Cause the Pre Unit can haul ass too , ifits setupright . ( They take BIG valves too . frames a bit useless )
theres a few rickmans , & things about too . The late model engines are tougher . plus a few T 90s thatll take the T100 Barrel .
AND the TR5T Adventurer . Twin 30 mm carbs dont hurt . Late barrells aledgedly take .40 over 650 pistons . Whichisonly about 3 mm .
Pends what you use it for , I guess . Theyre light & fast & handle well . the exotics were unknown to the masses once , so were dirt cheap .
Likely youd just put a siamesed exhaust , or whatever , on . Dual high pipes ? . Were a few 74 disc brake 500s too .
really its a ' triBSA ' B50 with T100 engine . dunno if the dual carbs fit ? Bigger F brake for roadracing'd help . 74 B50s used to be giveaways , 20 years back .
