a bottom end rebuild or a top end rebuild. i've got one of each but i wanna do the easier one 1st so i know i have a running motor when the snow melts. then take my time time doing the harder one and just have it as a spare.

then 1st 1 has 2 bad rod bearings and a good top end

the other has really low compression but has a decent bottom end from what i can tell.

thanks

easiest thing buy new motor!! id guess top end is easier, cause id be scared about spliting the case and then there is tranny gears yikes!! but i have never done either.

Swap the top end

But if you have to ask, its probably not the job for you!




top end job is a good day of work

bottom end you need micrometers, and you need to know what your looking for on the crank and rod bearings that way your not assembling a time bomb

buy another motor, put in bike, good for spring...

take good top end, put on motor with good bottom end, keep as spare...


in the end, you will spend about the same doing this as you would getting parts for the two broken motors and fixing both... and its quicker, and easier...

I have taken top ends apart. its not hard just time consuming...bottom ends on the other hand are alot more involved. if you have to ask then that most likly means youdont have the knowledge and tools to be doing what your talking about doing. honestly for all the time you will put into doing what your talking about it would be ten times easier to do what john said to do

ok, well i dont have the money for a new motor. i dont have the knowledge but i do have the tools (just have to borrow em from our machine shop at work) and shop manual. but from the sounds of it i'm just gonna take the good top end and put it on the good bottom end. hopefully it'll last long enough to do learn/do a full rebuild on the the other one. gotta learn somehow and the 2nd motor was dirt cheap anyways.
