have converted a ktm 250 exc to super moto for the mrs, she ran it as 250 last season , have fitted 450 barrel and piston this year to make it 350, but is very restricted by 250 head.
be told 450 head fits witch it does but can't get cam chain to fit, 250 lenght to short, put extra links in and its to long!
have I got wrong head?
or are their half links avalible?
have been told head is 450 but it might be 525, am I right in saying 525 head is taller than 450 by about 2mm?
any help or info will be gratfully recieved.
many thanks
