the bowl finally arrived after 6 weeks as it had to be ordered from Japan so i got the carbs, mikuni fuel pump and the primer installed today big plans for the engine this winter ive got a low water pickup coming and i am going to weld an above water exhaust housing on also planning to port my engine and possibly get the crank balanced as ive been told Chris Applebee is taking over the business once again from his son in about 4-5 weeks time ive also got a set of forged pistons on the way as ive heard over 7000 rpm with the stock pistons and it will rip the crowns right off

Loving your work, that's one stumpy tuner! Hopefully you still have some bottom end
