recently blew the main bearing in the bottom en to shreds, it is totally gone theres about a half inch of play up and down......jimvpa
You mean the bearing on the bottom end of the rod at the crank OR the crank (2) bearings in the case that holds the crank? Might (75% must unless money is an issue) want to replace the (2) main crank bearings and seals in the case since the wear from the damage more than likely added too much wear on these parts.
i went to the shop to price parts and there is a full bottom end kit
This include a crank assembly too?? If not, better take stock the crank to a builder to have it spec'd and check for true/damage or you gunna be throwin' your money away on the top-end parts.
or do i have to ensure balancing?
If this kit you are talking about has a crank/rod/reciprocating bearings/and piston together then they are probably balanced to each other. If you are talking just getting assorted parts then balancing is not really a big issue as much as making sure the stock crank, if being reused, is true/not damaged.
