That kart is the twin to mine.
same everything.
i've i.d'd it as an early gk400 but may have to reconsider.
never heard the honest charlie story but i don't disbelieve it.
if it turns out they are rebranded gk400's it would make zero difference to me.
rebranding doesn't usually involve changing anything .
they just call it something else and sell off the obsolete stock that way.
one of my gilsons was factory modified to ride about three inches higher and probably came with a 4 stroke.
zero difference between it and the race version except for the flipped front axle and lower location rear bearing area.
i have a later gk400 with aluminum steering wheel.
the rear sprocket is bigger and the brake system still drum is different too.
we need more info!!
