Looks like a great build. Wheels & truss fork look like they will hold up well. I'll be watching your progress, keep up the good work. What are you thinking of using fo your engine?

Wow! Build your own engine, that's a task that most of us only dream of doing! If you do decide to go that way, please do a seprate thread on it as I am sure many would like to follow that build.

I was glad to get a closer look at your truss fork in the back ground of your third photo, looks solid.

The price of an engine across Europe need not be too expensive. What size do you want it to be?

thank you all for the interest Ludwig it isn't a problem sourcing an engine is the fact that I have fell in love with these simple hoglet engines so I wanted to built my own as for the capacity here in Greece we have a lot of Honda c50 bikes so I will use plenty of Honda parts such as crankshaft and rocker arms so I guess it will be 50cc or 100cc if I make it v twin my concern about the v twin is that the cylinders wont be allined because the connecting rods will be side by side

Do you actually need the cylinders directly in line? If you do, you are consigned to the self build path.

If you merely need a small V twin, then people on here have successfully used 125 Honda and Yamaha chain drivers.

The choice, direction, methods are yours. Ask every time you come to a decision point though, there is a large amount of information on this forum for you, which will hopefully save you time and expense.

ludwig so true I should ask first in any case some damage has already happened but I cant go back so I have to evolve existing parts. as for the engine the idel would be the cylinders were alined but I have already laser cut connecting rods so if it will end upv twin the rods will be side by side like the ducati l-twin which brings one cylinder centered and the other one aside like in this foto

Does the cam have a single lobe, like the old Ariels and the more recent Honda CG engines? Also, is there any advantage to having the follower arms set so low?

While U think, do you know about the Buddfab "1905-ish motorcycle"?
