need some help

See if your local dealer can bore it for you. I have my local Yamaha dealer and an Auto parts store that can bore my stuff. That will save you on shipping costs too.

on ebay, ther a place you can send in your jug, theyll bre, shotpeen , beed blast and send a top end rebuild kit for like 170.00. i think its gnr atv warehouse. anyway, itll show up in "blaster motor engine" on ebay stores, it saves the trouble of finding a machine shop and youll get everything you need right away. the store has like 2000 positive feedback so i think they must be reliable. i havent gotten one done there but its an option...
