One of my sons just moved to Japan last week for a year with his company. The company shipped his bicycle over for him and indeed it was on the order of $1000 for shipping. So, the prospect of shipping those Suzuki parts to the states puts it outside the range of "reasonable".

Don't work on diesels other than my diesel bike builds.

The first one with a 418cc Yanmar single driving a CVT while the second version is an Aisin supercharged Kubota vertical twin with a belt primary driving a Royal Enfield 5 speed. I lost my shop in town a year ago and only now getting another set up. So, the Kubota's unfinished as you can see below. You'll note in each instance it's a Suzuki GZ250 tank. And then I have a 900cc Kubota triple and another Enfield 5 speed awaiting the next build. Will use either the 300cc Aisin or 500cc Aisin for that build.


Here's the Yanmar during the build.






And here's the unfinished Kubota. Blower is on the opposite side driven off the clutch. I built an on-demand propane fumigation system for this application. But, not sure I'll use it now given the Kubota's an indirect injections lump. And the Savage is on the bench to my back when taking this pic.







And now we're completely off topic for this thread.

Dave will be reading me the riot act here any minute !

As the thread owner, and one of our resident custom builders, I approve of the temporary side track. I agree, impressive fabrication. Would love to swing a leg over the Kubota bike for a few hours.

I am OK with it.  The Tempter thread most likely can't evolve much...until we get a member in Asia that frequently sails his yacht to the US and is wiling to pack a few bikes over for us.

The diesel bikes are cool....I might have a problem owning/riding one for long if the performance is sluggish.  I don't need a superbike - but I don't want a bike that accelerates like a big truck.  Before they started making cars that got decent mileage, I was thinking about using an early Miata and installing a Kubota diesel.
(Really off topic).

Dave , I'm highly disappointed I enjoy it when I'm in trouble or moderated.
But it sounded so interesting I had to ask even at your expense. I saw a diesel bike may be here on SS that was made with a single cylinder diesel with a snowmobile drive unit(one gear automatic) with jackshaft and chain final drive. Did 65 mph and 100 mile per gallon , when I find the right engine I'm gonna build a diesel rat bike just for fun !

Final

I think it might be likely that you could use a stock s-40 piston in an st400 cylinder,and end up with a short throw 450 cc,  redline should be the same as the st400 -7000rpm and give about 30hp .
