Kubota Z482 enduro

Postby vwaudiwelder » Sat Oct 31, 2015 9:52 pm

Hello all. I have been a long time reader of this amazing website and have finally built my first (of hopefully many) diesel motorcycles. I still must powdercoat all the fabbed steel parts. I also need to see about getting this bike to somehow reach 70mph. So far I have only achieved 52 mph with the CVT I am using in its highest ratio. I am considering a 5 speed but really want to maximize the use of this first since I have invested all the time and funds in a number of extra belts. If a 5 speed will indeed be that much more efficient in the long run due to less friction/heat loss I really should go in that direction. In the interest of reaching my target top speed if any of you have some ideas on what I can do to the injection pump or governor that would be appreciated. I have already adjusted the fuel screw but that has only created more smoke. I do have on hand a VZ21 turbo but I would like to see what is possible first with just minor NA mods. I have posted a photo diary of my DIESEL (nainenkikan/internal combustion engine in Japanese) on my FB page: Jefferson Bello. I hope you like it. I positively love all your 2 wheeled creations. Thank you all for the inspiration.

Start a thread in the CVT forum about yours. What model Primary and Secondary drive you have, your settings, RPM's etc.

VZ21 is too big for such a small engine. The turbo will be right on the surge line; the turbo will have a very short life and the engine will be very inefficient.
600cc engine size is minimum to turbocharge with VZ21/RHB31, KP31 or GT0632 as smallest turbos currently on the market. Above 4000ft (1200m) 800cc engine is minimum.
