could any one help i have taken the crank shaft assembly out of my sons txt 200 so i can put new big end bearing in but can't seem to split it so i can get the con rod out ?

Gday, you need a big press and a lathe with a dial gauge at least to align it when going back together. Better still a crank alignment jig. Easiest way is to get your local bike shop (any brand) to do the job for you. Or send it to me in Australia, I do them for free for trials riders.

Cheers,

thanks for the offer but just a bit to far for this pomy to send it to you . thank for the info
