cobblers, my 1400 did 90000miles then got sold to a bloke to put into an astramax...Originally Posted by jimbob-mcgrew
the 1200 & 1300 setups are interchangeable and pretty much identicalOriginally Posted by jimbob-mcgrew
unless you do some serious head work or the 1300 cam is replaced by a hi lift sport type cam then you will get about 75hpOriginally Posted by jimbob-mcgrew
the 1400 will give about 85-90 on a std 1200 cam & carb and will be reliable
as for the gearbox idea, fine for forest rallying but an absolute pain for any form of road use. you would have to change gear 3 times before 60mph, which is just annoying. the 1400 will pull from 15-115mph in top, I did it.
