I wanted to know when the crank problems were overcome. I have a suspicion my 2007 build motor may be suspect. The general idea is not to exceed 3600 rpm, and to be able to mainta...

Yes, it is the 22 hp. V twin engine. Have you had any experience with this engine?
Cheers, Brian

As I noted in my introduction,I am the proud owner of a 2007 year Punsun which I acquired last year. (Brand new). Can anyone tell me if the starter motor is suspect on this year/model or should it be OK? (This engine hasn't been started yet). I spent some time looking into arranging the engine Guzzi...

Further to this issue with the governor, I have done some research on 'electro-mechanical' control of the fuel system. The plan is to use a stepper motor to control the pump fuel rack, this in turn is controlled by a micro processor which has 2 inputs, throttle position via a variable resistor and e...

Hi Sibbo - if modifying a frame is a hassle in NSW, how about building a frame from scratch? It would be a new frame, not a modified frame. Just a thought, cheers, Brian

Hi Raf - indeed I am responsible for that bike! (Which first appeared on the internet on your site 'dieselkrad' more than a few years ago. To this day I have no idea who sent the photo (from a local newspaper), how I found out that it was on the website was through the Kubota Lawn Tractor Owners Clu...

Last year I found some metal chips in the oil when I changed it. An engine strip revealed what I expected - the contact points on the arms of the governor weights had worn, a result of fitting a heavier spring to work against the governor to increase the engine rpm. ( Maximum rpm went from standard ...

Hello from New Zealand, the land of very few diesel bikes. My name is Brian, I ride a Kubota powered bike of my own design which I put on the road in 1994, you will find an article on this bike under the 'Private Production' section of the Diesel Bike website. I acquired a new 2007 Punsun 22HP engin...
