Hey all, my father just acquired a trailboss 90-93 year model 6x4 with the dump bed on it . Its in kinda rough shape but does run fairly well considering the looks. I'm not too familiar with these bikes and am looking for a good source for a manual or parts info.. I know it is a 2-stroke but not sure what size. possibly a 400?? or were these only 250's. any help in the right direction appreciated.

 

It might be a Big Boss 4x6. Try this LINK. Its a good place to look up parts.

 

thanks, I think that is what it is.
