Port designs? chamber specs ? gearing ? wear on bore? weight of complete unit? etc Gees Shelpi you have posed a tricky one. Best find a carb, then the old hard work plug chop stuff.
yer Tim ya right, why I said 34mm is I got one and the spigot is the right size for the 1974 MX250/360 inlet manifold come reed block, So want some specs to start me off in the right direction, am getting a pipe to lend from freaky see how it goes and then make one to suit, running DT400B cdi, gearing will use what we got then will change to suit, motor apparently new (rebuilt) only raced on sunday twice, looks good when ya perv up the exhaust port, will try to get it as light as possible.
This is a curry in a hurry build from scratch for Pt Augusta, so any input will be greatly appreciated
