For an '89 blaster does anyone know what the torque spec's are for the cylinder head? Also what size is the stock main jet and pilot jet? Thanks for your help.

18-20 ft pounds on those head bolts. (Shop says 18 and the Clymers says 20) Dont know which is correct or why they are different.

your 89 stock main is a 220 they changed the size in 90 I think it was. If you want to play it safe put in a 230 there was a reason they went up a size. (maybe to lean)?
