Actually, the target was to atkinson time a GPZ 500 but the carbs are a big issue.
So either I found an injected bike to mess with or I buy a GPZ and then an injection kit for a GPZ.
Not likely to happen for quite some time.
Also, I am worried about the antagonism between short stroke(high revving) and atkinsonned engine.
So my reference plan is to get an EL 250 (a kind of cruiser) and a GPZ or the like engine to build a squarer if not long stroke engine and then atkinson it.
Again, not likely to happen for a while since EL 250 at the right price are not very common around.
