Ok why can't I locate the output shaft and inner gear anywhere bike berry has a shaft but no gear they told me but I'm not sure it's the same shaft I need and I have no clue how the gears attached to the shaft I can buy new gear box but that's too much money I need to be able to replace the shaft beings on how it appears as if that goes bad quite often . Ok what happened to mine is the end that sits in the bearing has worn down and close to breaking off and it makes sense that would happen with the load that they receive i just want to know why this part is so hard to locate again im poor af or id just order a new box im really liking this four stroke but if i cant afford to fix it im going to have to quit whilst im not to far in it , please advise this dummy !
