So ive got a 4bt in an 85 prospector with 3,55 swapped gears.I tach at 2000rpm at 70mph.needless to say it hard to keep it from lugging in 4th or 5th when im not quite up to speed.when im cruising below 55mph in 5th theres a rattle through my stick,anyone notice this too?Ive got the nylon pilot busshing fix so i know its not the pilot bearing clearance.

 

mine did that as well. The TOB fork is actually directional which was my problem i believe, although I also did my input bearing at the same time.

 

Throwout will rattle like that

 

through the shaft?It rattles pretty good at certain rpms.I can feel it through the grip.When i squeeze the grip on the stick i can quiet it down which makes me think its a shift fork
