That's the second blank with a red X that you've posted tonight.

Sam. 
I never noticed Sam, I guess the images weren't there for a bit?
Oh well, at least they are now.

After I get the 250 Jawa done, I'll still have some bit left over (another frame, a 350 Twin engine minus the cylinders and heads) and, who knows, maybe I'll make an attempt to build a radical (for a Jawa) bike out of that using other parts,
IF I can come up with the needed engine parts first.

Maybe along these lines, but noticeably different. Like I'd probably use a Jawa Frame. Although, I DO have that RZ350 Yamaha
Roller 
and
IF I went through the 350 engine and modified it to the "Factory Performance Specs", might just prove interesting enough.

Now, this doesn't mean that I'm veering away from the Hondas.
